A Rising Share Price Has Us Looking Closely At Hainan Meilan International Airport Company Limited's (HKG:357) P/E Ratio

Simply Wall St

The Hainan Meilan International Airport (HKG:357) share price has done well in the last month, posting a gain of 30%. But that gain wasn't enough to make shareholders whole, as the share price is still down 2.7% 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). Investors have optimistic expectations of companies with higher P/E ratios, compared to companies with lower P/E ratios.

How Growth Rates Impact P/E Ratios

Probably the most important factor in determining what P/E a company trades on is the earnings growth. If earnings are growing quickly, then the 'E' in the equation will increase faster than it would otherwise. And in that case, the P/E ratio itself will drop rather quickly. Then, a lower P/E should attract more buyers, pushing the share price up.

Hainan Meilan International Airport shrunk earnings per share by 3.3% last year. But it has grown its earnings per share by 10% per year over the last five years.

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. 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 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.

Is Debt Impacting Hainan Meilan International Airport's P/E?

Net debt is 50% of Hainan Meilan International Airport's market cap. While that's enough to warrant consideration, it doesn't really concern us.

The Verdict On Hainan Meilan International Airport's P/E Ratio

Hainan Meilan International Airport has a P/E of 5.2. That's below the average in the HK market, which is 10.6. With only modest debt, it's likely the lack of EPS growth at least partially explains the pessimism implied by the P/E ratio. What we know for sure is that investors are becoming less uncomfortable about Hainan Meilan International Airport's prospects, since they have pushed its P/E ratio from 4.0 to 5.2 over the last month. For those who like to invest in turnarounds, that might mean it's time to put the stock on a watchlist, or research it. But others might consider the opportunity to have passed.

When the market is wrong about a stock, it gives savvy investors an opportunity. If the reality for a company is not as bad as the P/E ratio indicates, then the share price should increase as the market realizes this. So this free visualization of the analyst consensus on future earnings could help you make the right decision about whether to buy, sell, or hold.
