Stocks: 6 things to know before the bell

Deutsche Bank is a $2 trillion problem

1. Deutsche Bank slumps: Shares in Germany’s biggest lender slumped about 5% after reports indicated that 10 hedge fund clients are reducing their dealings with the bank. The stock had lost more than 8% in early trade, when it hit a new record low.

The action by the hedge funds, first reported by Bloomberg, is fueling anxiety about the bank’s financial health. Investors also worry whether it can afford a looming U.S. fine for trading in toxic mortgages a decade ago.
