US Stock Market Update: Dow Gains 530 Points as Tech Lags

U.S. stocks ended the latest completed trading session mostly higher, with the Dow Jones Industrial Average climbing nearly 530 points as healthcare shares and upbeat corporate earnings helped offset weakness in major technology stocks.

This October 21, 2026 update covers the U.S. market close on Tuesday, October 20. Wednesday's regular Wall Street session has not yet begun, so the figures below are closing results, not live Wednesday prices.

Dow outperforms as the Nasdaq edges lower

The Dow gained 529.85 points, or 1.02%, to finish at 52,495.88. The S&P 500 rose 21.84 points, or 0.28%, to 7,712.57, while the Nasdaq Composite slipped 6.07 points, or 0.02%, to 26,424.82, according to Reuters.

Smaller companies had a stronger session. The Russell 2000 advanced 45.12 points, or 1.7%, to 2,773.42, the Associated Press reported. The contrast with the nearly flat Nasdaq showed that Tuesday's gains extended beyond the large technology companies that often dominate market headlines.

Healthcare leads while technology weighs on returns

Healthcare was the strongest of the S&P 500's 11 major sectors and reached a record high. Eli Lilly was the benchmark's biggest contributor by index points, while UnitedHealth, Merck, Johnson & Johnson and Amgen helped lift the Dow, Reuters reported.

Technology fell 0.3% and was the biggest index-point drag on the S&P 500. Communication services also weakened as Meta Platforms, Alphabet and Netflix declined. Financial stocks, real estate and utilities advanced, highlighting a session in which investors found gains outside the largest growth names.

Oil prices eased after an earlier climb, helping stocks recover from morning weakness. The Associated Press reported that Brent crude retreated below $109 a barrel after approaching $112. That reversal offered some relief, although elevated energy prices remain an important backdrop for company costs and inflation concerns.

Earnings create sharp moves in individual stocks

3M rose 5.8% after lifting its full-year profit outlook, according to Reuters. In its official earnings release, the company reported third-quarter adjusted earnings of $2.50 a share and raised its 2026 adjusted earnings guidance to $9.10–$9.15 a share.

Equifax rallied 11.3% after beating profit expectations, while Hasbro gained 11.2% after raising its full-year outlook. General Motors moved the other way, falling 6.8% as investors weighed pressure from higher commodity costs and lower truck sales, Reuters reported.

After the closing bell, Netflix shares fell 6% following a weaker-than-expected fourth-quarter profit forecast, according to Reuters. That after-hours move is separate from its regular-session decline and is not included in Tuesday's Nasdaq closing figure.

What matters for the next session

The next test is whether strength in healthcare, financials and smaller companies can continue if large technology shares remain under pressure. Fresh earnings reactions and changes in oil prices will offer further clues. Tuesday's results show a market with substantial differences beneath the headline indexes—not a uniform advance across Wall Street.
