Anhui Zhonghuan Environmental Protection TechnologyLtd (SZSE:300692) shareholders have lost 41% over 1 year, earnings decline likely the culprit

Passive investing in an index fund is a good way to ensure your own returns roughly match the overall market. Active investors aim to buy stocks that vastly outperform the market - but in the process, they risk under-performance. That downside risk was realized by Anhui Zhonghuan Environmental Protection Technology Co.,Ltd (SZSE:300692) shareholders over the last year, as the share price declined 41%. That's disappointing when you consider the market declined 10%. We note that it has not been easy for shareholders over three years, either; the share price is down 41% in that time. More recently, the share price has dropped a further 17% in a month.

After losing 13% this past week, it's worth investigating the company's fundamentals to see what we can infer from past performance.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Unfortunately Anhui Zhonghuan Environmental Protection TechnologyLtd reported an EPS drop of 44% for the last year. This proportional reduction in earnings per share isn't far from the 41% decrease in the share price. Given the lower EPS we might have expected investors to lose confidence in the stock, but that doesn't seemed to have happened. Instead, the change in the share price seems to reduction in earnings per share, alone.

A Different Perspective

We regret to report that Anhui Zhonghuan Environmental Protection TechnologyLtd shareholders are down 41% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 10%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 6% 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. 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. Take risks, for example - Anhui Zhonghuan Environmental Protection TechnologyLtd has 2 warning signs (and 1 which is concerning) we think you should know about.
