Quick Hits

• Berkshire's post-Buffett hand shows itself. Greg Abel's first closely-watched 13F season as successor shows the conglomerate sold over 50% of its Nucor (NUE) stake and piled into an AI stock that Bill Ackman had just exited — alongside three other new positions beyond Alphabet (GOOGL), per Motley Fool.
• Tesla (TSLA) has lost its $1.5 trillion market cap, down almost 24% in 2026 while the S&P 500 is up nearly 13.8% — one of the clearest casualties of this year's rotation out of mega-cap leadership.
• Viking Holdings (VIK) beat on both lines: non-GAAP EPS of $1.31 topped consensus by $0.07, and revenue of $2.19B beat by $50M.
• David Tepper timed the top. Appaloosa's second-quarter 13F shows the fund sold its entire Sandisk (SNDK) stake in the same quarter the stock peaked at $2,354.39 on June 22.
• XRP broke below $1 for the first time since 2024, bringing its 2026 decline to nearly 50%.

Markets Overview

The defining trade of 2026 keeps widening: the Magnificent Seven are collectively lagging the S&P 500 year to date, while small-caps, international, value, and dividend stocks are all outperforming, according to Motley Fool. The index backdrop remains solid — the S&P 500 up 13% YTD, the Nasdaq Composite up 15% — and MarketWatch puts a 49% probability on the Dow delivering a fourth consecutive year of double-digit gains.

Earnings Reports

• Apple (AAPL): Tim Cook's final earnings call as CEO coincided with the week Apple crossed a $5 trillion market cap. Shares rose roughly 2,180% over his tenure (since 2011, as of Aug. 17), and the focus now shifts to execution under his successor.
• Netflix (NFLX): A 43% drawdown from its high — something that has happened only twice in the last 15 years — has the stock at 21x forward earnings; Motley Fool compares that multiple to the prior two episodes.
• Nvidia (NVDA): Up 15% since July 29, and one Fool analyst argues a 37.5 trailing P/E won't look overvalued by 2028.

Fed & Economic Data

• Kevin Warsh is three months into the chairmanship (sworn in May 22 as Jerome Powell's successor), and Motley Fool argues he has inherited his predecessor's "Trump problem" with no easy fix — keep an eye on Fed independence as a simmering macro risk.
• Cash still pays: Interactive Brokers (IBKR) is holding $930 billion of customer money, and Fool breaks down what that earns at today's rates — a useful marker of where short-term yields actually sit.

Hot Sectors

• The AI memory/hardware complex is where the volatility lives. Micron (MU) is up nearly 240% and Sandisk (SNDK) touched $2,354.39 in June; r/stocks traders are now flagging rapidly rising volatility across memory names as a pattern that has historically preceded bubble breaks.
• The capex question deepens. A Wall Street Journal analysis circulating on r/stocks argues Big Tech's AI spending is $3 trillion higher than it appears due to off-balance-sheet commitments from the hyperscalers — a direct challenge to the infrastructure-spending narrative underpinning tech valuations.
• Cerebras (CBRS) has been a post-IPO bust, per MarketWatch, and its comeback hinges on a new chip built to outpace GPUs as AI agents proliferate. The stock got a lift from an expanded OpenAI partnership to accelerate the "Ultrafast" mode of GPT-5.6 Sol.

Stock News

• Palantir (PLTR): CEO Alex Karp delivered good news and Wall Street is saying buy — though the retail favorite has essentially moved sideways this year despite the AI boom.
• Hims & Hers (HIMS) filed a cluster of insider disposals dated Aug. 14: CEO Andrew Dudum (78,859 shares), CTO Mohamed Elshenawy (95,798 shares at $28.15, roughly $2.7M), COO Michael Chi (47,702 shares), plus the policy and medical chiefs — several flagged as non-discretionary — even as the company pushes into testosterone and peptides.
• Unitree Robotics drew a bullish Mizuho call right out of the IPO gate.
• UL Solutions (ULS) declared a $0.145 dividend.
• Verizon (VZ): A 5.8% dividend yield has Fool asking whether it's a buying opportunity.
• IPO hangover check: SpaceX (SPCX) completed the largest U.S. IPO on record in June, but Fool argues a quieter name beats SpaceX, Micron, and Sandisk for long-term investors.

Market Analysis

• The valuation debate is the loudest it's been all year. With the S&P near record highs and forward P/E just above 20, r/investing is split on whether 8%+ perpetual growth is realistic; Motley Fool counters that investors who follow one historical rule through inevitable crashes come out ahead.
• Retail forums skew cautious. One widely-discussed r/stocks thread argues AI capex has lulled investors into complacency while the next financial crisis brews — the mechanics being that capex spending drives debt issuance, which in turn pressures the bond market.
• The yen carry trade is back in focus, with a detailed r/investing write-up arguing the trade is "cooked" as Japan's rate dynamics undermine the strategy.
• Safe havens are stirring again: gold and silver are both rising after hitting record levels earlier this year, and Fool weighs which metal has more upside.
• The scale race continues: only Nvidia, Apple, and Alphabet sit above $4 trillion in market value, and Motley Fool predicts three more AI names join the club by 2028.

What to watch: follow-on repositioning after Berkshire's 13F hits the tape, Cerebras' new chip as the first real test of the non-GPU thesis, and Apple's opening chapter under new leadership after Cook's farewell quarter.
