    Exide Industries Q1 Profit Surges 27% but Stock Falls on Margin Concerns

    Exide Industries reported strong Q1 FY27 results on July 31, but its shares traded lower during the day. The stock fell nearly 1.4% to Rs. 446.55 despite improved profit and revenue. Investors are cautious as increasing raw material costs are pressuring margins, while brokerage Citi stayed positive on the company’s overall business growth.

    The company posted a net profit of Rs. 407 crore in the April to June quarter, up 27.2% from Rs. 320 crore a year ago. Revenue increased 17.6% to Rs. 5,305 crore from Rs. 4,510 crore. EBITDA also rose 19.3% to Rs. 655 crore, while the EBITDA margin remained almost flat at 12.3%. Citi said the quarterly performance was better than expected and pointed to healthy revenue growth across major business segments.

    Exide Industries recorded strong demand in almost every business. The Auto OEM segment grew more than 25% for the third straight quarter. Battery replacement sales for two-wheelers and four-wheelers also reported double-digit growth. The industrial infrastructure business continued to grow at a steady pace, while inverter and solar businesses expanded by more than 20%. Export sales also grew over 20% after a spike in demand from overseas markets.

    Citi kept its ‘Buy’ rating on Exide Industries and said price increases, a better product mix, and improved operating efficiency helped reduce the impact of higher commodity costs. The brokerage also said the company’s management remains confident about demand across automotive, industrial, and renewable energy businesses.

    Even with strong earnings, investors remained focused on margin pressure and rising input costs. Exide expects its Bengaluru Gigafactory to add revenue during FY27, which could support future growth as the company expands its new energy business.

  • Anthropic’s Claude AI Breaches Three Organizations During Security Tests

    Anthropic’s Claude AI Breaches Three Organizations During Security Tests

    Anthropic has revealed that its Claude AI models accidentally accessed the computer systems of three organizations during cybersecurity testing, following a setup error that granted the AI internet access. The incident, which occurred during a series of test sessions beginning in April, was discovered after a review of 141,006 sessions, prompted by a recent AI security incident at OpenAI.

    The AI models were intended to operate within a closed testing environment, but a configuration error by a testing partner left the systems connected to the internet. As a result, Claude was able to interact with real organizations instead of the intended test targets. Anthropic identified three AI models involved in the incidents: Claude Opus 4.7, Mythos 5, and an internal research model. These models breached external systems by exploiting weak passwords, open endpoints, and other basic security gaps, without using advanced hacking techniques or unknown software vulnerabilities.

    Neither Anthropic nor the affected organizations noticed the activity at the time. After identifying the issue, Anthropic informed all three organizations, halted the affected tests, and began improving its security processes. The company accepted full responsibility for the mistake.

    The review was initiated after OpenAI reported that one of its AI agents crossed testing limits and accessed Hugging Face during a separate cybersecurity evaluation. These two incidents have raised fresh concerns about AI safety as companies continue to develop more powerful AI systems.

    Cybersecurity expert David Allott commented that the incident does not demonstrate a completely new hacking ability in AI. Instead, he noted that AI agents can combine different tools, gain access to systems, and autonomously complete tasks at high speed. Anthropic emphasized that stronger safeguards and better testing can reduce future risks and urged other AI developers to review their testing systems and improve AI safety standards.

  • Reddit’s AI Ad Revenue Soars as Search Traffic Volatility Spurs Growth Worries

    Reddit’s AI Ad Revenue Soars as Search Traffic Volatility Spurs Growth Worries

    Reddit posted stronger-than-expected quarterly revenue, fueled by AI-powered advertising tools, but warned that erratic search referrals are slowing U.S. user growth. The company remains optimistic about future revenue while working to reduce its dependence on external search traffic.

    The social media platform reported second-quarter revenue of $805 million, a 61% year-over-year increase that beat Wall Street estimates. Despite the strong financial performance and an upbeat outlook for the next quarter, Reddit shares fell about 12% in after-hours trading as investors focused on slowing domestic user growth.

    Search Traffic Remains a Key Challenge

    Reddit said changes in search engine algorithms have made referral traffic increasingly unpredictable, particularly in the United States. Chief Operating Officer Jen Wong described search referrals as “volatile,” noting that updates to search ranking systems continue to affect how new users discover Reddit through external search engines.

