It might seem bad, but the worst that can happen when you buy a stock (without leverage) is that its share price goes to zero. But when you pick a company that is really flourishing, you can make more than 100%. For example, the TBC Bank Group PLC (LON:TBCG) share price has soared 125% in the last three years. That sort of return is as solid as granite. We note the stock price is up 1.6% in the last seven days.

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

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

TBC Bank Group was able to grow its EPS at 41% per year over three years, sending the share price higher. The average annual share price increase of 31% is actually lower than the EPS growth. So it seems investors have become more cautious about the company, over time. We'd venture the lowish P/E ratio of 4.94 also reflects the negative sentiment around the stock.

It's good to see that there was some significant insider buying in the last three months. That's a positive. That said, we think earnings and revenue growth trends are even more important factors to consider.

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, TBC Bank Group's TSR for the last 3 years was 169%, 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

It's nice to see that TBC Bank Group shareholders have received a total shareholder return of 25% over the last year. And that does include the dividend. That's better than the annualised return of 20% over half a decade, implying that the company is doing better recently. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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.
