When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But on the bright side, if you buy shares in a high quality company at the right price, you can gain well over 100%. For instance, the price of Sunzen Biotech Berhad (KLSE:SUNZEN) stock is up an impressive 237% over the last five years.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

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 five years of share price growth, Sunzen Biotech Berhad 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.
