NEW YORK, April 25 (Reuters) - Short interest on the New York Stock Exchange rose 1.3 percent in mid-April, the exchange said on Friday.
As of April 15, short interest rose to about 18.114 billion shares, compared with 17.886 billion shares as of March 31.
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.
