This week has not been kind to bank stocks.
The SPDR S&P Bank ETF (KBE) was down nearly 4 percent for the week, putting it on track for its worst weekly performance since the week of Jan. 8, when it lost more than 8 percent.
The index also dipped below its 50-day moving average on an intraday basis for the first time since April 8. The stock closed up 0.39 percent at $31.23, above the 50-day moving average of 30.93.
Bank of the Ozarks weighed on the index most, falling nearly 10 percent for the week. On Wednesday, short-selling firm Muddy Waters Capital unveiled a short position on the bank's stock, saying it was making outsized loans relative to its assets and was too heavily concentrated in real estate lending.
