Coherent Corp.'s (NYSE:COHR) 26% Share Price Surge Not Quite Adding Up

Coherent Corp. (NYSE:COHR) shares have continued their recent momentum with a 26% gain in the last month alone. The last 30 days bring the annual gain to a very sharp 25%.

Even after such a large jump in price, there still wouldn't be many who think Coherent's price-to-sales (or "P/S") ratio of 2.9x is worth a mention when the median P/S in the United States' Electronic industry is similar at about 2.4x. Although, it's not wise to simply ignore the P/S without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

What Does Coherent's Recent Performance Look Like?

Recent times have been advantageous for Coherent as its revenues have been rising faster than most other companies. It might be that many expect the strong revenue performance to wane, which has kept the P/S ratio from rising. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's not quite in favour.

How Is Coherent's Revenue Growth Trending?

The only time you'd be comfortable seeing a P/S like Coherent's is when the company's growth is tracking the industry closely.

Taking a look back first, we see that the company grew revenue by an impressive 23% last year. The latest three year period has also seen an excellent 75% overall rise in revenue, aided by its short-term performance. So we can start by confirming that the company has done a great job of growing revenue over that time.

Shifting to the future, estimates from the analysts covering the company suggest revenue should grow by 9.8% each year over the next three years. That's shaping up to be materially lower than the 13% each year growth forecast for the broader industry.

In light of this, it's curious that Coherent's P/S sits in line with the majority of other companies. Apparently many investors in the company are less bearish than analysts indicate and aren't willing to let go of their stock right now. Maintaining these prices will be difficult to achieve as this level of revenue growth is likely to weigh down the shares eventually.

The Bottom Line On Coherent's P/S

Coherent appears to be back in favour with a solid price jump bringing its P/S back in line with other companies in the industry Using the price-to-sales ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

When you consider that Coherent's revenue growth estimates are fairly muted compared to the broader industry, it's easy to see why we consider it unexpected to be trading at its current P/S ratio. When we see companies with a relatively weaker revenue outlook compared to the industry, we suspect the share price is at risk of declining, sending the moderate P/S lower. Circumstances like this present a risk to current and prospective investors who may see share prices fall if the low revenue growth impacts the sentiment.