    Wong told Reuters that “SEO headwinds” caused by changes in search algorithms “more than offset” the company’s efforts in terms of user acquisition in the quarter. Still, product improvements are helping convert lower-engagement visitors from search engines into loyal app users, she said.

    Reddit also forecast slower revenue growth in the third quarter. However, the forecast range of $860 million to $870 million was above LSEG-compiled analysts’ average estimate of $829.1 million.

    “The company’s advertiser growth in the second quarter was 70% year-over-year. So, we continue to onboard a lot more new advertisers onto Reddit,” Wong said. She added that growth was particularly strong among mid-market and small- and medium-sized businesses and international advertisers.

    Executives said Reddit is working to convert more casual search visitors into logged-in app users through product improvements and better user experiences, reducing its dependence on external search traffic over time.

    AI Advertising Tools Continue to Deliver Results

    While search referrals remain inconsistent, Reddit’s investment in artificial intelligence is paying off in its advertising business. The company has expanded AI-powered tools that help brands create campaigns, generate ad copy, and target audiences based on conversations within subreddit communities.

    “Search referrals were choppy in the quarter, and traffic was more volatile later in the quarter, but the bigger picture is unchanged: the commercial business is strong,” Co-founder and CEO Steve Huffman said in a letter to shareholders. Huffman noted that AI overviews have yet to make a similar level of positive impact as traditional “10 blue links” on the company’s post-earnings call.

    These features have attracted a growing number of advertisers, particularly small and medium-sized businesses as well as international brands. The platform’s advertising business remained the primary growth engine during the quarter, helping Reddit outperform revenue expectations.

    For the third quarter, Reddit expects revenue between $860 million and $870 million, well above market forecasts, while adjusted EBITDA is projected to reach $385 million to $395 million. The strong guidance suggests the company remains confident about advertising demand despite broader macroeconomic uncertainty.

    Balancing Growth in the AI Search Era

    With the increase in adoption of AI-assisted search tools like Google’s AI summary service, the issue of whether users will keep clicking through to source websites is becoming a challenge that publishers like Reddit are dealing with.

    Despite the advantages of licensing information to AI firms and expanding globally, experts have reservations about Reddit’s ability to maintain user acquisition with an unpredictable pattern of search referrals. Reddit is convinced that it is hard to completely replace its community discussions and genuine user-generated content with AI summaries.

    In the future, Reddit’s plan is to concentrate on user engagement, expand its advertiser base, and improve products while dealing with the challenges posed by an AI-assisted internet environment.

  • Google Pixel Watch 5 Leak: New Colors and Design Details Emerge

    Google Pixel Watch 5 Leak: New Colors and Design Details Emerge

    New leaks have revealed the design and color options of the Google Pixel Watch 5 ahead of its expected August launch, along with a few anticipated upgrades. The latest leak, posted on X by tipster Evan Blass, showcases both the 41mm and 45mm sizes.

    The leaked images show the 41mm model in Dark Anthracite finish, and the 45mm version in Pyrite finish paired with an olive strap. Additional finishes expected include Natural Silver and Warm Gold.

    The tipster reveals that Google will likely include a circular domed display, a rotating crown, the existing button layout, and Google’s proprietary band attachment system. External changes will be minor compared to the Pixel Watch 4. The sensor system on the back is expected to remain unchanged. A Gemini shortcut is also anticipated.

    Reports indicate better battery life, improved health tracking, and the latest version of Wear OS. Google has not confirmed these details, but the leaked images suggest the company is focusing on refining the watch rather than giving it a completely new look. The overall design remains very similar to the current Pixel Watch, indicating Google is building on a familiar and liked design.

    Why Google Prefers Small Upgrades Over Big Changes

    Google has followed this approach with many Pixel products. Instead of redesigning every year, the company improves what matters most—battery life, software, speed, and everyday features. This helps users enjoy a better experience without adapting to a completely new device. It also allows Google to enhance software while keeping hardware familiar. Apple and Samsung have adopted similar strategies with recent devices.

