PolyNovo Limited (ASX:PNV) shareholders might be concerned after seeing the share price drop 24% in the last quarter. But in stark contrast, the returns over the last half decade have impressed. In fact, the share price is 181% higher today. Generally speaking the long term returns will give you a better idea of business quality than short periods can. Of course, that doesn't necessarily mean it's cheap now. Unfortunately not all shareholders will have held it for five years, so spare a thought for those caught in the 41% decline over the last three years: that's a long time to wait for profits.

Although PolyNovo has shed AU$86m from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

Given that PolyNovo didn't make a profit in the last twelve months, we'll focus on revenue growth to form a quick view of its business development. When a company doesn't make profits, we'd generally expect to see good revenue growth. That's because fast revenue growth can be easily extrapolated to forecast profits, often of considerable size.

For the last half decade, PolyNovo can boast revenue growth at a rate of 38% per year. That's well above most pre-profit companies. So it's not entirely surprising that the share price reflected this performance by increasing at a rate of 23% per year, in that time. This suggests the market has well and truly recognized the progress the business has made. PolyNovo seems like a high growth stock - so growth investors might want to add it to their watchlist.

A Different Perspective

It's nice to see that PolyNovo shareholders have received a total shareholder return of 20% over the last year. Having said that, the five-year TSR of 23% a year, is even better. It's always interesting to track share price performance over the longer term. But to understand PolyNovo better, we need to consider many other factors.
