What Is Essex Bio-Technology's (HKG:1061) P/E Ratio After Its Share Price Rocketed?

Simply Wall St

Essex Bio-Technology (HKG:1061) shares have had a really impressive month, gaining 31%, after some slippage. And the full year gain of 23% isn't too shabby, either!

Assuming no other changes, a sharply higher share price makes a stock less attractive to potential buyers. 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 some would prefer to hold off buying when there is a lot of optimism towards a stock. 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). 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

Earnings growth rates have a big influence on P/E ratios. When earnings grow, the 'E' increases, over time. And in that case, the P/E ratio itself will drop rather quickly. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.

Notably, Essex Bio-Technology grew EPS by a whopping 35% in the last year. And earnings per share have improved by 34% annually, over the last five years. With that performance, I would expect it to have an above 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. 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).

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).

How Does Essex Bio-Technology's Debt Impact Its P/E Ratio?

Essex Bio-Technology has net cash of HK$129m. That should lead to a higher P/E than if it did have debt, because its strong balance sheets gives it more options.

The Bottom Line On Essex Bio-Technology's P/E Ratio

Essex Bio-Technology's P/E is 14.5 which is above average (10.3) in its market. Its net cash position is the cherry on top of its superb EPS growth. To us, this is the sort of company that we would expect to carry an above average price tag (relative to earnings). What is very clear is that the market has become more optimistic about Essex Bio-Technology over the last month, with the P/E ratio rising from 11.1 back then to 14.5 today. If you like to buy stocks that have recently impressed the market, then this one might be a candidate; but if you prefer to invest when there is 'blood in the streets', then you may feel the opportunity has passed.
