If you buy and hold a stock for many years, you'd hope to be making a profit. Better yet, you'd like to see the share price move up more than the market average. Unfortunately for shareholders, while the Kratos Defense & Security Solutions, Inc. (NASDAQ:KTOS) share price is up 50% in the last five years, that's less than the market return. However, more recent buyers should be happy with the increase of 31% over the last year.

Since the stock has added US$153m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.
