Stocks were mixed on Thursday, with the S&P 500 Index rising slightly higher while tech-heavy Nasdaq Composite and Dow Jones Industrial Average fell lower, as Wall Street finished out a holiday-shortened week with lingering tariff concerns. The Dow was also pulled lower due to a warning from UnitedHealth Group (UNH  ) over the health of the insurance industry after its earnings miss.

Here's how the market settled to close out the week:

S&P 500 Index (SPY  ): +0.13% or +7.00 points to 5,282.70

Dow Jones Industrial Average (DIA  ): -1.33% or -527.16 points to 39,142.23

Nasdaq Composite Index (QQQ  ): -0.13% or -20.71 points to 16,286.45

Shares of UnitedHealth plunged over 20% on Thursday after the healthcare giant cut its annual profit outlook due to higher-than-expected Medicare plan cuts, signaling potential headwinds for the insurance industry. UnitedHealth is the largest Dow component by weight.

The company said increased demand for outpatient and physician services in its Medicare Advantage plans are topping its planned increase for the year; the healthcare insurance industry has been impacted by rising costs since mid-2023 for services under Medicare plans for older adults and individuals with disabilities.

United now expects 2025 adjusted profit per share to range from $26 to $26.50, compared with its prior guidance range of $29.50 to $30 per share.

Investor sentiment dipped on Wednesday after Federal Reserve Chair Jerome Powell warned that President Donald Trump's tariff policies present a "challenging scenario," for policymakers as he expects the duties to increase inflation and slow economic growth.

Trump responded to Powell's remarks on Thursday, saying that his "termination cannot come fast enough," in a post on his social media platfrom Truth Social, adding to his calls for Powell to either lower interest rates or vacate his position. Trump continued that Powell is "always TOO LATE AND WRONG," and he "should have lowered Interest Rates, like the [European Central Bank], long ago," referencing the ECB's latest rate cut on Thursday.

The ECB warned following its widely anticipated 25-basis-point rate cut, bringing its deposit facility rate to 2.25%, that global tariff policies has impacted the eurozone's economic growth outlooks.

"Increased uncertainty is likely to reduce confidence among households and firms, and the adverse and volatile market response to the trade tensions is likely to have a tightening impact on fanciaing conditions," the ECB said in a statement.

Even with Thursday's small gains for the S&P 500, the index fell alongside the broader market for the week, posting a 1.5% decline. The Dow and Nasdaq each also were more than 2% lower for the week, as nearly all sectors and industries have been impacted by rising uncertainty and negative growth outlooks spurred on by Trump's tariff policies initially released, and then since amended, on April 2.

Markets will close in observance of Good Friday in the United States and will be open for normal trading hours on Monday.

Eli Lilly (LLY  ) said Thursday its daily obesity pill met the company's goals in the first of several late-stage clinical trials. The drug is developed to target patients with Type 2 diabetes, and has been observed to lower both their blood sugar and body weight while having a safety profile comparable to popular GLP-1 weight loss injections.

CEO David Ricks said the pill "could be readily manufactured and launched at scale for use by people around the world," according to a release, helping to address supply shortfalls and limited access for patient seen in the emerging weight-loss injection market.
