If you buy and hold a stock for many years, you'd hope to be making a profit. Better yet, you'd like to see the share price move up more than the market average. Unfortunately for shareholders, while the Harmonic Inc. (NASDAQ:HLIT) share price is up 73% in the last five years, that's less than the market return. Over the last twelve months the stock price has risen a very respectable 8.2%.

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.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During the last half decade, Harmonic became profitable. That's generally thought to be a genuine positive, so investors may expect to see an increasing share price. 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 Harmonic share price is up 21% in the last three years. Meanwhile, EPS is up 120% per year. This EPS growth is higher than the 7% average annual increase in the share price over the same three years. Therefore, it seems the market has moderated its expectations for growth, somewhat.

A Different Perspective

Harmonic shareholders gained a total return of 8.2% during the year. Unfortunately this falls short of the market return. If we look back over five years, the returns are even better, coming in at 12% per year for five years. It may well be that this is a business worth popping on the watching, given the continuing positive reception, over time, from the market. 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.
