Aehr Test Systems' (NASDAQ:AEHR) 27% Share Price Surge Not Quite Adding Up

Despite an already strong run, Aehr Test Systems (NASDAQ:AEHR) shares have been powering on, with a gain of 27% in the last thirty days. But the last month did very little to improve the 67% share price decline over the last year.

Following the firm bounce in price, Aehr Test Systems may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 31.6x, 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. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

Aehr Test Systems has been doing a decent job lately as it's been growing earnings at a reasonable pace. It might be that many expect the reasonable 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.

Is There Enough Growth For Aehr Test Systems?

There's an inherent assumption that a company should far outperform the market for P/E ratios like Aehr Test Systems' to be considered reasonable.

If we review the last year of earnings growth, the company posted a worthy increase of 3.4%. Still, EPS has barely risen at all in aggregate from three years ago, which is not ideal. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 12% shows it's noticeably less attractive on an annualised basis.

In light of this, it's alarming that Aehr Test Systems' 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. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh heavily on the share price eventually.

The Key Takeaway

Aehr Test Systems' P/E is flying high just like its stock has during the last month. 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 Aehr Test Systems 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. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