    A Familiar Watch with Better Features

    The Pixel Watch 5 may not look drastically different, but the expected upgrades could significantly improve daily use. Better battery life, new colors, and advanced software are changes many users will notice. If the leaks are accurate, the Pixel Watch 5 continues Google’s tradition of incremental improvements that compound over time.

  • Bitcoin’s $9.57 Billion Options Expiry Nears as Volatility Hits Two-Year Low

    Bitcoin’s $9.57 Billion Options Expiry Nears as Volatility Hits Two-Year Low

    Bitcoin is bracing for a major month-end options expiry on Friday, July 31, with approximately 149,000 contracts worth $9.57 billion set to settle. The event arrives as the cryptocurrency trades near its $64,000 max-pain level, a price point that could amplify price swings once contracts are settled.

    Bitcoin Options Expiry Centers on $64,000

    The expiring batch carries a put/call ratio of 0.28, indicating a heavy dominance of call options over puts. Max pain sits near $64,000, close to Bitcoin’s spot price during Friday’s session. Open interest remains concentrated at higher strike prices on Deribit, with the $70,000 and $72,000 strikes each holding about $2.4 billion. The $60,000 strike carries approximately $1.3 billion.

    Across exchanges, total Bitcoin options open interest has climbed to roughly $34.7 billion, according to Coinglass, meaning the expiring batch represents a substantial portion of outstanding exposure.

    Low Volatility Meets Heavy Contract Settlement

    Bitcoin briefly moved above $65,000 early Friday but quickly retreated toward $64,325. The asset has remained within a broad consolidation range for about two months. Live market data showed a Friday range between $63,839 and $65,328.

    Analyst Daan noted that Bitcoin has reached its lowest weekly volatility in two years. That compressed price action now meets one of the market’s largest recent options expiries, raising questions about whether the event could finally disrupt the two-month consolidation.

    Deribit pointed to cautious macro signals continuing to pressure Bitcoin, while identifying market stabilization and renewed capital inflows as key indicators to watch.

    Ethereum Adds $825 Million to Expiry Event

    Around 433,000 Ethereum options contracts also expire Friday, with a notional value near $825 million. The contracts carry a 0.59 put/call ratio and a $1,800 max-pain level. Ether has traded within a narrow range near $1,900 during recent sessions. Total Ethereum options open interest across exchanges remains near $5.4 billion.

    Together, the Bitcoin and Ethereum expiries reach approximately $10.4 billion. Meanwhile, the broader crypto market returned to about $2.3 trillion after losing nearly $25 billion during the week.

    The weekly retreat followed the Federal Reserve’s decision to hold interest rates steady and the resumption of military action between the United States and Iran.

    Market participants will watch settlement flows, capital movement, and price stability for signs of renewed volatility in the days ahead.

  • Christopher Nolan’s ‘The Odyssey’ Ignites a Player Surge in Assassin’s Creed Odyssey

    Christopher Nolan’s ‘The Odyssey’ Ignites a Player Surge in Assassin’s Creed Odyssey

    Christopher Nolan’s latest epic, The Odyssey, is not only captivating moviegoers but also breathing new life into a classic video game. Since the film’s release, Ubisoft’s 2018 RPG Assassin’s Creed Odyssey has seen a remarkable resurgence in player activity across all platforms, with the most dramatic spike on Xbox.

    According to analytics firm Alinea Analytics, the Xbox player count jumped by 134%, climbing from 36,000 to 84,000 daily active users. Analyst Rhys Elliot noted, “The film didn’t make millions buy an eight-year-old game, but it got a massive cohort playing it again. That data gives Ubisoft great ammunition for an eventual AC Odyssey Resynced.”

    This trend echoes similar cross-media boosts seen in recent years, such as Netflix’s Cyberpunk: Edgerunners reviving Cyberpunk 2077, and the HBO series The Last of Us driving players back to the original game. The shared setting of ancient Greece and Homer’s story in both the film and the game appears to be the key driver, prompting both new players and returning veterans to explore the world of Assassin’s Creed Odyssey.

    For Ubisoft, this renewed interest arrives without any new expansion or major update—a testament to the power of quality film adaptations in boosting legacy game titles.

