The simplest way to invest in stocks is to buy exchange traded funds. But the truth is, you can make significant gains if you buy good quality businesses at the right price. For example, the Plexus Corp. (NASDAQ:PLXS) share price is 73% higher than it was five years ago, which is more than the market average. In stark contrast, the stock price has actually fallen 3.0% in the last year.

On the back of a solid 7-day performance, let's check what role the company's fundamentals have played in driving long term shareholder 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. 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 five years of share price growth, Plexus achieved compound earnings per share (EPS) growth of 2.2% per year. This EPS growth is lower than the 12% average annual increase in the share price. This suggests that market participants hold the company in higher regard, these days. And that's hardly shocking given the track record of growth.

A Different Perspective

Plexus shareholders are down 3.0% for the year, but the market itself is up 18%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Longer term investors wouldn't be so upset, since they would have made 12%, each year, over five years. 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.
