Consistently, one of the more popular stocks people enter into their stock options watchlist at Stock Options Channel is CenturyLink, Inc. ( CTL). So this week we highlight one interesting put contract, and one interesting call contract, from the December expiration for CTL. The put contract our YieldBoost algorithm identified as particularly interesting, is at the $32 strike, which has a bid at the time of this writing of 90 cents. Collecting that bid as the premium represents a 2.8% return against the $32 commitment, or a 16.8% annualized rate of return (at Stock Options Channel we call this the YieldBoost).Selling a put does not give an investor access to CTL'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. So unless CenturyLink, Inc. sees its shares decline 2.7% and the contract is exercised (resulting in a cost basis of $31.10 per share before broker commissions, subtracting the 90 cents from $32), the only upside to the put seller is from collecting that premium for the 16.8% annualized rate of return. Worth considering, is that the annualized 16.8% figure actually exceeds the 6.6% annualized dividend paid by CenturyLink, Inc. by 10.2%, based on the current share price of $32.88. And yet, if an investor was to buy the stock at the going market price in order to collect the dividend, there is greater downside because the stock would have to lose 2.68% to reach the $32 strike price.
