Deckers Outdoor (DECK): Investors bought the January 40 calls for $0.80 and sold the January 50 calls for $0.10. Volume was below open interest in the 50s, so they may have rolled down a money-losing position, or could have opened a new bullish spread. DECK fell 0.47 percent to $31.95.
Facebook (FB): Almost 13,000 December 19 puts were bought for $0.65 as investors brace for downside in the so-media stock. FB dropped 0.80 percent to $21.08.
Micron (MU): More than 25,000 January 5 puts were bought for $0.14 and $0.15 but volume was below open interest at the strike. MU rose 2.74 percent to $6.
