Markets this year are roiling, uncertainty abounds and the U.S. government has had to step in to rescue two large American banks in recent days.

It’s up more than 60% this year, after dipping to a three-year low following the collapse of crypto trading firm FTX in November. AP explains what happened, and what may be ahead.
