Unfortunately for some shareholders, the Chi Ho Development Holdings (HKG:8423) share price has dived 37% in the last thirty days. Given the 75% 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). So, on certain occasions, long term focussed investors try to take advantage of pessimistic expectations to buy shares at a better price. 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.

The market is optimistic about the future, but that doesn't guarantee future growth. So further research is always essential. I often monitor director buying and selling.

How Growth Rates Impact P/E Ratios

When earnings fall, the 'E' decreases, over time. Therefore, even if you pay a low multiple of earnings now, that multiple will become higher in the future. A higher P/E should indicate the stock is expensive relative to others -- and that may encourage shareholders to sell.

Chi Ho Development Holdings saw earnings per share decrease by 19% last year. And it has shrunk its earnings per share by 2.8% per year over the last three years. This growth rate might warrant a low P/E ratio.

A Limitation: P/E Ratios Ignore Debt and Cash In The Bank

It's important to note that the P/E ratio considers the market capitalization, not the enterprise value. Thus, the metric does not reflect cash or debt held by the company. The exact same company would hypothetically deserve a higher P/E ratio if it had a strong balance sheet, than if it had a weak one with lots of debt, because a cashed up company can spend on growth.

Spending on growth might be good or bad a few years later, but the point is that the P/E ratio does not account for the option (or lack thereof).

So What Does Chi Ho Development Holdings's Balance Sheet Tell Us?

Chi Ho Development Holdings's net debt is 4.8% of its market cap. The market might award it a higher P/E ratio if it had net cash, but its unlikely this low level of net borrowing is having a big impact on the P/E multiple.
