Jamie Dimon warned investors to get ready for more wild rides like the one that upended markets at the end of last year.
“The fourth quarter of 2018 might be a harbinger of things to come,” the chief executive officer of JPMorgan Chase & Co. said Thursday in his 51-page annual letter to shareholders. Dimon cited a raft of issues driving the more pessimistic outlook, including uncertainty about the Federal Reserve’s interest-rate shifts, Germany’s economic slowdown, Brexit and the U.S.-China trade spat.
