Stock futures fall after Wall Street posts another losing week: Live updates.

The stock market continued its downward trend on Monday morning, with futures for the S&P 500, Nasdaq-100, and Dow Jones Industrial Average all falling. The moves come after each of the three major averages logged a third weekly decline in the last four trading weeks. The S&P 500 closed out Thursday's session higher, but still finished the holiday-shortened week 1.5% lower.

The Dow Jones Industrial Average and Nasdaq Composite both posted their third consecutive losing session, with the former finishing the week with a 2.1% pullback and the latter declining 2.5%. The U.S. stock market was closed on Friday in observance of Good Friday.

The market came under pressure on Thursday from a major sell-off in shares of UnitedHealth, which sank more than 22% after the insurer cut its full-year forecast and posted disappointing quarterly results. The stock's decline weighed heavily on the Dow, which fell 318 points, or 0.81%.

Nvidia also contributed to the market's decline, with its shares falling nearly 3% after the company disclosed a quarterly charge of about $5.5 billion due to controls around exporting its H20 graphics processing units to China and other destinations.

Heightened concern surrounding President Donald Trump's tariffs also weighed on the market. Over the weekend, Chicago Federal Reserve President Austan Goolsbee said in a CBS interview that the tariffs could lead U.S. economic activity to "fall off" by the summer. That follows Fed Chair Jerome Powell expressing concern Wednesday that the president's levies could present difficulty for the central bank in controlling inflation and spurring economic growth.

Despite the uncertainty, some on Wall Street believe the worst could be over. Mike Dickson of Horizon Investments said "perpetual" swings in the market may be less frequent now even if volatility remains. "Continued uncertainty will likely cap stock market valuations and weigh on investors until greater clarity emerges," Dickson said. "Although the tariff situation remains fluid, we believe the roughly 10% daily and weekly market swings seen in recent weeks are behind us for now."

Investors are looking ahead to a key earnings week, with more than 100 S&P 500 companies due to report over the coming days. That includes "Magnificent Seven" names Alphabet and Tesla, as well as others like aerospace giant Boeing. As the market navigates the uncertainty surrounding tariffs and earnings, investors will be keeping a close eye on the market's next move.
