The Kuangda Technology Group Co., Ltd. (SZSE:002516) share price has fared very poorly over the last month, falling by a substantial 26%. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 34% in that time.

In spite of the heavy fall in price, you could still be forgiven for feeling indifferent about Kuangda Technology Group's P/E ratio of 27.6x, since the median price-to-earnings (or "P/E") ratio in China is also close to 28x. While this might not raise any eyebrows, if the P/E ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

As an illustration, earnings have deteriorated at Kuangda Technology Group over the last year, which is not ideal at all. One possibility is that the P/E is moderate because investors think the company might still do enough to be in line with the broader market in the near future. If not, then existing shareholders may be a little nervous about the viability of the share price.

Does Growth Match The P/E?

In order to justify its P/E ratio, Kuangda Technology Group would need to produce growth that's similar to the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 5.4%. This has soured the latest three-year period, which nevertheless managed to deliver a decent 7.8% overall rise in EPS. So we can start by confirming that the company has generally done a good job of growing earnings over that time, even though it had some hiccups along the way.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 41% shows it's noticeably less attractive on an annualised basis.

In light of this, it's curious that Kuangda Technology Group's P/E sits in line with the majority of other companies. Apparently many investors in the company are less bearish than recent times would indicate and aren't willing to let go of their stock right now. Maintaining these prices will be difficult to achieve as a continuation of recent earnings trends is likely to weigh down the shares eventually.
