We think all investors should try to buy and hold high quality multi-year winners. While not every stock performs well, when investors win, they can win big. For example, the Monolithic Power Systems, Inc. (NASDAQ:MPWR) share price is up a whopping 372% in the last half decade, a handsome return for long term holders. And this is just one example of the epic gains achieved by some long term investors. Also pleasing for shareholders was the 40% gain in the last three months. But this move may well have been assisted by the reasonably buoyant market (up 18% in 90 days).

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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).

Over half a decade, Monolithic Power Systems managed to grow its earnings per share at 34% a year. So the EPS growth rate is rather close to the annualized share price gain of 36% per year. This indicates that investor sentiment towards the company has not changed a great deal. Indeed, it would appear the share price is reacting to the EPS.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Monolithic Power Systems the TSR over the last 5 years was 391%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's good to see that Monolithic Power Systems has rewarded shareholders with a total shareholder return of 53% in the last twelve months. Of course, that includes the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 37% per year), it would seem that the stock's performance has improved in recent times. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
