We think that it's fair to say that the possibility of finding fantastic multi-year winners is what motivates many investors. Mistakes are inevitable, but a single top stock pick can cover any losses, and so much more. One such superstar is Griffin Mining Limited (LON:GFM), which saw its share price soar 367% in three years. Also pleasing for shareholders was the 17% gain in the last three months.

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. 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 three years of share price growth, Griffin Mining moved from a loss to profitability. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here.

AIM:GFM Past and Future Earnings, April 11th 2019

We like that insiders have been buying shares in the last twelve months. Even so, future earnings will be far more important to whether current shareholders make money. Before buying or selling a stock, we always recommend a close examination of historic growth trends, available here..

A Different Perspective

While the broader market gained around 6.4% in the last year, Griffin Mining shareholders lost 16%. 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 29% 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.
