BOSTON ( TheStreet) -- Nokia (NOK - Get Report) and Time Warner (TWX - Get Report) had the largest increases in short interest, according to data from the New York Stock Exchange, even as investors turned less bearish.
Short interest, which measures all uncovered short positions in securities, fell during the second half of February, according to the NYSE. Short positions are bets that a stock will fall, where investors borrow shares and sell them at a higher price, hoping to buy the stock back at a lower price to profit on the difference.

During that same period, the S&P 500 fell less than 0.1%. The markets have taken a turn for the worse since as oil and commodity prices continue to soar. Since March 1, the S&P 500 has dropped nearly 2%, including Thursday's 17-point decline, while oil has topped $100 a barrel.
