What Is Mobotix's (ETR:MBQ) P/E Ratio After Its Share Price Tanked?

Unfortunately for some shareholders, the Mobotix (ETR:MBQ) share price has dived 33% in the last thirty days. Indeed the recent decline has arguably caused some bitterness for shareholders who have held through the 45% drop over twelve months.

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). The implication here is that long term investors have an opportunity when expectations of a company are too low. 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 Does Mobotix's P/E Ratio Compare To Its Peers?

We can tell from its P/E ratio of 71.42 that there is some investor optimism about Mobotix. The image below shows that Mobotix has a significantly higher P/E than the average (15.4) P/E for companies in the electronic industry.

That means that the market expects Mobotix will outperform other companies in its industry. Clearly the market expects growth, but it isn't guaranteed. So investors should delve deeper. I like to check if company insiders have been buying or selling.

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. Earnings growth means that in the future the 'E' will be higher. 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.

In the last year, Mobotix grew EPS like Taylor Swift grew her fan base back in 2010; the 111% gain was both fast and well deserved. Unfortunately, earnings per share are down 4.3% a year, over 5 years.

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

Don't forget that the P/E ratio considers market capitalization. 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).

While growth expenditure doesn't always pay off, the point is that it is a good option to have; but one that the P/E ratio ignores.

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

Mobotix's net debt is 25% of its market cap. That's enough debt to impact the P/E ratio a little; so keep it in mind if you're comparing it to companies without debt.

The Verdict On Mobotix's P/E Ratio

Mobotix's P/E is 71.4 which suggests the market is more focussed on the future opportunity rather than the current level of earnings. While the company does use modest debt, its recent earnings growth is superb. So on this analysis a high P/E ratio seems reasonable. Given Mobotix's P/E ratio has declined from 107.1 to 71.4 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.
