Consistently, one of the more popular stocks people enter into their stock options watchlist at Stock Options Channel is UnitedHealth Group Inc ( UNH). So this week we highlight one interesting put contract, and one interesting call contract, from the January 2016 expiration for UNH. The put contract our YieldBoost algorithm identified as particularly interesting, is at the $45 strike, which has a bid at the time of this writing of $2.11. Collecting that bid as the premium represents a 4.7% return against the $45 commitment, or a 2.1% annualized rate of return (at Stock Options Channel we call this the YieldBoost).Selling a put does not give an investor access to UNH'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 UnitedHealth Group Inc sees its shares decline 36.4% and the contract is exercised (resulting in a cost basis of $42.89 per share before broker commissions, subtracting the $2.11 from $45), the only upside to the put seller is from collecting that premium for the 2.1% annualized rate of return. Interestingly, that annualized 2.1% figure actually exceeds the 1.6% annualized dividend paid by UnitedHealth Group Inc, based on the current share price of $70.69. 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 fall 36.38% to reach the $45 strike price. Always important when discussing dividends is the fact that, in general, dividend amounts are not always predictable and tend to follow the ups and downs of profitability at each company. In the case of UnitedHealth Group Inc, looking at the dividend history chart for UNH below can help in judging whether the most recent dividend is likely to continue, and in turn whether it is a reasonable expectation to expect a 1.6% annualized dividend yield.
