In the following video, Fool analysts Charly Travers and Austin Smith talk about some of the reasons Microsoft investors might consider selling the stock.

Even the most die-hard Microsoft bull has to acknowledge that the company's era of computing dominance is over, Charly says. That's due mostly to the shift to mobile computing and the success of rivals Apple and Google in that growing market.

With Windows 8, Microsoft is attempting to get into the game. Investors will know within a quarter or two how well the company is gaining traction on the mobile front, Charly says.

Microsoft may have a strong balance sheet and sell at a low P/E, but without a catalyst to move the stock forward, Microsoft's moat could continue to erode and drag the share price down. Austin says.

If it can't gain traction on the mobile front in coming quarters, investors may want to consider selling the stock.
