When you buy a stock there is always a possibility that it could drop 100%. But on the bright side, you can make far more than 100% on a really good stock. For instance, the price of Flex Ltd. (NASDAQ:FLEX) stock is up an impressive 226% over the last five years. Also pleasing for shareholders was the 29% gain in the last three months. But this could be related to the strong market, which is up 12% in the last three months.

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving fundamentals.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During the last half decade, Flex became profitable. Sometimes, the start of profitability is a major inflection point that can signal fast earnings growth to come, which in turn justifies very strong share price gains. Since the company was unprofitable five years ago, but not three years ago, it's worth taking a look at the returns in the last three years, too. We can see that the Flex share price is up 106% in the last three years. During the same period, EPS grew by 2.6% each year. This EPS growth is lower than the 27% average annual increase in the share price over three years. So one can reasonably conclude the market is more enthusiastic about the stock than it was three years ago.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Flex, it has a TSR of 348% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

It's good to see that Flex has rewarded shareholders with a total shareholder return of 106% in the last twelve months. That's including the dividend. That's better than the annualised return of 35% over half a decade, implying that the company is doing better recently. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. It's always interesting to track share price performance over the longer term. But to understand Flex better, we need to consider many other factors. Consider for instance, the ever-present spectre of investment risk. We've identified 2 warning signs with Flex , and understanding them should be part of your investment process.
