Antofagasta plc (LON:ANTO) shareholders might be concerned after seeing the share price drop 16% in the last quarter. But don't let that distract from the very nice return generated over three years. In the last three years the share price is up, 90%: better than the market.

Since the long term performance has been good but there's been a recent pullback of 3.7%, let's check if the fundamentals match the share price.

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 three years of share price growth, Antofagasta achieved compound earnings per share growth of 45% per year. The average annual share price increase of 24% is actually lower than the EPS growth. So it seems investors have become more cautious about the company, over time. This cautious sentiment is reflected in its (fairly low) P/E ratio of 11.80.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Antofagasta, it has a TSR of 116% for the last 3 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

Investors in Antofagasta had a tough year, with a total loss of 2.7% (including dividends), against a market gain of about 2.8%. 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 12%, 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. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too. Even so, be aware that Antofagasta is showing 3 warning signs in our investment analysis , and 1 of those makes us a bit uncomfortable...
