While shareholders of Richardson Electronics (NASDAQ:RELL) are in the black over 3 years, those who bought a week ago aren't so fortunate

It's been a soft week for Richardson Electronics, Ltd. (NASDAQ:RELL) shares, which are down 15%. But over the last three years the stock has shone bright like a diamond. The longer term view reveals that the share price is up 350% in that period. Arguably, the recent fall is to be expected after such a strong rise. The share price action could signify that the business itself is dramatically improved, in that time.

Although Richardson Electronics has shed US$44m from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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 three years of share price growth, Richardson Electronics moved from a loss to profitability. Given the importance of this milestone, it's not overly surprising that the share price has increased strongly.

We know that Richardson Electronics has improved its bottom line over the last three years, but what does the future have in store? It might be well worthwhile taking a look at our free report on how its financial position has changed over time.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Richardson Electronics, it has a TSR of 393% for the last 3 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 good to see that Richardson Electronics has rewarded shareholders with a total shareholder return of 57% in the last twelve months. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 21% 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. Consider for instance, the ever-present spectre of investment risk.
