The main aim of stock picking is to find the market-beating stocks. But every investor is virtually certain to have both over-performing and under-performing stocks. At this point some shareholders may be questioning their investment in Nanjing Securities Co., Ltd. (SHSE:601990), since the last five years saw the share price fall 30%.

Since shareholders are down over the longer term, lets look at the underlying fundamentals over the that time and see if they've been consistent with returns.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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.

During the unfortunate half decade during which the share price slipped, Nanjing Securities actually saw its earnings per share (EPS) improve by 12% per year. So it doesn't seem like EPS is a great guide to understanding how the market is valuing the stock. Or possibly, the market was previously very optimistic, so the stock has disappointed, despite improving EPS.

Due to the lack of correlation between the EPS growth and the falling share price, it's worth taking a look at other metrics to try to understand the share price movement.

We don't think that the 1.3% is big factor in the share price, since it's quite small, as dividends go. In contrast to the share price, revenue has actually increased by 7.6% a year in the five year period. A more detailed examination of the revenue and earnings may or may not explain why the share price languishes; there could be an opportunity.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Nanjing Securities, it has a TSR of -26% 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

While it's certainly disappointing to see that Nanjing Securities shares lost 11% throughout the year, that wasn't as bad as the market loss of 16%. Unfortunately, last year's performance may indicate unresolved challenges, given that it's worse than the annualised loss of 5% over the last half decade. Whilst Baron Rothschild does tell the investor "buy when there's blood in the streets, even if the blood is your own", buyers would need to examine the data carefully to be comfortable that the business itself is sound. 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. Consider for instance, the ever-present spectre of investment risk. We've identified 2 warning signs with Nanjing Securities (at least 1 which makes us a bit uncomfortable) , and understanding them should be part of your investment process.
