There's Reason For Concern Over Kaiser Aluminum Corporation's (NASDAQ:KALU) Massive 35% Price Jump

Kaiser Aluminum Corporation (NASDAQ:KALU) shareholders would be excited to see that the share price has had a great month, posting a 35% gain and recovering from prior weakness. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 27% in the last twelve months.

Following the firm bounce in price, Kaiser Aluminum may be sending bearish signals at the moment with its price-to-earnings (or "P/E") ratio of 23.2x, since almost half of all companies in the United States have P/E ratios under 18x and even P/E's lower than 10x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

AI is about to change healthcare. These 20 stocks are working on everything from early diagnostics to drug discovery. The best part - they are all under $10bn in marketcap - there is still time to get in early.

It looks like earnings growth has deserted Kaiser Aluminum recently, which is not something to boast about. It might be that many are expecting an improvement to the uninspiring earnings performance over the coming period, which has kept the P/E from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Does Growth Match The High P/E?

Kaiser Aluminum's P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the market.

If we review the last year of earnings, the company posted a result that saw barely any deviation from a year ago. The longer-term trend has been no better as the company has no earnings growth to show for over the last three years either. So it seems apparent to us that the company has struggled to grow earnings meaningfully over that time.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 13% shows it's noticeably less attractive on an annualised basis.

With this information, we find it concerning that Kaiser Aluminum is trading at a P/E higher than the market. It seems most investors are ignoring the fairly limited recent growth rates and are hoping for a turnaround in the company's business prospects. 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

Kaiser Aluminum shares have received a push in the right direction, but its P/E is elevated too. Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the 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. Right now we are increasingly uncomfortable with the high P/E as this earnings performance isn't likely to support such positive sentiment for long. 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.
