In Construction Holdings (HKG:1500) shares have had a really impressive month, gaining 31%, after some slippage. But shareholders may not all be feeling jubilant, since the share price is still down 25% in the last year.

All else being equal, a sharp share price increase should make a stock less 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 deep value investors might steer clear when expectations of a company are too high. 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

Companies that shrink earnings per share quickly will rapidly decrease the 'E' in the equation. That means unless the share price falls, the P/E will increase in a few years. A higher P/E should indicate the stock is expensive relative to others -- and that may encourage shareholders to sell.

In Construction Holdings saw earnings per share decrease by 54% last year. And over the longer term (5 years) earnings per share have decreased 33% annually. This might lead to muted expectations.

Don't Forget: The P/E Does Not Account For Debt or Bank Deposits

The 'Price' in P/E reflects the market capitalization of the company. So it won't reflect the advantage of cash, or disadvantage of debt. Theoretically, a business can improve its earnings (and produce a lower P/E in the future) by investing in growth. That means taking on debt (or spending its cash).

Such expenditure might be good or bad, in the long term, but the point here is that the balance sheet is not reflected by this ratio.
