Generally speaking the aim of active stock picking is to find companies that provide returns that are superior to the market average. And while active stock picking involves risks (and requires diversification) it can also provide excess returns. For example, long term Bioventix PLC (LON:BVXP) shareholders have enjoyed a 42% share price rise over the last half decade, well in excess of the market decline of around 7.5% (not including dividends). On the other hand, the more recent gains haven't been so impressive, with shareholders gaining just 9.1% , including dividends .

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Over half a decade, Bioventix managed to grow its earnings per share at 8.9% a year. This EPS growth is higher than the 7% average annual increase in the share price. So it seems the market isn't so enthusiastic about the stock these days.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward. Before buying or selling a stock, we always recommend a close examination of historic growth trends, available here..

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, Bioventix's TSR for the last 5 years was 73%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!



A Different Perspective

We're pleased to report that Bioventix shareholders have received a total shareholder return of 9.1% over one year. Of course, that includes the dividend. However, the TSR over five years, coming in at 12% per year, is even more impressive. 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. To that end, you should be aware of the  1 warning sign  we've spotted with Bioventix .
