Generally speaking long term investing is the way to go. But no-one is immune from buying too high. For example, after five long years the RongFa Nuclear Equipment Co., Ltd. (SZSE:002366) share price is a whole 60% lower. We certainly feel for shareholders who bought near the top. And it's not just long term holders hurting, because the stock is down 41% in the last year. Furthermore, it's down 19% in about a quarter. That's not much fun for holders.

After losing 6.4% this past week, it's worth investigating the company's fundamentals to see what we can infer from past performance.

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...' One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

RongFa Nuclear Equipment became profitable within the last five years. Most would consider that to be a good thing, so it's counter-intuitive to see the share price declining. Other metrics might give us a better handle on how its value is changing over time.

The revenue decline of 1.7% isn't too bad. But it's quite possible the market had expected better; a closer look at the revenue trends might explain the pessimism.

A Different Perspective

While the broader market lost about 13% in the twelve months, RongFa Nuclear Equipment shareholders did even worse, losing 41%. Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 10% per year over five years. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. It's always interesting to track share price performance over the longer term. But to understand RongFa Nuclear Equipment better, we need to consider many other factors. Consider for instance, the ever-present spectre of investment risk. We've identified 2 warning signs with RongFa Nuclear Equipment (at least 1 which makes us a bit uncomfortable) , and understanding them should be part of your investment process.
