When close to half the companies in the United States have price-to-earnings ratios (or "P/E's") above 19x, you may consider Ardmore Shipping Corporation (NYSE:ASC) as a highly attractive investment with its 4.8x P/E ratio. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so limited.

With earnings that are retreating more than the market's of late, Ardmore Shipping has been very sluggish. It seems that many are expecting the dismal earnings performance to persist, which has repressed the P/E. You'd much rather the company wasn't bleeding earnings if you still believe in the business. Or at the very least, you'd be hoping the earnings slide doesn't get any worse if your plan is to pick up some stock while it's out of favour.

Is There Any Growth For Ardmore Shipping?

Ardmore Shipping'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.

Retrospectively, the last year delivered a frustrating 21% 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.

Shifting to the future, estimates from the four analysts covering the company suggest earnings growth is heading into negative territory, declining 20% each year over the next three years. With the market predicted to deliver 10% growth per year, that's a disappointing outcome.

In light of this, it's understandable that Ardmore Shipping's P/E would sit below the majority of other companies. Nonetheless, there's no guarantee the P/E has reached a floor yet with earnings going in reverse. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

The Final Word

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.

As we suspected, our examination of Ardmore Shipping's analyst forecasts revealed that its outlook for shrinking earnings is contributing to its low P/E. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. It's hard to see the share price rising strongly in the near future under these circumstances.
