NEW YORK, Sept 10 (Reuters) - Short interest on the New York Stock Exchange rose 2.5 percent in late August, the exchange said on Thursday.
As of Aug. 31, short interest rose to about 22.107 billion shares, compared with 21.558 billion shares as of Aug. 14.
Investors who sell securities short borrow shares and then sell them, expecting the stock to fall so they can buy the shares back at the lower price, return them to the lender and pocket the difference.
