Synergy Pharmaceuticals

Short interest at Synergy Pharmaceuticals Inc. (NASDAQ: SGYP) totaled over 80.41 million shares by mid-January, after a gain of less than 5 million from on the prior settlement date. Still, that represented a whopping 32.7% of the total float, and it was the fifth consecutive period with more than 70 million. The days to cover shrank from about 14 to less than 12 during the latest period as the average daily volume ended four consecutive periods of decline.

Comcast Corp.’s (NASDAQ: CMCSA) short interest barely grew from in the previous period to more than 64.40 million shares on the most recent settlement date. Still, that was the highest number of shares short since November, and it represented 1.4% of the total float. The days to cover figure slipped a little but remained more than three.
