A Sliding Share Price Has Us Looking At Biffa plc's (LON:BIFF) P/E Ratio

Unfortunately for some shareholders, the Biffa (LON:BIFF) share price has dived 31% in the last thirty days. Even longer term holders have taken a real hit with the stock declining 14% 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

Generally speaking the rate of earnings growth has a profound impact on a company's P/E multiple. 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. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

Biffa's earnings per share fell by 26% in the last twelve months. And EPS is down 37% a year, over the last 5 years. This growth rate might warrant a below average P/E ratio.

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

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. In theory, a company can lower its future P/E ratio by using cash or debt to invest in 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 Biffa's Balance Sheet Tell Us?

Biffa's net debt equates to 48% of its market capitalization. While it's worth keeping this in mind, it isn't a worry.

The Verdict On Biffa's P/E Ratio

Biffa trades on a P/E ratio of 24.3, which is above its market average of 12.7. With a bit of debt, but a lack of recent growth, it's safe to say the market is expecting improved profit performance from the company, in the next few years. What can be absolutely certain is that the market has become significantly less optimistic about Biffa over the last month, with the P/E ratio falling from 35.1 back then to 24.3 today. 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.
