CircuTech International Holdings Limited (HKG:8051) shareholders would be excited to see that the share price has had a great month, posting a 38% gain and recovering from prior weakness. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 14% in the last twelve months.

Since its price has surged higher, CircuTech International Holdings may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 16.9x, since almost half of all companies in Hong Kong have P/E ratios under 9x and even P/E's lower than 6x are not unusual. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

For example, consider that CircuTech International Holdings' financial performance has been pretty ordinary lately as earnings growth is non-existent. It might be that many are expecting an improvement to the uninspiring earnings performance over the coming period, which has kept the P/E from collapsing. If not, then existing shareholders may be a little nervous about the viability of the share price.

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

In order to justify its P/E ratio, CircuTech International Holdings would need to produce outstanding growth well in excess of the market.

Retrospectively, the last year delivered virtually the same number to the company's bottom line as the year before. Regardless, EPS has managed to lift by a handy 21% in aggregate from three years ago, thanks to the earlier period of growth. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 22% shows it's noticeably less attractive on an annualised basis.

In light of this, it's alarming that CircuTech International Holdings' 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. 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 Key Takeaway

The strong share price surge has got CircuTech International Holdings' P/E rushing to great heights as well. Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

We've established that CircuTech International Holdings 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.
