Nvidia shares fell sharply Friday as investors took profits following a week of strong earnings and AI infrastructure optimism. The chipmaker had surged earlier in the week after raising its AI infrastructure outlook, but profit-taking in the semiconductor sector—which saw Intel down 5%, AMD down 3%, and Micron down 4%—dragged the mega-cap lower. The decline reflects broader rotation out of AI names after their recent rally, signaling caution ahead of next week's economic data.
Magnum Ice Cream Company, which owns iconic brands Ben & Jerry's and Cornetto, has attracted acquisition interest from two major buyout firms: Blackstone and Clayton Dubilier & Rice. Magnum shares surged 16% on the news, reflecting investor enthusiasm for a potential deal. The company's portfolio of premium ice cream brands appeals to private equity buyers seeking stable cash flows and pricing power in an inflationary environment. The deal would likely value Magnum in the $10-15B range, making it one of the largest consumer staples M&A transactions in recent years.
Energy stocks have emerged as the S&P 500's surprise outperformers in 2026, defying the AI-dominated narrative of recent years. Valero Energy (refiner) is up 44% YTD, LyondellBasell (petrochemical) is up 66%, and APA Corporation (oil producer) is up 58%—all ranking in the top 25 S&P 500 performers. The common thread: the Iran conflict and Strait of Hormuz blockade have disrupted global oil flows, tightening refining capacity and pushing crack spreads (the profit margin between crude and refined products) to multi-year highs. U.S.-based refiners benefit because they source feedstock domestically, insulating them from supply disruptions. Valero posted Q4 2025 earnings per share of $3.82 (beating consensus by 55 cents) and is expected to grow earnings 32% in 2026. However, all three stocks have pulled back 9-15% from recent highs, potentially offering entry points for investors betting on continued supply disruptions.
SanDisk Corporation (NASDAQ: SNDK) is the S&P 500's best-performing stock YTD, up 160%+, driven by a perfect storm: a global NAND flash shortage colliding with explosive demand for fast, local storage tied to AI at the edge. NAND flash memory is critical for data centers training large language models, as well as for edge devices running AI inference. The shortage has pushed prices higher, improving SanDisk's margins and revenue. The stock remains in a bull flag consolidation, trading just 14% below its all-time high and well above its 50-day moving average, suggesting further upside if the NAND shortage persists.
Moderna shares have surged 80% YTD, driven by pipeline optimism and a timely vaccine opportunity. The company announced that its experimental Alzheimer's drug will advance into Phase 3 trials despite failing to meet the primary endpoint of its Phase 2 trial—a positive signal that the drug showed cognitive benefits. Additionally, Moderna revealed it had already been developing a hantavirus vaccine ahead of a recent outbreak aboard the cruise ship Hondius, positioning the company as a first-mover in a potential new market. However, analysts maintain a consensus Reduce rating with nearly 40% downside implied by their price targets, suggesting the market may be pricing in overly optimistic outcomes.
The U.S.-Iran war entered its 11th week Friday with peace negotiations effectively stalled. President Trump rejected Iran's latest counterproposal, calling it unacceptable and saying the ceasefire was on 'massive life support.' The Strait of Hormuz—through which roughly 20% of global crude oil flows—remains under a dual blockade, with only a handful of tankers managing to transit since the conflict began. The International Energy Agency warned Friday that crude and fuel flows have dropped 4 million barrels per day, and the global oil market could remain severely undersupplied through October even if fighting ends next month. This supply shock is the primary driver of Friday's market selloff: WTI crude surged 4.2% to $105.42, pushing the 10-year Treasury yield up 10 basis points as inflation expectations reset higher. The Fed, which had signaled one rate cut for 2026 in March, is now expected to hold rates at 3.5%-3.75% for the entire year, with some traders pricing in a small chance of a hike by December. The geopolitical stalemate is reshaping market expectations: energy stocks (refiners like Valero up 44% YTD) are outperforming tech, and growth stocks are selling off as the cost of capital rises. Without a breakthrough in negotiations, the energy shock will persist, keeping inflation sticky and the Fed hawkish.
💡 The Strait of Hormuz is a 21-mile-wide chokepoint between Iran and Oman through which roughly 20% of the world's traded oil passes daily. A blockade there disrupts global supply, raises oil prices, and feeds inflation—which forces central banks to keep interest rates higher for longer, pressuring equity valuations.
