If you want to compound wealth in the stock market, you can do so by buying an index fund. But you can significantly boost your returns by picking above-average stocks. For example, the Mayne Pharma Group Limited (ASX:MYX) share price is up 93% in the last 1 year, clearly besting the market return of around 11% (not including dividends). So that should have shareholders smiling. In contrast, the longer term returns are negative, since the share price is 15% lower than it was three years ago.

So let's assess the underlying fundamentals over the last 1 year and see if they've moved in lock-step with shareholder returns.

Check out our latest analysis for Mayne Pharma Group

Mayne Pharma Group wasn't profitable in the last twelve months, it is unlikely we'll see a strong correlation between its share price and its earnings per share (EPS). Arguably revenue is our next best option. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. That's because fast revenue growth can be easily extrapolated to forecast profits, often of considerable size.

In the last year Mayne Pharma Group saw its revenue grow by 441%. That's a head and shoulders above most loss-making companies. The solid 93% share price gain goes down pretty well, but it's not necessarily as good as you might expect given the top notch revenue growth. If that's the case, now might be the time to take a close look at Mayne Pharma Group. Human beings have trouble conceptualizing (and valuing) exponential growth. Is that what we're seeing here?

A Different Perspective

It's good to see that Mayne Pharma Group has rewarded shareholders with a total shareholder return of 93% in the last twelve months. That certainly beats the loss of about 7% per year over the last half decade. This makes us a little wary, but the business might have turned around its fortunes. Investors who like to make money usually check up on insider purchases, such as the price paid, and total amount bought.
