However, the P/S might be quite low for a reason and it requires further investigation to determine if it's justified.

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

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

If we review the last year of revenue growth, the company posted a terrific increase of 161%. The latest three year period has also seen an excellent 129% overall rise in revenue, aided by its short-term performance. Accordingly, shareholders would have definitely welcomed those medium-term rates of revenue growth.

Comparing that to the industry, which is predicted to deliver 35% growth in the next 12 months, the company's momentum is pretty similar based on recent medium-term annualised revenue results.
