Erayak Power Solution Group Inc. (NASDAQ:RAYA) shareholders won't be pleased to see that the share price has had a very rough month, dropping 25% and undoing the prior period's positive performance. Longer-term shareholders will rue the drop in the share price, since it's now virtually flat for the year after a promising few quarters.

Since its price has dipped substantially, Erayak Power Solution Group may be sending very bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 6.7x, since almost half of all companies in the United States have P/E ratios greater than 16x and even P/E's higher than 33x are not unusual. However, the P/E might be quite low for a reason and it requires further investigation to determine if it's justified.

For instance, Erayak Power Solution Group's receding earnings in recent times would have to be some food for thought. One possibility is that the P/E is low because investors think the company won't do enough to avoid underperforming the broader market in the near future. 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.

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

In order to justify its P/E ratio, Erayak Power Solution Group would need to produce anemic growth that's substantially trailing the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 84%. 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 5.6% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's understandable that Erayak Power Solution Group's P/E sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on to something they believe will continue to trail the bourse.

What We Can Learn From Erayak Power Solution Group's P/E?

Shares in Erayak Power Solution Group have plummeted and its P/E is now low enough to touch the ground. We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

We've established that Erayak Power Solution Group maintains its low P/E on the weakness of its recent three-year growth being lower than the wider market forecast, as expected. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.

Having said that, be aware Erayak Power Solution Group is showing 3 warning signs in our investment analysis, and 1 of those is potentially serious.
