In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But the main game is to find enough winners to more than offset the losers So we wouldn't blame long term China High-Speed Railway Technology Co., Ltd. (SZSE:000008) shareholders for doubting their decision to hold, with the stock down 41% over a half decade. But it's up 7.1% in the last week.

While the last five years has been tough for China High-Speed Railway Technology 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.

Given that China High-Speed Railway Technology didn't make a profit in the last twelve months, we'll focus on revenue growth to form a quick view of its business development. Shareholders of unprofitable companies usually desire strong revenue growth. That's because it's hard to be confident a company will be sustainable if revenue growth is negligible, and it never makes a profit.

In the last five years China High-Speed Railway Technology saw its revenue shrink by 6.5% per year. That's not what investors generally want to see. The stock hasn't done well for shareholders in the last five years, falling 7%, annualized. Unfortunately, though, it makes sense given the lack of either profits or revenue growth. Without profits, its hard to see how shareholders win if the revenue keeps falling.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

A Different Perspective

Although it hurts that China High-Speed Railway Technology returned a loss of 15% in the last twelve months, the broader market was actually worse, returning a loss of 20%. Given the total loss of 7% per year over five years, it seems returns have deteriorated in the last twelve months. While some investors do well specializing in buying companies that are struggling (but nonetheless undervalued), don't forget that Buffett said that 'turnarounds seldom turn'. 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.
