Unfortunately for some shareholders, the China Ocean Fishing Holdings (HKG:8047) share price has dived 30% in the last thirty days. Given the 67% drop over the last year, some shareholders might be worried that they have become bagholders. What is a bagholder? It is a shareholder who has suffered a bad loss, but continues to hold indefinitely, without questioning their reasons for holding, even as the losses grow greater.

All else being equal, a share price drop should make a stock more attractive to potential investors. In the long term, share prices tend to follow earnings per share, but in the short term prices bounce around in response to short term factors (which are not always obvious). The implication here is that long term investors have an opportunity when expectations of a company are too low. One way to gauge market expectations of a stock is to look at its Price to Earnings Ratio (PE Ratio). A high P/E ratio means that investors have a high expectation about future growth, while a low P/E ratio means they have low expectations about future growth.

How Growth Rates Impact P/E Ratios

Generally speaking the rate of earnings growth has a profound impact on a company's P/E multiple. That's because companies that grow earnings per share quickly will rapidly increase the 'E' in the equation. And in that case, the P/E ratio itself will drop rather quickly. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.

China Ocean Fishing Holdings shrunk earnings per share by 36% over the last year.

Remember: P/E Ratios Don't Consider The Balance Sheet

The 'Price' in P/E reflects the market capitalization of the company. Thus, the metric does not reflect cash or debt held by the company. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

Such spending might be good or bad, overall, but the key point here is that you need to look at debt to understand the P/E ratio in context.

How Does China Ocean Fishing Holdings's Debt Impact Its P/E Ratio?

Net debt totals 17% of China Ocean Fishing Holdings's market cap. That's enough debt to impact the P/E ratio a little; so keep it in mind if you're comparing it to companies without debt.

The Verdict On China Ocean Fishing Holdings's P/E Ratio

China Ocean Fishing Holdings trades on a P/E ratio of 16.0, which is above its market average of 10.1. With modest debt but no EPS growth in the last year, it's fair to say the P/E implies some optimism about future earnings, from the market. Given China Ocean Fishing Holdings's P/E ratio has declined from 22.9 to 16.0 in the last month, we know for sure that the market is significantly less confident about the business today, than it was back then. For those who prefer to invest with the flow of momentum, that might be a bad sign, but for a contrarian, it may signal opportunity.

When the market is wrong about a stock, it gives savvy investors an opportunity. As value investor Benjamin Graham famously said, 'In the short run, the market is a voting machine but in the long run, it is a weighing machine.
