There seems to be a lot of speculation rushing into Pfizer before they report earnings tomorrow. According to today's option activity it looks like some bullish activity in Pfizer is expected. If you checked out today's option activity in Apple (AAPL) you would have noticed way more calls were traded than puts and the options traders had it right, with a total, what I call, WOWZER quarter from Apple. The gross margins seemed to be a little lighter than expected, but everything else was great! If you read my blog post from this morning, you may have been able to check out my Apple earnings strategy. If not check it out below. I am very happy I opened this position, and think Apple has a shot at trading higher than the after-hours high (roughly 205 a share) with the help of other good earnings reports tomorrow morning. I also sold some 21 strike put options on Texas Instruments (TXN) which I plan on closing tomorrow on implied volatility collapse, and sold 52.50 and 55 strike Caterpillar (CAT) puts which I will also look to close on implied volatility collapse after CAT reports earnings.
