MannKind (MNKD) is up 2 cents to $8.53 and, in morning trading Wednesday, an investor buys 3000 Feb 10 calls at $1.15, sells 1500 Feb 12.5 calls at 60 cents, and sells 1500 Feb 15 calls at 40 cents. This might be a roll or closing, as open interest is sufficient to cover in all three contracts. On the other hand, it might be a bullish spread ahead of the company’s Jan 16 PDUFA date for rapid acting Insulin, Afresa. (I will discuss this spread a little more in today’s podcast.)
