Today’s tickers: HGSI, MDRX, JPM, ESV, FLR & SD HGSI  - Human Genome Sciences, Inc. –  Shares in biotechnology company Human Genome Sciences are down 3.95% this afternoon at $25.23 as of 3:15 pm, but one options trader populating the December contract today is positioning for the stock to rebound ahead of a key FDA decision on its lupus drug treatment, Benlysta. A preliminary FDA review is set for release in one week, while an advisory panel with outside experts is scheduled to provide their input before the FDA provides a final ruling by December 9, 2010. The optimistic options player is well positioned to benefit from a strong rally in the biotech firm’s shares should approval of the lupus treatment become a reality. The trader purchased 5,000 calls at the December $26 strike for a premium of $4.30 each, and sold the same number of calls at the higher December $32 strike at a premium of $1.36 apiece.

Options implied volatility on the biotechnology company is up 12.1% at 141.59% as of 3:30 pm, and will likely continue to ascend ahead of the FDA’s critical ruling.
