Realty Income's dividend yield spread relative to the REIT sector is at a multi-year peak. Click here to find out why I rate ...

Earnings Per Share (TTM) A company's net income ... the total market value of a company. Market Cap is calculated by multiplying the number of shares outstanding by the stock's price.

And when a stock's fair value is higher than its current market price ... undervalued. Realty Income Corp. is graded D on this front, indicating that it is trading at a premium to its peers.

If Realty Income stays below 55, the investor can continue selling call options until the shares get called away.
