Alumis (ALMS) stock has been in focus after the company reported late breaking Phase 3 data for its oral TYK2 inhibitor envudeucitinib in moderate to severe plaque psoriasis, alongside weaker Q1 2026 revenue.

Despite the latest 1-day share price return falling 7.15% and shorter-term pressure, including a 30-day share price return down 8.48%, Alumis still shows very strong momentum over a longer horizon, with a 1-year total shareholder return of about 2.8x.

With the stock pulling back in the short term but delivering about a 2.8x total return over the past year, the key question now is whether Alumis is undervalued after recent data or if the market is already pricing in future growth.

Preferred Price to Book Multiple of 5.1x: Is it justified?

Alumis currently trades on a P/B ratio of 5.1x, which places a clear premium on the $22.87 share price compared with many peers in the sector.

P/B compares the company's market value to its book value, so for a clinical stage biopharmaceutical business that is still loss making, a higher ratio typically reflects investor focus on future pipeline potential rather than current profitability.

In this case, the market appears willing to pay more than 5 times the accounting value of Alumis's net assets, even though the company is unprofitable, is forecast to remain loss making over the next 3 years, has a negative return on equity and has seen shareholders substantially diluted over the past year.

That premium also stands out against both the US pharmaceuticals industry average P/B of 2.2x and the peer group average of 4.5x, which suggests investors are assigning Alumis a higher valuation multiple than many comparable stocks.

Result: Price-to-book of 5.1x (OVERVALUED)

However, there are clear risks, including ongoing losses, with net income at a loss of US$237.415 million and a market value of about US$2.9b resting on early stage assets.

Next Steps
