Stock Market Today: May 12, 2026 — Hot CPI, Oil Spike Rattle Tech

What Moved the Stock Market May 12, 2026

A hot inflation print and a fresh leg higher in crude oil dominated the tape. April CPI rose 0.6% month-over-month and 3.8% year-over-year — one tenth above consensus and the highest annual headline reading since May 2023 — and President Trump's dismissal of Iran's latest peace proposal sent WTI back above $100. Defensive and energy-linked names absorbed flows out of mega-cap semiconductors, leaving the indexes split rather than uniformly red.

The S&P 500 closed at 7,400.96, down 11.85 points or 0.16%. The Nasdaq Composite fell 186 points, or 0.71%, to 26,088.20 — surrendering Monday's record-high handoff. The Dow Jones Industrial Average closed 56.09 points higher at 49,760.56, a 0.11% gain carried by industrials and health care. The Russell 2000 lagged again, slipping 26.97 points or 0.94% to 2,843.67 as small caps wore the brunt of the back-up in yields.

May 12, 2026 Volatility, Yields, and Commodities

The VIX closed at 17.99, down 0.39 (-2.12%) after spiking intraday on the CPI shock and easing as equities clawed back losses into the bell. The 10-year Treasury yield rose roughly 4 basis points to 4.42%, a one-week high, as traders pared 2026 rate-cut bets after the inflation print. The U.S. Dollar Index (DXY) firmed 0.38% to 98.33.

WTI crude settled at $101.87 a barrel, up 3.87% on the day, after the White House described the U.S.–Iran ceasefire as on "massive life support." Gold was the notable casualty of the firmer dollar, falling 1.22% to $4,678.10 per ounce. Bitcoin slipped under $81,000.

May 12, 2026 Sector Performance

Energy ran higher in lockstep with crude, while semiconductors led tech lower. Defensives and industrials picked up the slack.

May 12, 2026 Biggest Stock Movers

QCOM -11%. Qualcomm was the day's worst large-cap performer after the company flagged softening handset OEM order patterns into the back half and cooling automotive design-win momentum. The post-Monday-high reset in memory and mobile semis sent ripples through the entire chip complex.

WEN +18%. Wendy's ripped higher after the Financial Times reported that Nelson Peltz's Trian Fund Management is in talks to raise capital for a take-private bid. The move came alongside a Q1 beat: adjusted EPS of $0.12 and revenue of $540.6M, both ahead of consensus.

UAA -14%. Under Armour cratered after its FY2027 adjusted EPS outlook landed well below the Street, with management citing tariff pass-through pressure on input costs and softer North American wholesale orders.

CAT +3.2%. Caterpillar closed at $926.79, leading the Dow on a fresh round of upbeat construction and mining capex commentary. The name has become the cleanest proxy for the U.S. infrastructure-spending narrative, and it pulled peer DE along with it.

MU -3.6%. Micron gave back a chunk of Monday's record-high move as profit-taking ran through HBM-exposed memory names. Peers WDC (-3%) and SNDK (-4%) traded in sympathy, while AMD finished off 2%.

Macro & Policy: April CPI Reset the Disinflation Story

The April CPI was the single biggest catalyst this week. Headline inflation accelerated to 3.8% year-over-year from 3.3% in March, with energy prices up 3.8% on the month — accounting for more than 40% of the headline gain — and apparel up 0.6% as tariff pass-through showed up clearly in the data. Airline fares jumped 2.8% on the month, putting the trailing 12-month gain at 20.7%. Core CPI rose 0.4% month-over-month and 2.8% year-over-year, both a tenth above consensus, with the monthly print the firmest since January 2025.

The release landed against an active leadership transition at the Federal Reserve. Chair Powell's term ends Friday, May 15, with the full Senate expected to vote on Kevin Warsh's nomination to succeed him in the coming days. Fed funds futures repriced a September cut to roughly a coin flip from near-certain a week ago.

May 12, 2026 Earnings Highlights

Honeywell was the cleanest beat of the day, posting Q1 results that topped expectations and reaffirming its 2026 outlook. The company also announced the sale of its Warehouse and Workflow Solutions unit as part of its ongoing portfolio simplification. Shares closed +3.23% at $219.11.

Wendy's delivered Q1 adjusted EPS of $0.12 on revenue of $540.6M, both ahead of consensus, with same-store sales returning to positive territory in the U.S. The take-private headline turbocharged the reaction.

Under Armour was the day's earnings disaster — fiscal Q4 EPS came in roughly in line, but the FY2027 outlook called for high-single-digit revenue declines in North America and a sharp gross-margin contraction tied to tariffs.

What to Watch Tomorrow — Wednesday, May 13, 2026

• Cisco earnings after the close — consensus EPS around $0.92 on revenue near $14B. The cleanest tell on AI-related enterprise networking capex this week.
• Alibaba earnings before the open — Q4 FY2026, consensus revenue near $36B. Analyst revisions have skewed negative, so the bar is low but headline risk is high.
• April Producer Price Index (PPI) at 8:30 a.m. ET — the second leg of this week's inflation data. A hot print on top of Tuesday's CPI would force a further repricing of the Fed path.
• Senate floor activity on the Warsh Fed-chair nomination — any movement here can hit the long end of the curve and rate-sensitive equities directly.
