NEW YORK, Dec 10 (Reuters) - Short interest on the

Nasdaq dipped 0.8% in late November, the exchange said on

Tuesday.

As of Nov. 29, short interest declined to about 13.910

billion shares, compared with 14.018 billion shares as of Nov.

15.

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.

Shorting can also be part of a hedging strategy.
