Investors push Proteomics International Laboratories (ASX:PIQ) 12% lower this week, company's increasing losses might be to blame

The Proteomics International Laboratories Limited (ASX:PIQ) share price has had a bad week, falling 12%. But in stark contrast, the returns over the last half decade have impressed. Indeed, the share price is up an impressive 296% in that time. We think it's more important to dwell on the long term returns than the short term returns. The more important question is whether the stock is too cheap or too expensive today.

While the stock has fallen 12% this week, it's worth focusing on the longer term and seeing if the stocks historical returns have been driven by the underlying fundamentals.

Check out our latest analysis for Proteomics International Laboratories

Proteomics International Laboratories isn't currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. 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.

For the last half decade, Proteomics International Laboratories can boast revenue growth at a rate of 5.7% per year. That's not a very high growth rate considering the bottom line. So we wouldn't have expected to see the share price to have lifted 32% for each year during that time, but that's what happened. Shareholders should be pretty happy with that, although interested investors might want to examine the financial data more closely to see if the gains are really justified. Some might suggest that the sentiment around the stock is rather positive.
