ATS (TSE:ATS) sheds 7.5% this week, as yearly returns fall more in line with earnings growth

It might be of some concern to shareholders to see the ATS Corporation (TSE:ATS) share price down 13% in the last month. On the bright side the returns have been quite good over the last half decade. Its return of 81% has certainly bested the market return! While the long term returns are impressive, we do have some sympathy for those who bought more recently, given the 31% drop, in the last year.

Although ATS has shed CA$308m from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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 five years of share price growth, ATS achieved compound earnings per share (EPS) growth of 9.2% per year. This EPS growth is slower than the share price growth of 13% 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.

A Different Perspective

While the broader market gained around 19% in the last year, ATS shareholders lost 31%. 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. Longer term investors wouldn't be so upset, since they would have made 13%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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.
