Stock pickers are generally looking for stocks that will outperform the broader market. And while active stock picking involves risks (and requires diversification) it can also provide excess returns. To wit, the Data#3 share price has climbed 91% in five years, easily topping the market return of 24% (ignoring dividends). On the other hand, the more recent gains haven't been so impressive, with shareholders gaining just 8.3%, including dividends.

Since the stock has added AU$116m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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, Data#3 managed to grow its earnings per share at 16% a year. This EPS growth is reasonably close to the 14% average annual increase in the share price. 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.

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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Data#3 the TSR over the last 5 years was 122%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

Data#3 provided a TSR of 8.3% over the last twelve months. Unfortunately this falls short of the market return. If we look back over five years, the returns are even better, coming in at 17% per year for five years. 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. Consider for instance, the ever-present spectre of investment risk. We've identified 1 warning sign with Data#3 , and understanding them should be part of your investment process.
