A Sliding Share Price Has Us Looking At Aerometrex Limited's (ASX:AMX) P/E Ratio

Simply Wall St

Unfortunately for some shareholders, the Aerometrex (ASX:AMX) share price has dived 38% in the last thirty days. Zooming out, the recent drop wiped out a year's worth of gains, with the share price now back where it was a year ago.

Assuming nothing else has changed, a lower share price makes a stock more attractive to potential buyers. While the market sentiment towards a stock is very changeable, in the long run, the share price will tend to move in the same direction as earnings per share. 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). 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

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. Therefore, even if you pay a high multiple of earnings now, that multiple will become lower in the future. Then, a lower P/E should attract more buyers, pushing the share price up.

Aerometrex saw earnings per share decrease by 20% last year. But EPS is up 77% over the last 5 years.

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. In other words, it does not consider any debt or cash that the company may have on the balance sheet. 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.

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.

How Does Aerometrex's Debt Impact Its P/E Ratio?

With net cash of AU$20m, Aerometrex has a very strong balance sheet, which may be important for its business. Having said that, at 15% of its market capitalization the cash hoard would contribute towards a higher P/E ratio.

The Bottom Line On Aerometrex's P/E Ratio

Aerometrex trades on a P/E ratio of 48.0, which is multiples above its market average of 15.7. The recent drop in earnings per share might keep value investors away, but the net cash position means the company has time to improve: and the high P/E suggests the market thinks it will. Given Aerometrex's P/E ratio has declined from 77.5 to 48.0 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.
