Investing in TMX Group (TSE:X) five years ago would have delivered you a 125% gain

When we invest, we're generally looking for stocks that outperform the market average. And while active stock picking involves risks (and requires diversification) it can also provide excess returns. To wit, the TMX Group share price has climbed 98% in five years, easily topping the market return of 35% (ignoring dividends). However, more recent returns haven't been as impressive as that, with the stock returning just 6.3% in the last year , 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.

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).

Over half a decade, TMX Group managed to grow its earnings per share at 13% a year. So the EPS growth rate is rather close to the annualized share price gain of 15% per year. That suggests that the market sentiment around the company hasn't changed much over that time. Indeed, it would appear the share price is reacting to the EPS.

We like that insiders have been buying shares in the last twelve months. Even so, future earnings will be far more important to whether current shareholders make money.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, TMX Group's TSR for the last 5 years was 125%, which exceeds the share price return mentioned earlier. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

TMX Group shareholders are up 6.3% for the year (even including dividends). But that return falls short of the market. On the bright side, the longer term returns (running at about 18% a year, over half a decade) look better. It may well be that this is a business worth popping on the watching, given the continuing positive reception, over time, from the market. 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.
