US Stock Market Summary — May 13, 2026

On May 13, the US stock market once again confirmed a "narrow leadership" rally driven by big tech and semiconductors, with the $SPX and $IXIC notching fresh all-time highs. The S&P 500 gained 0.58% to close at 7,444.25, and the Nasdaq Composite rose 1.20% to 26,402.34 — both indexes rewriting their records. The Dow, however, ended slightly lower at -0.14%, making the decoupling between the indices and individual stocks even more pronounced. Early in the session, the April Producer Price Index (PPI) jumped 6.0% year-over-year, the largest gain in four years, signaling a revival of price pressures. That pushed short-term bond yields sharply higher and weighed on financials, but AI and semiconductor heavyweights such as $NVDA, $GOOGL, and $MU attracted solid buying and provided firm support at the index level. On the same day, the US Senate confirmed Kevin Warsh as the next Fed Chair, amplifying views that an "inflation hawk" tone would gain ground, while reports of an upcoming Trump-Xi summit also influenced market sentiment. The Fear & Greed Index climbed a notch to 66 (Greed), indicating that risk appetite remained intact, though some market participants urged caution given the narrowing market breadth.

Technology (`$XLK` +0.94%) and Communication Services (`$XLC` +0.78%) effectively carried the indices on their own, while the semiconductor ETF $SOXX surged 2.38%, reaffirming that AI-related demand remains intact. $MRVL's robust data-center guidance and expectations of HBM price hikes by $MU helped justify the sector's expanding P/E multiples. On the downside, rate-sensitive Utilities (`$XLU` -1.15%), Financials (`$XLF` -1.14%), and Real Estate (`$XLRE` -0.83%) all declined together — a signal that the market repriced toward fewer expected Fed rate cuts in the wake of the PPI shock. In the bond market, long-duration securities wobbled, with $TLT slipping -0.22% and $IEF flat, while short-end $SHY barely moved at +0.04%, producing a mild bear-steepening of the yield curve. In commodities, $USO fell -1.57% as oil weakness persisted, $GLD lost -0.56% on profit-taking, but $SLV rode the industrial-metals tailwind with a +1.02% gain.

Chinese e-commerce heavyweight Alibaba ($BABA) soared +8.18%, posting the largest single-day gain among the top 100 market-cap names, after delivering quarterly results that handily beat consensus on revenue, EPS, and its cloud segment (WSJ). In semiconductors, Marvell Technology ($MRVL) jumped +8.18% on raised data-center revenue guidance, ARM Holdings ($ARM) added +6.43%, and Micron ($MU) gained +4.78% — together driving $SOXX's 2.38% surge. Alphabet ($GOOG +3.97%, $GOOGL +3.94%) advanced in lockstep on optimism around cloud and AI advertising momentum. On the downside, AppLovin ($APP) fell the most at -7.57% amid concerns over ad-tech market share, while Palantir ($PLTR) dropped -4.37% on fears of slowing government contracts. European SaaS bellwether SAP ($SAP) also slid -3.86%, and Home Depot ($HD) declined -2.55% on worries about a soft spring remodeling season (CNBC). Meanwhile, major outlets including BBC reported the formal confirmation of Kevin Warsh as the next Fed Chair, noting that the resulting shift in monetary-policy tone could heighten volatility in rate-sensitive sectors.

> "Warsh's confirmation is a signal the market can't help but read as 'the Fed is shifting back toward an inflation-centric stance.' He has been a consistent critic of pandemic-era monetary policy being too accommodative for too long."

> — Phil Blancato, Chief Market Strategist at OSAIC

> "The 10-year TIPS breakeven inflation rate is approaching the top of its range since 2023. Under a Chair Warsh, any discussion of additional rate cuts poses a significant risk for the bond market."

> — Ryan Swift, Head of US Fixed Income Strategy at BCA Research

> "The real question for the market now is whether Chair Warsh will run policy independently or stand closer to the White House's pressure for rate cuts. Today's PPI print served as another warning shot to everyone about the return of inflationary pressure."

Today, semiconductor and big-tech names flashed multiple short-term overbought signals simultaneously — RSI above 70, upper Bollinger Band breakouts, and stochastic overbought readings — while select financials, consumer staples, and some healthcare stocks triggered technical rebound signals such as RSI oversold conditions and lower Bollinger Band breaches. With market breadth narrowing, selective stock picking on individual signal triggers looks more important than chasing the broader index higher.
