Molina Healthcare, Inc. (NYSE:MOH) shares have had a horrible month, losing 31% after a relatively good period beforehand. For any long-term shareholders, the last month ends a year to forget by locking in a 54% share price decline.

Following the heavy fall in price, Molina Healthcare may be sending bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 13.7x, since almost half of all companies in the United States have P/E ratios greater than 20x and even P/E's higher than 35x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's limited.

While the market has experienced earnings growth lately, Molina Healthcare's earnings have gone into reverse gear, which is not great. The P/E is probably low because investors think this poor earnings performance isn't going to get any better. If you still 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.

Does Growth Match The Low P/E?

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

Retrospectively, the last year delivered a frustrating 57% decrease to the company's bottom line. The last three years don't look nice either as the company has shrunk EPS by 33% in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Shifting to the future, estimates from the analysts covering the company suggest earnings should grow by 21% per year over the next three years. Meanwhile, the rest of the market is forecast to only expand by 12% per year, which is noticeably less attractive.

With this information, we find it odd that Molina Healthcare is trading at a P/E lower than the market. Apparently some shareholders are doubtful of the forecasts and have been accepting significantly lower selling prices.

What We Can Learn From Molina Healthcare's P/E?

Molina Healthcare's recently weak share price has pulled its P/E below most other companies. 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 Molina Healthcare currently trades on a much lower than expected P/E since its forecast growth is higher than the wider market. There could be some major unobserved threats to earnings preventing the P/E ratio from matching the positive outlook. It appears many are indeed anticipating earnings instability, because these conditions should normally provide a boost to the share price.

Of course, you might find a fantastic investment by looking at a few good candidates. So take a peek at this free list of companies with a strong growth track record, trading on a low P/E.
