Shenglan Technology Co., Ltd.'s (SZSE:300843) 50% Share Price Surge Not Quite Adding Up

Shenglan Technology Co., Ltd. (SZSE:300843) shareholders would be excited to see that the share price has had a great month, posting a 50% gain and recovering from prior weakness. The last 30 days bring the annual gain to a very sharp 64%.

Following the firm bounce in price, Shenglan Technology may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 61.7x, since almost half of all companies in China have P/E ratios under 33x and even P/E's lower than 20x 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.

With earnings growth that's exceedingly strong of late, Shenglan Technology has been doing very well. 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.

Does Growth Match The High P/E?

Shenglan Technology'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.

If we review the last year of earnings growth, the company posted a terrific increase of 31%. Still, incredibly EPS has fallen 27% in total from three years ago, which is quite disappointing. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

In contrast to the company, the rest of the market is expected to grow by 37% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

In light of this, it's alarming that Shenglan Technology's P/E sits above the majority of other companies. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. 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 Bottom Line On Shenglan Technology's P/E

The strong share price surge has got Shenglan Technology's P/E rushing to great heights as well. 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.

Our examination of Shenglan Technology 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.
