What Is Austal's (ASX:ASB) P/E Ratio After Its Share Price Tanked?

To the annoyance of some shareholders, Austal (ASX:ASB) shares are down a considerable 35% in the last month. The stock has been solid, longer term, gaining 12% in the last year.

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. Perhaps the simplest way to get a read on investors' expectations of a business 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. That means even if the current P/E is high, it will reduce over time if the share price stays flat. Then, a lower P/E should attract more buyers, pushing the share price up.

In the last year, Austal grew EPS like Taylor Swift grew her fan base back in 2010; the 106% gain was both fast and well deserved.

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

One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. In other words, it does not consider any debt or cash that the company may have on the balance sheet. 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.

So What Does Austal's Balance Sheet Tell Us?

Austal has net cash of AU$108m. This is fairly high at 10% of its market capitalization. That might mean balance sheet strength is important to the business, but should also help push the P/E a bit higher than it would otherwise be.

The Verdict On Austal's P/E Ratio

Austal's P/E is 11.6 which is below average (14.9) in the AU market. The net cash position gives plenty of options to the business, and the recent improvement in EPS is good to see. The relatively low P/E ratio implies the market is pessimistic. Given Austal's P/E ratio has declined from 17.9 to 11.6 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 don't like to trade against momentum, that could be a warning sign, but a contrarian investor might want to take a closer look.

Investors should be looking to buy stocks that the market is wrong about. 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.
