Nobody is perfect. That means every stock picker makes mistakes, and at some point, you will lose money on an investment. But if you do your research and build a portfolio of high-quality companies, you’ll likely have some big winners, too — monster stocks that grow to multiple times their current value.
Those big winners can help ease the pain of the losses from other stocks you might hold, because a stock can only lose 100% of its value, but there is no limit on the upside.
