Lucas GC Limited (NASDAQ:LGCL) shareholders would be excited to see that the share price has had a great month, posting a 27% gain and recovering from prior weakness. Still, the 30-day jump doesn't change the fact that longer term shareholders have seen their stock decimated by the 73% share price drop in the last twelve months.

Even after such a large jump in price, Lucas GC's price-to-earnings (or "P/E") ratio of 8.8x might still make it look like a strong buy right now compared to the market in the United States, where around half of the companies have P/E ratios above 18x and even P/E's above 33x are quite common. However, the P/E might be quite low for a reason and it requires further investigation to determine if it's justified.

As an illustration, earnings have deteriorated at Lucas GC over the last year, which is not ideal at all. It might be that many expect the disappointing earnings performance to continue or accelerate, which has repressed the P/E. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

Is There Any Growth For Lucas GC?

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

Retrospectively, the last year delivered a frustrating 50% decrease to the company's bottom line. This has erased any of its gains during the last three years, with practically no change in EPS being achieved in total. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

This is in contrast to the rest of the market, which is expected to grow by 13% over the next year, materially higher than the company's recent medium-term annualised growth rates.

With this information, we can see why Lucas GC is trading at a P/E lower than the market. Apparently many shareholders weren't comfortable holding on to something they believe will continue to trail the bourse.

The Bottom Line On Lucas GC's P/E

Shares in Lucas GC are going to need a lot more upward momentum to get the company's P/E out of its slump. Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

As we suspected, our examination of Lucas GC revealed its three-year earnings trends are contributing to its low P/E, given they look worse than current market expectations. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
