The last three months have been tough on Cars.com Inc. (NYSE:CARS) shareholders, who have seen the share price decline a rather worrying 34%. But that doesn't change the fact that shareholders have received really good returns over the last five years. In fact, the share price is 111% higher today. We think it's more important to dwell on the long term returns than the short term returns. Only time will tell if there is still too much optimism currently reflected in the 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.

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. 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 the last half decade, Cars.com became profitable. Sometimes, the start of profitability is a major inflection point that can signal fast earnings growth to come, which in turn justifies very strong share price gains. Since the company was unprofitable five years ago, but not three years ago, it's worth taking a look at the returns in the last three years, too. We can see that the Cars.com share price is up 8.3% in the last three years. During the same period, EPS grew by 69% each year. This EPS growth is higher than the 2.7% average annual increase in the share price over the same three years. So you might conclude the market is a little more cautious about the stock, these days.

A Different Perspective

Investors in Cars.com had a tough year, with a total loss of 31%, against a market gain of about 11%. 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 16% 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. 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.
