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 Lam Research Corporation (NASDAQ:LRCX) stock is up an impressive 286% over the last five years. In contrast, the stock has fallen 9.6% in the last 30 days. We note that the broader market is down 10% in the last month, and this may have impacted Lam Research's share price.

Let's take a look at the underlying fundamentals over the longer term, and see if they've been consistent with shareholders returns.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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, Lam Research managed to grow its earnings per share at 19% a year. This EPS growth is slower than the share price growth of 31% per year, over the same period. So it's fair to assume the market has a higher opinion of the business than it did five years ago. That's not necessarily surprising considering the five-year track record of earnings growth.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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 Lam Research the TSR over the last 5 years was 312%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Lam Research shareholders are down 18% for the year (even including dividends), but the market itself is up 8.2%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. On the bright side, long term shareholders have made money, with a gain of 33% per year over half a decade. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend.
