When close to half the companies in the United States have price-to-earnings ratios (or "P/E's") below 17x, you may consider Ameren Corporation (NYSE:AEE) as a stock to potentially avoid with its 21.2x P/E ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.
There hasn't been much to differentiate Ameren's and the market's earnings growth lately. It might be that many expect the mediocre earnings performance to strengthen positively, which has kept the P/E from falling. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

There's an inherent assumption that a company should outperform the market for P/E ratios like Ameren's to be considered reasonable.
Retrospectively, the last year delivered a decent 3.8% gain to the company's bottom line. The latest three year period has also seen a 14% overall rise in EPS, aided somewhat by its short-term performance. So we can start by confirming that the company has actually done a good job of growing earnings over that time.
Looking ahead now, EPS is anticipated to climb by 9.1% per year during the coming three years according to the ten analysts following the company. That's shaping up to be similar to the 10% per year growth forecast for the broader market.
In light of this, it's curious that Ameren's P/E sits above the majority of other companies. It seems most investors are ignoring the fairly average growth expectations and are willing to pay up for exposure to the stock. Although, additional gains will be difficult to achieve as this level of earnings growth is likely to weigh down the share price eventually.
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.
Our examination of Ameren's analyst forecasts revealed that its market-matching earnings outlook isn't impacting its high P/E as much as we would have predicted. When we see an average earnings outlook with market-like growth, we suspect the share price is at risk of declining, sending the high P/E lower. Unless these conditions improve, it's challenging to accept these prices as being reasonable.
You need to take note of risks, for example - Ameren has 2 warning signs (and 1 which is potentially serious) we think you should know about.
It's important to make sure you look for a great company, not just the first idea you come across. So take a peek at this free list of interesting companies with strong recent earnings growth (and a low P/E).
