Volatility 101: Should Pharmaxis (ASX:PXS) Shares Have Dropped 46%?

In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But in any portfolio, there are likely to be some stocks that fall short of that benchmark. Unfortunately, that's been the case for longer term Pharmaxis Ltd (ASX:PXS) shareholders, since the share price is down 46% in the last three years, falling well short of the market return of around 36%. The more recent news is of little comfort, with the share price down 46% in a year. The last week also saw the share price slip down another 44%.

Given that Pharmaxis 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. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. Some companies are willing to postpone profitability to grow revenue faster, but in that case one does expect good top-line growth.

In the last three years, Pharmaxis saw its revenue grow by 7.0% per year, compound. Given it's losing money in pursuit of growth, we are not really impressed with that. The stock dropped 19% during that time. If revenue growth accelerates, we might see the share price bounce. But ultimately the key will be whether the company can become profitability.

A Different Perspective

Pharmaxis shareholders are down 46% for the year, but the market itself is up 28%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 1.3% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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.
