Despite an already strong run, Launch Tech Company Limited (HKG:2488) shares have been powering on, with a gain of 37% in the last thirty days. The last 30 days bring the annual gain to a very sharp 94%.

Even after such a large jump in price, you could still be forgiven for feeling indifferent about Launch Tech's P/E ratio of 8.8x, since the median price-to-earnings (or "P/E") ratio in Hong Kong is also close to 10x. 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 Launch Tech 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?

Launch Tech's P/E ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with the market.

Retrospectively, the last year delivered a frustrating 48% decrease to the company's bottom line. At least EPS has managed not to go completely backwards from three years ago in aggregate, thanks to the earlier period of growth. 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 21% growth in the next 12 months, the company's momentum is weaker based on recent medium-term annualised earnings results.

With this information, we find it interesting that Launch Tech is trading at a fairly similar P/E to the market. 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.

The Key Takeaway

Launch Tech's stock has a lot of momentum behind it lately, which has brought its P/E level with the market. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

We've established that Launch Tech currently trades on a higher than expected P/E since its recent three-year growth is lower than the wider market forecast. Right now we are uncomfortable with the P/E as this earnings performance isn't likely to support a more positive sentiment for long. Unless the recent medium-term conditions improve, it's challenging to accept these prices as being reasonable.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 3 warning signs with Launch Tech (at least 1 which makes us a bit uncomfortable), and understanding these should be part of your investment process.
