Investing in Atec (KOSDAQ:045660) five years ago would have delivered you a 81% gain

Generally speaking the aim of active stock picking is to find companies that provide returns that are superior to the market average. And the truth is, you can make significant gains if you buy good quality businesses at the right price. For example, the Atec Co. Ltd. (KOSDAQ:045660) share price is up 70% in the last 5 years, clearly besting the market return of around 29% (ignoring dividends). However, more recent returns haven't been as impressive as that, with the stock returning just 43% in the last year, including dividends.

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

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.

Atec's earnings per share are down 0.8% per year, despite strong share price performance over five years.

So it's hard to argue that the earnings per share are the best metric to judge the company, as it may not be optimized for profits at this point. Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

The modest 1.3% dividend yield is unlikely to be propping up the share price. The revenue reduction of per year is not a positive. It certainly surprises us that the share price is up, but perhaps a closer examination of the data will yield answers.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Atec, it has a TSR of 81% for the last 5 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's good to see that Atec has rewarded shareholders with a total shareholder return of 43% in the last twelve months. And that does include the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 13% per year), it would seem that the stock's performance has improved in recent times. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
