Walgreen (NASDAQ:WBA) is a selection for the real-money Inflation-Protected Income Growth portfolio. In this brief video, portfolio manager Chuck Saletta offers up the one reason he's considering selling the stock despite its substantial gain since he bought those shares a little more than a year ago.

Walgreen's meteoric stock-price increase means the company has rocketed past a reasonable fair-value estimate, though its balance sheet, dividends, and prospects remain strong. As a result, if its stock price passes $72 per share before Walgreen's next earnings announcement, he'll consider selling. Otherwise, he plans to hold through the earnings announcement and re-evaluate to see whether it drives changes to that fair-value estimate.
