The past three years for Bio-Techne (NASDAQ:TECH) investors has not been profitable

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 Bio-Techne Corporation (NASDAQ:TECH) shareholders, since the share price is down 39% in the last three years, falling well short of the market return of around 64%. The more recent news is of little comfort, with the share price down 33% in a year. The falls have accelerated recently, with the share price down 17% in the last three months.

It's worthwhile assessing if the company's economics have been moving in lockstep with these underwhelming shareholder returns, or if there is some disparity between the two. So let's do just that.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During the three years that the share price fell, Bio-Techne's earnings per share (EPS) dropped by 16% each year. This fall in EPS isn't far from the rate of share price decline, which was 15% per year. So it seems that investor expectations of the company are staying pretty steady, despite the disappointment. It seems like the share price is reflecting the declining earnings per share.

A Different Perspective

While the broader market gained around 11% in the last year, Bio-Techne shareholders lost 32% (even including dividends). Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 4% per year over five years. 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. It's always interesting to track share price performance over the longer term. But to understand Bio-Techne better, we need to consider many other factors.