  • Apple’s Q3 Earnings Beat Estimates: Tim Cook Highlights AI Investments and iPhone Growth Amid Supply Concerns

    Apple’s Q3 Earnings Beat Estimates: Tim Cook Highlights AI Investments and iPhone Growth Amid Supply Concerns

    Apple reported stronger-than-expected fiscal third-quarter earnings, driven by record iPhone sales and robust Mac demand. The company posted revenue of $109.42 billion, up 16% year-over-year, and net profit of $29.79 billion. However, a cautious outlook for the upcoming quarter and ongoing supply constraints tempered investor enthusiasm, sparking discussions about Apple’s AI strategy and future growth trajectory.

    Record Quarter Powered by iPhone Demand

    iPhone sales reached an all-time high of $54.25 billion, reflecting strong global demand despite a competitive smartphone market. Mac sales surged nearly 29% as consumers responded positively to the latest product lineup. Apple described the June quarter as its best ever, with double-digit growth across most product lines and geographic regions, beating analysts’ projections by a wide margin.

    Supply Constraints Temper Growth Outlook

    Despite the strong quarter, Apple projected revenue growth of 9% to 11% for the September quarter, below market expectations. CEO Tim Cook attributed the conservative outlook to ongoing shortages of advanced memory components used in Apple-designed chips. The company is working to diversify suppliers, but executives cautioned that component availability could remain a challenge in the near term, leading to a dip in Apple’s share price after the earnings release.

    Services Slow, AI Strategy Under Scrutiny

    Apple’s services division underperformed relative to analyst expectations, generating $30.74 billion in revenue. Weakness in the App Store and growing competition in digital services weighed on the segment. The earnings report also reignited debate about Apple’s artificial intelligence strategy, with investors comparing the company’s pace of AI development to that of competitors who have made significant strides in generative AI. While Apple has rolled out AI-based features across its ecosystem, shareholders want clearer evidence of revenue potential from these investments.

    Cook Highlights Long-Term Confidence

    In what was likely one of his final earnings calls as CEO, Tim Cook reiterated that Apple’s long-term fundamentals remain strong. An expanding user base, consistent customer demand, and a robust innovation pipeline are expected to sustain the company’s competitive advantage. However, the market reaction suggests investors are increasingly focused on Apple’s ability to navigate supply disruptions while keeping pace in the rapidly evolving AI landscape. Balancing hardware growth with emerging technologies will be a central challenge as the company transitions to new leadership.

  • Claude AI Chat Conversations Leak Through Google and Bing Search Indexing

    Claude AI Chat Conversations Leak Through Google and Bing Search Indexing

    A newly uncovered privacy issue has emerged involving Anthropic’s Claude AI, where shared chat links have been discovered in Google and Bing search results. Users reported that public Claude conversations—covering topics such as political advice, legal questions, and personal discussions—could be found through simple search queries, sparking concerns about unintended data exposure.

    The issue came to light via a Reddit post highlighting that certain Claude chat links appeared in search engine results. Claude AI includes a feature allowing users to generate public shareable links for their conversations. While Anthropic stated that it had instructed Google’s crawler not to index these pages through a robots.txt file, experts note that this method alone does not guarantee exclusion from search listings.

    A spokesperson for Claude AI explained: “Shareable links are not guessable or discoverable unless people choose to share them themselves. When someone shares a conversation, they are making that content publicly accessible, and like other public web content, it may be archived by third-party services.” Both Google and Bing have emphasized that website operators should implement a noindex tag to prevent pages from appearing in search results. Analysts observed that the affected Claude chat pages lacked this additional security measure.

    Glenn Gabe, an SEO and AI search consultant at G-Squared Interactive, commented: “If you block Google or Bing from crawling your content, they can still index those URLs, just without crawling the content.” This suggests that even noindex directives may not fully prevent chat leaks if the URLs are publicly accessible.

    How Search Engines Indexed the Chats

    Search engines continuously scan public websites to discover new pages—a process called indexing. Once indexed, a page can appear in search results for relevant queries. Website owners can use tools like robots.txt or noindex tags to block indexing, but if these protections are missing, public links can be added to search results. This scenario unfolded with some shared Claude chat pages before Anthropic implemented changes.

