ACOM – Ancestry.com, Inc. – Shares of the online family history resource surged 8.380% in afternoon trading to reach an all-time high of $22.76. The rally in Ancestry’s shares inspired one bullish options investor to purchase a plain-vanilla call spread in the February 2011 contract. It looks like the trader picked up 1,050 now in-the-money calls at the February 2011 $22.5 strike for an average premium of $2.82 each, and sold the same number of calls at the higher February 2011 $30 strike at an average premium of $0.55 a-pop. Net premium paid to establish the bullish spread amounts to $2.27 per contract. Thus, the trader is poised to profit should ACOM’s shares jump 8.8% over today’s high of $22.76 to surpass the average breakeven price of $24.77 by expiration day in February. Maximum potential profits of $5.23 per contract are available to the call-spreader if ACOM’s shares rally 31.8% to exceed $30.00 by February expiration.
