Trade Initial P&L = $(50) Credit This is a Credit Call Butterfly -- that is, I am actually being paid to put on this position (not much, $50 for this size, but still being paid nevertheless.) The position involves buying a Call Butterfly (see above) and selling a Put to fully finance the cost. The key risk is obviously to the downside since we sold the Put. Unless negative data comes out prior to November option expiration -- or the company unexpectedly announces a delay or other negative news -- I would expect Exelixis' share price to remain above $4 given the impending Nov. 29 FDA drug approval decision date. Obviously, I could be wrong. Maximum profit for this trade size is $1,050 if the shares trade to $5 by expiration and this profit tapers off between $4 and $6. (See the P&L diagram.) If the stock trades below $4 by Nov. 17 expiration I will be assigned the shares (1,000 shares for this size trade) and be positioned to either hold into the possible run-up, sell 4.0 strike DEC Calls against the shares (i.e. trade into a covered Call) or simply remove any risk and sell them.
