MW These stocks in the S&P 500 are rising the most after Trump's cease-fire announcement

By Philip van Doorn and Tomi Kilgore

Travel-related companies and semiconductor manufacturers dominated the list of top U.S. stock performers early Wednesday

These are three of the best-performing stocks in the S&P 500 early on April 8, as investors reacted to President Trump's announcement of a cease-fire with Iran.

Investors were euphoric early on Wednesday after President Donald Trump's announcement Tuesday night of a two-week cease-fire between the U.S., Israel and Iran.

The resulting drop in crude-oil prices also provided some hope that tamer inflation will give the Federal Reserve room to be more open to lowering interest rates, or at least not to raise them, which could ease worries about a weakening labor market.

The Dow Jones Industrial Average DJIA was up 1,266 points, or 2.7%, in early trading, at 47,850.15. The S&P 500 index SPX was up 2.3%, with 73% of component stocks showing gains. There were 15 stocks in the S&P 500 showing gains of 10% or more, and 99 were up 5% or more. All price changes in this article exclude dividends.

Continuous front-month contracts for West Texas Intermediate crude oil (CL00) on the New York Mercantile Exchange were down 18% to $92.60 a barrel early on Wednesday, but they were still up 61% from $57.43 at the end of 2025.

Quick reactions to the cease-fire:

-- What the market is pricing for Fed and global central-bank interest rates after the cease-fire

Travel-related stocks were well-represented on the list of early winners on Wednesday. Falling fuel costs provide a boost to the bottom lines of airlines and cruise operators, while lower gasoline prices also put more money into the pockets of potential travelers, especially those who may be on the fence about booking a trip due to cost constraints.

Delta $(DAL)$ didn't make the top 20 list, but its stock was still up 7.3% early Wednesday. The carrier was able to soothe investors by explaining how it had planned ahead to withstand fuel-price increases.

Shares of UnitedHealth Group $(UNH)$ were up 10.3% Wednesday, following a 9.4% gain on Tuesday, as investors continued to react to the Centers for Medicare & Medicaid Services' announcement of a large increase in the expected Medicare Advantage reimbursement rate for 2027.

Humana $(HUM)$ just missed the top 20 list with a 9.2% gain early on Wednesday.
