Wall Street Wrap: How the S&P 500, Dow and Nasdaq Performed
October 21, 2026 | ATN Trade & Finance
US equities closed higher on Wednesday in a broad, tech-led advance, with the Nasdaq outperforming as earnings beats from SpaceX and a string of strong industrial reports lifted sentiment ahead of after-hours results from Tesla and Meta.
The Closing Numbers
The S&P 500 finished at 7,757, up 44.6 points (+0.58%) — its third consecutive positive session. The Dow Jones Industrial Average added 361 points (+0.69%) to close at 52,857. The Nasdaq Composite gained 278 points (+1.05%) to 26,702, while the Russell 2000 added a modest +0.27%, reflecting more cautious sentiment toward smaller-cap names. The VIX dropped to 16.68, down 3.6%, suggesting diminishing near-term fear.
What Drove the Day
Technology led sector gains, with the Technology Select Sector ETF (XLK) rising 1.68%, followed by Industrials (XLI, +0.91%). Defensive sectors that had led recent sessions — Healthcare, Consumer Staples, and Utilities — gave ground on the rotation back into growth. Consumer staples names including Clorox, Conagra, and General Mills fell 1–3%.
The day's standout story was SpaceX (SPCX), which surged +7.79% to $159.31 after reporting Q3 earnings that beat estimates. CEO Elon Musk said a merger between SpaceX and Tesla "would be a good idea," and both companies' boards formed special committees to review the possibility. Tesla (TSLA) rose +3.41% to $386.47 in sympathy before reporting after the close. Super Micro Computer (SMCI) jumped more than 10% intraday after raising its Q1 revenue guidance to $18.5–$19.5 billion, well above prior forecasts. A critical web vulnerability — dubbed "PHP2Shell" — prompted emergency patches and temporary site outages, sending cybersecurity names sharply higher: Zscaler, Cloudflare, CrowdStrike, and Okta each rose 5–7%.
On the industrial side, RTX reported adjusted EPS of $2.26 — up 33% year-over-year — and raised its full-year 2026 outlook, while Northrop Grumman disclosed a $110 billion backlog. The FAA certified the Boeing 737 MAX 10, a long-awaited milestone ahead of Boeing's Q3 report scheduled for October 27.
The Losers
Netflix (NFLX) was the day's most prominent casualty, falling 4–6% after reporting after the close the prior evening. Despite beating on EPS, the company posted its slowest revenue growth in three years and cut its full-year advertising revenue outlook — a signal that the ad-supported tier is growing but not at the pace investors had priced in. AT&T (T) dropped 6% following a mixed Q3 report compounded by investor concern that SpaceX's expanding satellite-based mobile offering threatens its subscriber base. Apple (AAPL) was downgraded to Hold by Loop Capital, which set a $330 price target and cited weakening iPhone demand.
Rates, Commodities, and Crypto
The 10-year Treasury yield ticked up about 3 basis points to 5.145%, sustaining pressure on longer-duration assets. The 2-year yield held near 4.82%. WTI crude settled at approximately $97.15, while Brent was near $108.82. Gold settled at $4,150 (+0.18%). Bitcoin rose more than 2% toward $84,600, and Ethereum gained over 2.5% to top $2,500, with both moves partly attributed to the finalization of the SEC's federal stablecoin rule, which lifted Circle (CRCL) and Coinbase (COIN) by more than 4% each.
What this means: Wednesday's session confirmed that earnings — not macro — is the dominant near-term market driver. The SpaceX-Tesla merger narrative is injecting speculative energy into the AI and space trade, but the underlying story is a market doing reasonably well at 5% 10-year yields: technology hardware, defense, and industrials are delivering. The Fed's October 27–28 meeting and next week's PCE inflation print are the next scheduled catalysts. After-hours results from Tesla, Meta, IBM, and others will set the tone when markets open Thursday.
