The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But when you pick a company that is really flourishing, you can make more than 100%. For example, the NIOX Group Plc (LON:NIOX) share price has soared 241% in the last three years. How nice for those who held the stock! It's also good to see the share price up 28% over the last quarter.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

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.

NIOX Group became profitable within the last three years. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here.

It is of course excellent to see how NIOX Group has grown profits over the years, but the future is more important for shareholders. This free interactive report on NIOX Group's balance sheet strength is a great place to start, if you want to investigate the stock further.

A Different Perspective

It's nice to see that NIOX Group shareholders have received a total shareholder return of 17% over the last year. Notably the five-year annualised TSR loss of 8% per year compares very unfavourably with the recent share price performance. The long term loss makes us cautious, but the short term TSR gain certainly hints at a brighter future. 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. To that end, you should learn about the 2 warning signs we've spotted with NIOX Group (including 1 which is concerning) .
