The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on the bright side, you can make far more than 100% on a really good stock. One great example is Moneysupermarket.com Group PLC (LON:MONY) which saw its share price drive 100% higher over five years. On top of that, the share price is up 20% in about a quarter. But this move may well have been assisted by the reasonably buoyant market (up 8.1% in 90 days).

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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.

Over half a decade, Moneysupermarket.com Group managed to grow its earnings per share at 20% a year. This EPS growth is higher than the 15% average annual increase in the share price. Therefore, it seems the market has become relatively pessimistic about the company.

You can see below how EPS has changed over time (discover the exact values by clicking on the image).

We consider it positive that insiders have made significant purchases in the last year. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Moneysupermarket.com Group, it has a TSR of 135% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

It's good to see that Moneysupermarket.com Group has rewarded shareholders with a total shareholder return of 25% in the last twelve months. And that does include the dividend. That gain is better than the annual TSR over five years, which is 19%. Therefore it seems like sentiment around the company has been positive lately. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time.
