NEW YORK (

TheStreet

Bank of America

(BAC) - Get Report

,

Bank of New York Mellon

(BK) - Get Report

and

Citigroup

(C) - Get Report

saw a sizeable increase in short interest in the second half of November, according to

shortsqueeze.com

.

Bank of New York saw a 17.97% rise in short interest from Nov. 13 to Nov. 30, the latest period for which data is available, the biggest jump among the 10 largest financial stocks held in the

Financial Select Sector SPDR ETF

(XLF) - Get Report

. Bank of America was next, with a 13.13% increase, followed by Citigroup, which saw a 10.86% rise.

Wells Fargo

(WFC) - Get Report

also saw a rise in short interest during the period, though by just 2.32%.

While those large banks were under attack, investment banking-oriented institutions

Goldman Sachs

(GS) - Get Report

and

Morgan Stanley

(MS) - Get Report

got relief from short-sellers over the same period. Goldman short interest dropped by 21.98%, while Morgan Stanley saw a 16.02% drop in short interest.

JPMorgan Chase

(JPM) - Get Report

,

MetLife

(MET) - Get Report

and

U.S. Bancorp

(USB) - Get Report

also saw a drop in outstanding short interest during the period, though not by as much as Morgan Stanley and Goldman.

Contrary to what some might assume, the short-selling numbers do not appear to be merely a reflection of how the big financial companies' shares performed over the period. In fact, shares of Citigroup, Bank of America and Bank of New York outperformed those of Goldman and Morgan Stanley during the two-week period.
