For many investors, the main point of stock picking is to generate higher returns than the overall market. But the risk of stock picking is that you will likely buy under-performing companies. We regret to report that long term Evertz Technologies Limited (TSE:ET) shareholders have had that experience, with the share price dropping 16% in three years, versus a market return of about 27%. It's down 3.1% in the last seven days.

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...' By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

Evertz Technologies saw its EPS decline at a compound rate of 10% per year, over the last three years. In comparison the 6% compound annual share price decline isn't as bad as the EPS drop-off. So the market may not be too worried about the EPS figure, at the moment -- or it may have previously priced some of the drop in.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Evertz Technologies, it has a TSR of 1.0% for the last 3 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

Evertz Technologies shareholders gained a total return of 2.2% during the year. But that was short of the market average. On the bright side, the longer term returns (running at about 4% a year, over half a decade) look better. It's quite possible the business continues to execute with prowess, even as the share price gains are slowing. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
