While Taseko Mines Limited (TSE:TKO) shareholders are probably generally happy, the stock hasn't had particularly good run recently, with the share price falling 19% in the last quarter. But over five years returns have been remarkably great. Indeed, the share price is up a whopping 391% in that time. So it might be that some shareholders are taking profits after good performance. Only time will tell if there is still too much optimism currently reflected in the share price.

While the stock has fallen 12% this week, it's worth focusing on the longer term and seeing if the stocks historical returns have been driven by the underlying fundamentals.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During the five years of share price growth, Taseko Mines moved from a loss to profitability. 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. Given that the company made a profit three years ago, but not five years ago, it is worth looking at the share price returns over the last three years, too. We can see that the Taseko Mines share price is up 12% in the last three years. During the same period, EPS grew by 69% each year. This EPS growth is higher than the 4% average annual increase in the share price over the same three years. Therefore, it seems the market has moderated its expectations for growth, somewhat.
