It's Time to Book Profits in These 3 Ultra-Popular Stocks

There are a lot of aspects to investing that can be difficult for investors to master. For example, having the patience to hold game-changing business through wild vacillations, and allowing your investment thesis to play out over time, can be a daunting task.

While there are no shortage of viable reasons to sell -- e.g., tax purposes, management changes, or a personal emergency that requires capital -- the most-logical reason to part ways with a stock is when your original investment thesis no longer holds water.

The following three ultra-popular stocks have all delivered huge gains to their shareholders. However, the time has come for investors to book their profits and look for greener pastures.
