Passive investing in index funds can generate returns that roughly match the overall market. But in our experience, buying the right stocks can give your wealth a significant boost. For example, the Teledyne Technologies Incorporated (NYSE:TDY) share price is 85% higher than it was five years ago, which is more than the market average. Zooming in, the stock is actually down 1.2% in the last year.

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, Teledyne Technologies managed to grow its earnings per share at 15% a year. This EPS growth is reasonably close to the 13% average annual increase in the share price. That suggests that the market sentiment around the company hasn't changed much over that time. Rather, the share price has approximately tracked EPS growth.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years.

A Different Perspective

Investors in Teledyne Technologies had a tough year, with a total loss of 1.2%, against a market gain of about 22%. 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 13% 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. If you would like to research Teledyne Technologies in more detail then you might want to take a look at whether insiders have been buying or selling shares in the company.
