Turning to the other side of the option chain, we highlight one call contract of particular interest for the July expiration, for shareholders of 3M Co ( MMM) looking to boost their income beyond the stock's 2.4% annualized dividend yield. Selling the covered call at the $143 strike and collecting the premium based on the $1.44 bid, annualizes to an additional 10% rate of return against the current stock price (this is what we at Stock Options Channel refer to as the YieldBoost), for a total of 12.5% annualized rate in the scenario where the stock is not called away. Any upside above $143 would be lost if the stock rises there and is called away, but MMM shares would have to climb 1.1% from current levels for that to happen, meaning that in the scenario where the stock is called, the shareholder has earned a 2.1% return from this trading level, in addition to any dividends collected before the stock was called. The chart below shows the trailing twelve month trading history for 3M Co, highlighting in green where the $140 strike is located relative to that history, and highlighting the $143 strike in red: The chart above, and the stock's historical volatility, can be a helpful guide in combination with fundamental analysis to judge whether selling the July put or call options highlighted in this article deliver a rate of return that represents good reward for the risks.
