While it may not be enough for some shareholders, we think it is good to see the Nanjing Xinlian Electronics Co., Ltd (SZSE:002546) share price up 29% in a single quarter. But that is minimal compensation for the share price under-performance over the last year. After all, the share price is down 14% in the last year, significantly under-performing the market.

While the last year has been tough for Nanjing Xinlian Electronics shareholders, this past week has shown signs of promise. So let's look at the longer term fundamentals and see if they've been the driver of the negative returns.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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.

During the last year Nanjing Xinlian Electronics grew its earnings per share, moving from a loss to a profit.

When a company has just transitioned to profitability, earnings per share growth is not always the best way to look at the share price action. But we may find different metrics more enlightening.

Nanjing Xinlian Electronics managed to grow revenue over the last year, which is usually a real positive. Since the fundamental metrics don't readily explain the share price drop, there might be an opportunity if the market has overreacted.

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. 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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, Nanjing Xinlian Electronics' TSR for the last 1 year was -12%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

While the broader market gained around 6.5% in the last year, Nanjing Xinlian Electronics shareholders lost 12% (even including dividends). Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. On the bright side, long term shareholders have made money, with a gain of 4% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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.
