Commit To Buy Sourcefire At $37.50, Earn 13.9%

Investors considering a purchase of Sourcefire Inc (FIRE) shares, but tentative about paying the going market price of $53.40/share, might benefit from considering selling puts among the alternative strategies at their disposal. One interesting put contract in particular, is the January 2015 put at the $37.50 strike, which has a bid at the time of this writing of $5.20. Collecting that bid as the premium represents a 13.9% return against the $37.50 commitment, or a 8.7% annualized rate of return (at Stock Options Channel we call this the YieldBoost).

Selling a put does not give an investor access to FIRE's upside potential the way owning shares would, because the put seller only ends up owning shares in the scenario where the contract is exercised. And the person on the other side of the contract would only benefit from exercising at the $37.50 strike if doing so produced a better outcome than selling at the going market price. ( Do options carry counterparty risk? This and six other common options myths debunked). So unless Sourcefire Inc sees its shares decline 29.6% and the contract is exercised (resulting in a cost basis of $32.30 per share before broker commissions, subtracting the $5.20 from $37.50), the only upside to the put seller is from collecting that premium for the 8.7% annualized rate of return.

The chart above, and the stock's historical volatility, can be a helpful guide in combination with fundamental analysis to judge whether selling the January 2015 put at the $37.50 strike for the 8.7% annualized rate of return represents good reward for the risks. We calculate the trailing twelve month volatility for Sourcefire Inc (considering the last 249 trading day closing values as well as today's price of $53.40) to be 50%.

In mid-afternoon trading on Friday, the put volume among S&P 500 components was 745,781 contracts, with call volume at 745,781, for a put:call ratio of 0.75 so far for the day, which is above normal compared to the long-term median put:call ratio of .65. In other words, if we look at the number of call buyers and then use the long-term median to project the number of put buyers we'd expect to see, we're actually seeing more put buyers than expected out there in options trading so far today.