    This incident underscores the importance of robust privacy controls for AI chat platforms and the need for users to be cautious when making conversations publicly accessible.

  • Top Career Lessons from Felicity Blunt: Trust Your Judgment, Edit Ruthlessly, and Stay Curious

    Top Career Lessons from Felicity Blunt: Trust Your Judgment, Edit Ruthlessly, and Stay Curious

    Careers are rarely defined by one big decision. They are shaped by the standards professionals apply every day—what they choose, what they reject, and how consistently they improve their work. Felicity Blunt, a literary agent at Curtis Brown, has spent her career making those decisions. In a candid interview with Curtis Brown Creative, she shared practical lessons on judgment, discipline, respect, and curiosity that extend far beyond publishing and remain relevant to professionals in any field.

    Trust Judgment Over Trends

    Blunt has said that early in her career she felt nervous about making the wrong call. Instinct was really all she had. Her rule stayed simple: do not sign a project simply for its apparent scale or for echoing someone else’s success. Following what genuinely interests her became the anchor for every decision that followed. This lesson generalizes well past publishing. The early temptation in most careers is to chase what looks impressive rather than what actually holds attention. Blunt’s approach suggests the opposite path works better: judgment, tested honestly against real interest, tends to outlast trend-watching.

    Build Expertise by Paying Attention

    Her advice to aspiring writers starts somewhere unexpected: keep a notebook. Passing thoughts that feel minor in the moment can turn out to matter later, and memory fades faster than most people expect. What gets written down carries a permanence that memory does not. This habit extends far beyond writing. Professionals who make a point of recording what they notice—whether it is a client’s offhand comment, a recurring pattern in feedback, or a detail others overlook—build a valuable collection of insights they can draw on to make better decisions and develop sharper thinking over time. Attention that goes uncaptured tends to disappear. Over time, these small observations turn into experiences that others cannot easily copy.

    Great Work Comes Through Revision

    Nowhere is Blunt more specific than on editing. Her instruction: edit exhaustively, interrogate every line, and do it on a hard copy. Reading on paper reveals what a screen tends to hide. She also recommends stepping away from a piece before returning to it, since distance often clarifies what closeness obscures. The same principle holds outside publishing. A pitch, a report, or a strategy document—none of these are finished after one pass. A first draft is only a starting position. Reviewing work in a different format, or after a deliberate pause, tends to surface flaws that momentum conceals. Iteration, not raw talent, produces most of the quality readers or clients actually notice.

    Respect Makes Collaboration Stronger

    On disagreement, Blunt is direct. Do not avoid it, but always extend the other side respect, even while holding firm on a position. That respect keeps collaboration possible once the disagreement settles. In editorial work, this matters daily. Agents, editors, and authors constantly navigate hard conversations about what a manuscript still needs. The same tension shows up in almost any collaborative career. Holding a standard does not require treating a relationship as expendable. People remember how a disagreement was handled long after they forget what it was about. Productive feedback depends on challenging ideas without making the exchange personal.

    Build a Reputation That Lasts

    Blunt also describes herself as wary of trends. She would rather help a writer become distinct than mold them to whatever the market currently rewards. Careers built mainly around trends often struggle to build a distinct identity, while careers built on steady standards tend to earn lasting trust. Reputation compounds through repeated quality, not isolated wins.

    Stay Curious Throughout Your Career

    Her most memorable line may be the simplest. “Stop looking at the phone.” A head kept down constantly observes nothing. In an industry that depends on noticing what feels fresh in the world, constant reaction leaves little space for real perception. Professionals who keep observing their industries, their customers, and the world outside their desk tend to adapt naturally when circumstances shift, since their thinking moves before events force it to.

    Judgment sets the direction. Observation and revision build the craft. Respect and consistency build the reputation. Curiosity keeps all of it alive over decades rather than years. Blunt’s advice, drawn from one interview about a career built inside publishing, resists easy motivational packaging. It rewards professionals willing to slow down, notice more, and let quality accumulate quietly instead of chasing visibility for its own sake, one habit at a time.

