Something that was nearly unthinkable when the year began happened on Thursday. The S & P 500 closed the session in a correction, down more than 10% from a record high set in February, a little more than three weeks ago. The tech-heavy Nasdaq Composite fell deeper into its own correction, down 14% from its all-time high reached in December. Uncertainty around President Donald Trump's tariffs on imports from key trade partners has rattled investor confidence lately, sending stocks lower. On Thursday, Trump threatened to put a 200% levy on Champagne and other European spirits . A correction can add to investor fears of further losses. However, history shows that the S & P 500 tends to rebound after reaching such a grim milestone. Data compiled by Ryan Detrick of the Carson Group shows the S & P 500 averages a 3.1% return one month after entering a correction. The benchmark's return grows to 6.5% and 12% after three and six months, respectively. A year out, the S & P 500 sees an average return of 14.7%, based on data going back to 1950. To be sure, those numbers only account for corrections, not bear markets — which happen when the S & P 500 is down 20% from a recent high. The S & P 500's most recent bear run was in 2022, when the Federal Reserve began to raise interest rates to fight inflation. The index has suffered 11 bear markets since 1950, according to Detrick. That said, Detrick said that another bear market now would be rare. "That would be three bears in 5 years, something we've never seen before. The previous closest three bears ever was 6.9 yrs between 1966 and 1973," he said in a post on X . Elsewhere Friday morning on Wall Street, Barclays upgraded British analytics stock RELX , calling it a potential port in the market storm. "We think RELX offers reliable growth in an environment where relative safe havens may be needed," analyst Nick Dempsey wrote in a Friday note. "The shares are not cheap vs history but not out of line with info services peers."
