Alphamab Oncology (HKG:9966) Shares Fly 35% But Investors Aren't Buying For Growth

Alphamab Oncology (HKG:9966) shares have continued their recent momentum with a 35% gain in the last month alone. The last 30 days were the cherry on top of the stock's 404% gain in the last year, which is nothing short of spectacular.

Although its price has surged higher, Alphamab Oncology's price-to-sales (or "P/S") ratio of 14.1x might still make it look like a buy right now compared to the Biotechs industry in Hong Kong, where around half of the companies have P/S ratios above 18.7x and even P/S above 68x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/S.

What Does Alphamab Oncology's P/S Mean For Shareholders?

Alphamab Oncology certainly has been doing a good job lately as it's been growing revenue more than most other companies. One possibility is that the P/S ratio is low because investors think this strong revenue performance might be less impressive moving forward. If the company manages to stay the course, then investors should be rewarded with a share price that matches its revenue figures.

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

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

Taking a look back first, we see that the company grew revenue by an impressive 207% last year. Pleasingly, revenue has also lifted 294% in aggregate from three years ago, thanks to the last 12 months of growth. So we can start by confirming that the company has done a great job of growing revenue over that time.

Looking ahead now, revenue is anticipated to climb by 19% each year during the coming three years according to the sole analyst following the company. With the industry predicted to deliver 58% growth per annum, the company is positioned for a weaker revenue result.

With this in consideration, its clear as to why Alphamab Oncology's P/S is falling short industry peers. It seems most investors are expecting to see limited future growth and are only willing to pay a reduced amount for the stock.

The Final Word

The latest share price surge wasn't enough to lift Alphamab Oncology's P/S close to the industry median. While the price-to-sales ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of revenue expectations.

We've established that Alphamab Oncology maintains its low P/S on the weakness of its forecast growth being lower than the wider industry, as expected. Shareholders' pessimism on the revenue prospects for the company seems to be the main contributor to the depressed P/S. Unless these conditions improve, they will continue to form a barrier for the share price around these levels.
