Five9, Inc. (NASDAQ:FIVN) shareholders should be happy to see the share price up 11% in the last month. But that is meagre solace in the face of the shocking decline over three years. The share price has sunk like a leaky ship, down 81% in that time. So we're relieved for long term holders to see a bit of uplift. Only time will tell if the company can sustain the turnaround. We really feel for shareholders in this scenario. It's a good reminder of the importance of diversification, and it's worth keeping in mind there's more to life than money, anyway.

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

Five9 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. Shareholders of unprofitable companies usually desire strong revenue growth. That's because it's hard to be confident a company will be sustainable if revenue growth is negligible, and it never makes a profit.

In the last three years, Five9 saw its revenue grow by 20% per year, compound. That's a fairly respectable growth rate. So it's hard to believe the share price decline of 22% per year is due to the revenue. It could be that the losses were much larger than expected. If you buy into companies that lose money then you always risk losing money yourself. Just don't lose the lesson.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

A Different Perspective

Investors in Five9 had a tough year, with a total loss of 47%, against a market gain of about 40%. 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. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 8% over the last half decade. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. 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.