Cerebras Systems, a startup building custom AI processors, made a stunning market debut Thursday, opening at $350 per share—89% above its $185 IPO price—before settling at $313.25. The company raised $5.55B (with potential for $6.4B if underwriters exercise the full overallotment), making it the largest U.S. tech IPO since Uber in 2019. Cerebras competes directly with Nvidia in the AI chip space, offering a different architecture (wafer-scale chips) designed for large language model training. The IPO's success signals continued investor appetite for AI infrastructure plays, despite Friday's broad tech selloff. However, the stock fell 10% Friday as profit-taking hit the entire semiconductor sector, suggesting the IPO pop may have been driven more by FOMO than fundamental conviction.
💡 Wafer-scale chips are processors built on an entire silicon wafer (rather than cut into smaller dies), allowing more transistors and faster communication between cores—useful for training massive AI models but harder to manufacture at scale.
Cisco Systems posted third-quarter results Thursday that beat analyst expectations and raised its outlook for AI infrastructure revenue, sending shares up 13%. The networking giant is benefiting from enterprise spending on AI data center buildouts, as customers upgrade infrastructure to support large language models. However, the company announced nearly 4,000 job cuts (roughly 8% of workforce), signaling management's view that efficiency gains and automation will offset headcount. The stock's strength Thursday contrasted with Friday's weakness, when semiconductor and AI names broadly sold off on profit-taking and rising rate concerns.
💡 AI infrastructure spending refers to the hardware, networking, and software needed to train and deploy large language models—a multi-billion-dollar market growing 30%+ annually.
Intel and Apple reached a preliminary agreement for Intel to manufacture some of the chips used in Apple devices, according to the Wall Street Journal. This marks a significant win for Intel's foundry business (manufacturing chips for other companies) and a diversification move for Apple, which has relied heavily on TSMC. The deal signals Intel's ability to compete for premium customers despite years of manufacturing challenges. Intel shares jumped 5.7% on the news, though the stock has since pulled back amid broader semiconductor weakness.
💡 A foundry is a chip manufacturing facility that produces chips designed by other companies—a business model that requires cutting-edge equipment and expertise. Intel is investing heavily to compete with TSMC and Samsung in this space.
Bitcoin fell below $80,000 Friday as a $500M long liquidation cascade flushed leverage across major crypto tokens. BTC closed at $78,180 (-1.11%), Ethereum at $2,180 (-1.92%), and Solana at $86.58 (-2.93%), tracking the broader equity selloff and bond market volatility. The liquidations were triggered by the spike in Treasury yields and risk-off sentiment, as traders unwound leveraged positions. However, Solana ETF inflows accelerated to $39.23M this week—the largest since February—suggesting institutional investors are using the dip to accumulate. Morgan Stanley increased its Solana exposure via the Bitwise ETF to $29.9M, signaling growing institutional confidence in the blockchain despite near-term price weakness.
💡 A liquidation cascade occurs when leveraged traders' positions are forcibly closed by exchanges when collateral falls below maintenance levels, creating a feedback loop of selling that can accelerate price declines.
Solana's decentralized finance (DeFi) lending markets have quietly crossed $4B in total deposits, driven by protocols like Kamino and Jupiter. The milestone reflects growing institutional confidence in Solana's infrastructure, especially as the Firedancer validator client—a performance upgrade built by Jump Crypto—rolls out gradually. Firedancer is designed to dramatically increase Solana's throughput and reliability, addressing the network outages that plagued the chain in 2022. The combination of rising deposits and infrastructure improvements is attracting developers and capital, with Solana ranking second only to Ethereum for new developer inflows in 2025.
💡 DeFi (decentralized finance) protocols allow users to lend, borrow, and trade crypto without intermediaries, earning yields on deposits. Kamino and Jupiter are two of Solana's largest DeFi platforms.
Warren Buffett's annual charity lunch auction reached a record $9.1 million this year, with the winning bidder securing a meal with Buffett and NBA star Stephen Curry in Omaha on June 24. The auction, which has raised hundreds of millions for the Glide Foundation over two decades, reflects both Buffett's enduring appeal and the willingness of ultra-wealthy individuals to pay for access to the Berkshire Hathaway CEO. The inclusion of Curry—a global sports icon—likely boosted the final price. The meal represents a rare glimpse into Buffett's world for a select few, though the billionaire's investment philosophy and folksy wisdom are freely available to anyone willing to read his annual shareholder letters.
💡 The Glide Foundation is a San Francisco nonprofit that provides meals, shelter, and services to homeless and low-income individuals. Buffett has donated the proceeds from his annual lunch auction to Glide for over 20 years, raising over $50 million cumulatively.
