The Abbisko Cayman Limited (HKG:2256) share price has done very well over the last month, posting an excellent gain of 60%. The last month tops off a massive increase of 185% in the last year.

Although its price has surged higher, you could still be forgiven for feeling indifferent about Abbisko Cayman's P/S ratio of 8.9x, since the median price-to-sales (or "P/S") ratio for the Biotechs industry in Hong Kong is also close to 9.8x. While this might not raise any eyebrows, if the P/S ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

Is There Some Revenue Growth Forecasted For Abbisko Cayman?

In order to justify its P/S ratio, Abbisko Cayman would need to produce growth that's similar to the industry.

Retrospectively, the last year delivered an explosive gain to the company's top line. The latest three year period has also seen an incredible overall rise in revenue, aided by its incredible short-term performance. So we can start by confirming that the company has done a tremendous job of growing revenue over that time.

Looking ahead now, revenue is anticipated to slump, contracting by 6.2% per year during the coming three years according to the four analysts following the company. Meanwhile, the broader industry is forecast to expand by 53% per annum, which paints a poor picture.

With this in consideration, we think it doesn't make sense that Abbisko Cayman's P/S is closely matching its industry peers. Apparently many investors in the company reject the analyst cohort's pessimism and aren't willing to let go of their stock right now. Only the boldest would assume these prices are sustainable as these declining revenues are likely to weigh on the share price eventually.
