Below we highlight the individual stocks in the Russell 1,000 with the highest and lowest short interest as a percentage of float. As shown, NutriSystem (NTRI) tops the list with a short interest of 73% of its float. NTRI's short interest is much higher than any other stock in the Russell 1,000, with CROX being the second highest at 44%. Each of these stocks are down nearly 50% this year, so the shorts are definitely winning.
With short interest so high, any good news from these companies should send shares sharply higher as shorts buy back shares to cover their positions. Panera (PNRA) ranks third on the list at 35%, but it is up 22% on the year. Other notables on the list of most heavily shorted stocks include LEN, KBH, CC, SHLD and RSH. Big Lots (BIG) is also on the list of stocks with high short interest, and it is the best performing stock in the S&P 500 year to date.
