It is a pleasure to report that the Quanterix Corporation (NASDAQ:QTRX) is up 63% in the last quarter. But spare a thought for the long term holders, who have held the stock as it bled value over the last five years. Like a ship taking on water, the share price has sunk 83% in that time. It's true that the recent bounce could signal the company is turning over a new leaf, but we are not so sure. The real question is whether the business can leave its past behind and improve itself over the years ahead. 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.

On a more encouraging note the company has added US$71m to its market cap in just the last 7 days, so let's see if we can determine what's driven the five-year loss for shareholders.

Given that Quanterix 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 hope to see good 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 half decade, Quanterix saw its revenue increase by 8.0% per year. That's a fairly respectable growth rate. So it is unexpected to see the stock down 13% per year in the last five years. The truth is that the growth might be below expectations, and investors are probably worried about the continual losses.

We consider it positive that insiders have made significant purchases in the last year. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business. So it makes a lot of sense to check out what analysts think Quanterix will earn in the future (free profit forecasts).

A Different Perspective

Quanterix shareholders are down 41% for the year, but the market itself is up 14%. 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 13% 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.
