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.
