There's Reason For Concern Over Synopex Inc.'s (KOSDAQ:025320) Massive 26% Price Jump

Despite an already strong run, Synopex Inc. (KOSDAQ:025320) shares have been powering on, with a gain of 26% in the last thirty days. This latest share price bounce rounds out a remarkable 301% gain over the last twelve months.

Following the firm bounce in price, Synopex may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 61.3x, since almost half of all companies in Korea have P/E ratios under 12x and even P/E's lower than 7x are not unusual. 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 Synopex as its earnings have been rising very briskly. The P/E is probably high because investors think this strong earnings growth will be enough to outperform the broader market in the near future. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

What Are Growth Metrics Telling Us About The High P/E?

Synopex'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 89% last year. However, the latest three year period hasn't been as great in aggregate as it didn't manage to provide any growth at all. 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 33% 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 Synopex'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 Key Takeaway

Shares in Synopex have built up some good momentum lately, which has really inflated its P/E. We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

We've established that Synopex 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. 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.
