Ideally, your overall portfolio should beat the market average. But the main game is to find enough winners to more than offset the losers So we wouldn't blame long term Zhongyu Energy Holdings Limited (HKG:3633) shareholders for doubting their decision to hold, with the stock down 41% over a half decade.

After losing 3.4% 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. 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 five years over which the share price declined, Zhongyu Energy Holdings' earnings per share (EPS) dropped by 20% each year. The share price decline of 10% per year isn't as bad as the EPS decline. So the market may previously have expected a drop, or else it expects the situation will improve. The high P/E ratio of 49.90 suggests that shareholders believe earnings will grow in the years ahead.

What About The Total Shareholder Return (TSR)?

Investors should note that there's a difference between Zhongyu Energy Holdings' total shareholder return (TSR) and its share price change, which we've covered above. Arguably the TSR is a more complete return calculation because it accounts for the value of dividends (as if they were reinvested), along with the hypothetical value of any discounted capital that have been offered to shareholders. Dividends have been really beneficial for Zhongyu Energy Holdings shareholders, and that cash payout explains why its total shareholder loss of 38%, over the last 5 years, isn't as bad as the share price return.

A Different Perspective

Zhongyu Energy Holdings shareholders are down 19% for the year, but the market itself is up 3.5%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 7% per year over five years. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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.
