What Amulaire Thermal Technology, Inc.'s (TWSE:2241) 30% Share Price Gain Is Not Telling You

Amulaire Thermal Technology, Inc. (TWSE:2241) shares have continued their recent momentum with a 30% gain in the last month alone. Looking back a bit further, it's encouraging to see the stock is up 42% in the last year.

After such a large jump in price, given around half the companies in Taiwan's Auto Components industry have price-to-sales ratios (or "P/S") below 1.8x, you may consider Amulaire Thermal Technology as a stock to avoid entirely with its 5.6x P/S ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/S.

How Has Amulaire Thermal Technology Performed Recently?

With revenue growth that's exceedingly strong of late, Amulaire Thermal Technology has been doing very well. It seems that many are expecting the strong revenue performance to beat most other companies over the coming period, which has increased investors’ willingness to pay up for the stock. If not, then existing shareholders might be a little nervous about the viability of the share price.

What Are Revenue Growth Metrics Telling Us About The High P/S?

There's an inherent assumption that a company should far outperform the industry for P/S ratios like Amulaire Thermal Technology's to be considered reasonable.

Retrospectively, the last year delivered an exceptional 37% gain to the company's top line. Although, its longer-term performance hasn't been as strong with three-year revenue growth being relatively non-existent overall. Therefore, it's fair to say that revenue growth has been inconsistent recently for the company.

Comparing the recent medium-term revenue trends against the industry's one-year growth forecast of 8.0% shows it's noticeably less attractive.

In light of this, it's alarming that Amulaire Thermal Technology's P/S sits above the majority of other companies. It seems most investors are ignoring the fairly limited recent growth rates and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent revenue trends is likely to weigh heavily on the share price eventually.

What Does Amulaire Thermal Technology's P/S Mean For Investors?

The strong share price surge has lead to Amulaire Thermal Technology's P/S soaring as well. We'd say the price-to-sales ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

The fact that Amulaire Thermal Technology currently trades on a higher P/S relative to the industry is an oddity, since its recent three-year growth is lower than the wider industry forecast. Right now we aren't comfortable with the high P/S as this revenue performance isn't likely to support such positive sentiment for long. Unless there is a significant improvement in the company's medium-term performance, it will be difficult to prevent the P/S ratio from declining to a more reasonable level.
