According to CoinMeta, the Nasdaq 100 index fell by 4.5% at one point during trading on Friday, dropping more than 10% from its recent high, facing its third technical correction of the year.

Markets have begun to re-evaluate the return on investment for AI, and the increased financing needs of tech companies have also exacerbated sector volatility.

The last time the U.S. stock market experienced three or more 10% fluctuations within a year was in 2022.
