Some Confidence Is Lacking In Kaiser Aluminum Corporation's (NASDAQ:KALU) P/E

With a price-to-earnings (or "P/E") ratio of 24.5x Kaiser Aluminum Corporation (NASDAQ:KALU) may be sending bearish signals at the moment, given that almost half of all companies in the United States have P/E ratios under 18x and even P/E's lower than 11x 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 as high as it is.

With earnings growth that's exceedingly strong of late, Kaiser Aluminum has been doing very well. It seems that many are expecting the strong earnings performance to beat most other companies over the coming period, which has increased investors’ willingness to pay up for the stock. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Does Growth Match The High P/E?

In order to justify its P/E ratio, Kaiser Aluminum would need to produce impressive growth in excess of the market.

If we review the last year of earnings growth, the company posted a terrific increase of 255%. Still, EPS has barely risen at all from three years ago in total, which is not ideal. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

This is in contrast to the rest of the market, which is expected to grow by 15% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's alarming that Kaiser Aluminum's P/E sits above the majority of other companies. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with recent growth rates.

The Key Takeaway

Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

We've established that Kaiser Aluminum currently trades on a much higher than expected P/E since its recent three-year growth is lower than the wider market forecast. When we see weak earnings with slower than market growth, we suspect the share price is at risk of declining, sending the high P/E lower. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