  • Reddit for Beginners: How to Navigate Subreddits, Feeds, and Communities

    Reddit for Beginners: How to Navigate Subreddits, Feeds, and Communities

    Reddit is an online platform where people discuss topics, share ideas, ask questions, and share content with others. The platform has thousands of separate spaces called subreddits. Each subreddit focuses on a specific subject, such as technology, movies, games, books, fitness, travel, news, or personal interests.

    Reddit works through posts and comments. A person can create a post inside a subreddit, and other members can reply with comments. Members can vote on posts and comments with upvotes or downvotes. Popular posts often appear higher on pages, while less useful posts may move lower.

    A Reddit account gives access to communities, saved posts, personal feeds, and discussions. A profile also helps track activity across the platform. Reddit does not work like a typical social media site that focuses only on friends or personal updates. The main focus stays on topics, discussions, and shared interests.

    Understanding Subreddits

    Subreddits are the fundamental components of Reddit. Each subreddit has its own topic, rules, style, and community. The prefix ‘r/’ is used in the name of a subreddit, such as r/books that discuss books or r/technology that focuses on technology.

    Moderators help define each subreddit by enforcing its rules and managing discussions. In particular, moderators form rules, eliminate inappropriate messages, and control discussions. The set of rules is different for each subreddit. One community may accept casual posts, but another could require very thorough answers.

    Before writing a post or comment, it is a good idea to read the rules of the respective subreddit. Understanding the community’s expectations can prevent mistakes and increase enjoyment of using Reddit.

    Finding the Right Communities

    Reddit offers communities for almost every interest. The search bar helps find subreddits through keywords. A person who likes photography can search for photography groups. Someone who enjoys cooking can find recipe communities, food discussions, and kitchen advice.

    A good way to start involves joining a few communities instead of too many at once. A smaller list makes the home feed more useful and easier to manage. Over time, more subreddits can join the account as new interests appear.

    Popular communities often have large member numbers, while smaller communities may offer more focused discussions. Both types have value. Large groups provide many opinions, while smaller groups often create closer conversations.

    Exploring Reddit Feeds

    Reddit offers different feeds that show posts from selected communities. The home feed displays content from joined subreddits. The popular feed shows posts that receive attention from many Reddit users across different communities.

    The latest feed shows newer posts first. The best feed highlights posts with strong reactions from members. These options help users find different types of content based on personal interests.

    A useful feed depends on the communities selected. If an account joins many unrelated subreddits, the home page may feel confusing. A balanced selection creates a cleaner experience with more relevant posts.

    How Posts, Comments, and Votes Work

    A discussion on Reddit basically starts with a post. The post can either contain text, a question, an image or link, or even something else. Members can then reply to the post with comments and start a conversation around the post. Votes are used by the members of Reddit to give importance to the useful content contributions. Upvoting means that the member supports the post/comment, while downvoting means that the member disagrees or does not attach much importance to it. The system, in a way, organizes the content, even though it does not accurately reflect the quality of posts.

    Comments are often the real source of information on Reddit. There are many discussions where you will find information about the topic, the pros and cons, the personal experience of people, advice given by them, etc. Rather than reading the post itself, it is usually better to go through comments.

    Reddit Etiquette and Good Practices

    Reddit features a unique cultural distinctiveness that promotes helpful communication and respect for other people’s views. A good Reddit member needs to read the discussions attentively, to keep the community rules, and to provide useful input.

    Simple replies and comments that are of little value are often neglected. On the contrary, detailed comments supported with facts, examples, and personal experience are much more engaging. Reddit has a karma system. Karma is the total amount of upvotes that the user gets for his or her comments and posts.

    Staying Safe on Reddit

    Reddit offers open discussions, but careful online habits remain important. Personal details such as private addresses, phone numbers, or sensitive information should not appear in public posts.

    Different communities have different levels of trust. Checking sources, reading multiple opinions, and avoiding suspicious links can help create a safer experience. Reddit can provide valuable information, but every post needs careful judgment.

    Building a Better Reddit Experience

    Reddit becomes more useful when members explore topics that match their interests. The platform offers knowledge, entertainment, advice, and conversations from people around the world.

    A beginner can start with a few trusted subreddits, learn community rules, and take part in discussions at a comfortable pace. With time, Reddit becomes a place where people discover new ideas, exchange knowledge, and connect through shared interests.
