TES Co., Ltd's (KOSDAQ:095610) 33% Share Price Surge Not Quite Adding Up

TES Co., Ltd (KOSDAQ:095610) shareholders would be excited to see that the share price has had a great month, posting a 33% gain and recovering from prior weakness. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 15% in the last twelve months.

Following the firm bounce in price, TES' price-to-earnings (or "P/E") ratio of 21.2x might make it look like a strong sell right now compared to the market in Korea, where around half of the companies have P/E ratios below 11x and even P/E's below 6x are quite common. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

As an illustration, earnings have deteriorated at TES over the last year, which is not ideal at all. 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. If not, then existing shareholders may be quite nervous about the viability of the share price.

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

There's an inherent assumption that a company should far outperform the market for P/E ratios like TES' to be considered reasonable.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 2.4%. This means it has also seen a slide in earnings over the longer-term as EPS is down 74% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 34% shows it's an unpleasant look.

In light of this, it's alarming that TES' P/E sits above the majority of other companies. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh heavily on the share price eventually.

The Final Word

Shares in TES have built up some good momentum lately, which has really inflated its P/E. While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

We've established that TES currently trades on a much higher than expected P/E since its recent earnings have been in decline over the medium-term. 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. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.

We don't want to rain on the parade too much, but we did also find 3 warning signs for TES (2 shouldn't be ignored!) that you need to be mindful of.
