American Coastal Insurance Corporation (NASDAQ:ACIC) shares have had a really impressive month, gaining 26% after a shaky period beforehand. The last 30 days bring the annual gain to a very sharp 96%.

In spite of the firm bounce in price, American Coastal Insurance may still be sending very bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 7.6x, since almost half of all companies in the United States have P/E ratios greater than 20x and even P/E's higher than 36x 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.

Recent times have been advantageous for American Coastal Insurance as its earnings have been rising faster than most other companies. It might be that many expect the strong earnings performance to degrade substantially, which has repressed the P/E. If not, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

Does Growth Match The Low P/E?

American Coastal Insurance's P/E ratio would be typical for a company that's expected to deliver very poor growth or even falling earnings, and importantly, perform much worse than the market.

If we review the last year of earnings growth, the company posted a worthy increase of 14%. Still, EPS has barely risen at all in aggregate from three years ago, which is not ideal. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Shifting to the future, estimates from the only analyst covering the company suggest earnings growth is heading into negative territory, declining 16% over the next year. With the market predicted to deliver 15% growth , that's a disappointing outcome.

With this information, we are not surprised that American Coastal Insurance is trading at a P/E lower than the market. Nonetheless, there's no guarantee the P/E has reached a floor yet with earnings going in reverse. Even just maintaining these prices could be difficult to achieve as the weak outlook is weighing down the shares.

The Final Word

Shares in American Coastal Insurance are going to need a lot more upward momentum to get the company's P/E out of its slump. It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

We've established that American Coastal Insurance maintains its low P/E on the weakness of its forecast for sliding earnings, 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. It's hard to see the share price rising strongly in the near future under these circumstances.
