The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But when you pick a company that is really flourishing, you can make more than 100%. For instance, the price of Flex Ltd. (NASDAQ:FLEX) stock is up an impressive 198% over the last five years. On top of that, the share price is up 23% in about a quarter.

So let's assess the underlying fundamentals over the last 5 years and see if they've moved in lock-step with shareholder returns.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During the five years of share price growth, Flex moved from a loss to profitability. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here. Given that the company made a profit three years ago, but not five years ago, it is worth looking at the share price returns over the last three years, too. We can see that the Flex share price is up 124% in the last three years. During the same period, EPS grew by 2.6% each year. Notably, the EPS growth has been slower than the annualised share price gain of 31% over three years. So one can reasonably conclude the market is more enthusiastic about the stock than it was three years ago.

The image below shows how EPS has tracked over time (if you click on the image you can see greater detail).

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Flex, it has a TSR of 310% for the last 5 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's nice to see that Flex shareholders have received a total shareholder return of 82% over the last year. And that does include the dividend. That's better than the annualised return of 33% over half a decade, implying that the company is doing better recently. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
