While shareholders of Microbix Biosystems (TSE:MBX) are in the black over 3 years, those who bought a week ago aren't so fortunate

While Microbix Biosystems Inc. (TSE:MBX) shareholders are probably generally happy, the stock hasn't had particularly good run recently, with the share price falling 25% in the last quarter. But that doesn't undermine the rather lovely longer-term return, if you measure over the last three years. In three years the stock price has launched 112% higher: a great result. It's not uncommon to see a share price retrace a bit, after a big gain. Only time will tell if there is still too much optimism currently reflected in the share price.

Although Microbix Biosystems has shed CA$8.3m from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.
