Optimistic Investors Push Zymeworks Inc. (NASDAQ:ZYME) Shares Up 25% But Growth Is Lacking

The Zymeworks Inc. (NASDAQ:ZYME) share price has done very well over the last month, posting an excellent gain of 25%. The last 30 days bring the annual gain to a very sharp 30%. Although its price has surged higher, there still wouldn't be many who think Zymeworks' price-to-sales (or "P/S") ratio of 9.2x is worth a mention when it essentially matches the median P/S in the United States' Biotechs industry. 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.

Zymeworks' P/S ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with the industry. Retrospectively, the last year delivered an exceptional 96% gain to the company's top line. Pleasingly, revenue has also lifted 289% in aggregate from three years ago, thanks to the last 12 months of growth. Therefore, it's fair to say the revenue growth recently has been superb for the company. Turning to the outlook, the next three years should generate growth of 7.1% each year as estimated by the eight analysts watching the company. Meanwhile, the rest of the industry is forecast to expand by 119% each year, which is noticeably more attractive. With this information, we find it interesting that Zymeworks is trading at a fairly similar P/S compared to the industry. It seems most investors are ignoring the fairly limited growth expectations and are willing to pay up for exposure to the stock. These shareholders may be setting themselves up for future disappointment if the P/S falls to levels more in line with the growth outlook. The Key Takeaway Zymeworks appears to be back in favour with a solid price jump bringing its P/S back in line with other companies in the industry It's argued the price-to-sales ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator. Given that Zymeworks' revenue growth projections are relatively subdued in comparison to the wider industry, it comes as a surprise to see it 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.
