If you love investing in stocks you're bound to buy some losers. But long term Guangdong Faith Long Crystal Technology Co.,LTD. (SZSE:300460) shareholders have had a particularly rough ride in the last three year. Sadly for them, the share price is down 57% in that time. And the ride hasn't got any smoother in recent times over the last year, with the price 22% lower in that time. Shareholders have had an even rougher run lately, with the share price down 17% in the last 90 days.

Given the past week has been tough on shareholders, let's investigate the fundamentals and see what we can learn.

Because Guangdong Faith Long Crystal TechnologyLTD made a loss in the last twelve months, we think the market is probably more focussed on revenue and revenue growth, at least for now. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. That's because fast revenue growth can be easily extrapolated to forecast profits, often of considerable size.

Over the last three years, Guangdong Faith Long Crystal TechnologyLTD's revenue dropped 18% per year. That's definitely a weaker result than most pre-profit companies report. Arguably, the market has responded appropriately to this business performance by sending the share price down 16% (annualized) in the same time period. Bagholders or 'baggies' are people who buy more of a stock as the price collapses. They are then left 'holding the bag' if the shares turn out to be worthless. After losing money on a declining business with falling stock price, we always consider whether eager bagholders are still offering us a reasonable exit price.

A Different Perspective

We regret to report that Guangdong Faith Long Crystal TechnologyLTD shareholders are down 22% for the year. Unfortunately, that's worse than the broader market decline of 12%. 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. Longer term investors wouldn't be so upset, since they would have made 3%, each year, over five years. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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.
