Sustainion Group AB's (NGM:SUSG) 26% Share Price Surge Not Quite Adding Up

Sustainion Group AB (NGM:SUSG) shareholders would be excited to see that the share price has had a great month, posting a 26% gain and recovering from prior weakness. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 12% over that time.

Since its price has surged higher, Sustainion Group's price-to-earnings (or "P/E") ratio of 62.4x might make it look like a strong sell right now compared to the market in Sweden, where around half of the companies have P/E ratios below 21x and even P/E's below 12x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

Recent times have been quite advantageous for Sustainion Group as its earnings have been rising very briskly. It seems that many are expecting the strong earnings performance to beat most other companies over the coming period, which has increased investors’ willingness to pay up for the stock. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Sustainion Group's Growth Trending?

Sustainion Group's P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 348% last year. Although, its longer-term performance hasn't been as strong with three-year EPS growth being relatively non-existent overall. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

Comparing that to the market, which is predicted to deliver 24% growth in the next 12 months, the company's momentum is weaker based on recent medium-term annualised earnings results.

In light of this, it's alarming that Sustainion Group's P/E sits above the majority of other companies. It seems most investors are ignoring the fairly limited recent growth rates and are hoping for a turnaround in the company's business prospects. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with recent growth rates.

The Bottom Line On Sustainion Group's P/E

Sustainion Group's P/E is flying high just like its stock has during the last month. It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

We've established that Sustainion Group currently trades on a much higher than expected P/E since its recent three-year growth is lower than the wider market forecast. Right now we are increasingly uncomfortable with the high P/E as this earnings performance isn't likely to support such positive sentiment for long. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
