Vertex Corporation's (TSE:5290) Shares Climb 33% But Its Business Is Yet to Catch Up

Vertex Corporation (TSE:5290) shareholders would be excited to see that the share price has had a great month, posting a 33% gain and recovering from prior weakness. The last 30 days bring the annual gain to a very sharp 46%.

After such a large jump in price, Vertex may be sending bearish signals at the moment with its price-to-earnings (or "P/E") ratio of 16.1x, since almost half of all companies in Japan have P/E ratios under 13x and even P/E's lower than 9x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

For instance, Vertex's receding earnings in recent times would have to be some food for thought. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/E from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Is There Enough Growth For Vertex?

The only time you'd be truly comfortable seeing a P/E as high as Vertex's is when the company's growth is on track to outshine the market.

Retrospectively, the last year delivered a frustrating 4.5% decrease to the company's bottom line. As a result, earnings from three years ago have also fallen 11% overall. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Comparing that to the market, which is predicted to deliver 11% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

With this information, we find it concerning that Vertex is trading at a P/E higher than the market. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the recent negative growth rates.

The Final Word

Vertex's P/E is getting right up there since its shares have risen strongly. 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.

Our examination of Vertex revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. Right now we are increasingly uncomfortable with the high P/E as this earnings performance is highly unlikely to support such positive sentiment for long. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
