Investors in Ambu (CPH:AMBU B) have seen respectable returns of 80% over the past year

Passive investing in index funds can generate returns that roughly match the overall market. But you can significantly boost your returns by picking above-average stocks. To wit, the Ambu A/S (CPH:AMBU B) share price is 80% higher than it was a year ago, much better than the market return of around 20% (not including dividends) in the same period. That's a solid performance by our standards! Unfortunately the longer term returns are not so good, with the stock falling 23% in the last three years.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.
