The US stock market's five consecutive months of upward momentum abruptly came to an end at the beginning of the second quarter. The resurgence of inflation concerns and the Federal Reserve's delayed expectation of interest rate cuts have hit risk appetite.

In contrast, small cap stocks are still struggling due to the uncertainty of the economic outlook.
