Those rapid fire regulatory wins have gone hand in hand with a powerful rerating, with Praxis posting a roughly 609% 3 month share price return and a 627% 3 year total shareholder return, suggesting momentum is clearly building around its CNS pipeline.

If you are looking beyond Praxis for what else could surprise to the upside in neurology and rare disease, this is a good moment to explore healthcare stocks.

With shares already up more than sixfold and analysts racing to lift price targets, does Praxis still offer mispriced optionality around its epilepsy and tremor pipeline, or is the market already discounting years of future growth?

Price-to-Book of 19.5x: Is it justified?

Praxis’s last close at $267.28 translates into a steep 19.5x price to book multiple, signaling that investors are paying a rich premium versus peers.

The price to book ratio compares a company’s market value with its net assets on the balance sheet, a common yardstick for asset light, R&D heavy biotechs. A 19.5x reading implies the market is assigning substantial value to Praxis’s future CNS pipeline cash flows despite its currently negative earnings and equity returns.

Given that Praxis is still unprofitable with a negative return on equity today and only forecast to reach modestly positive ROE in three years, such a lofty multiple suggests investors are front loading expectations for rapid revenue and earnings inflection. While our DCF work points to deep upside potential, the market is clearly already pricing in a sizeable share of those long dated growth assumptions via this elevated book value multiple.

Compared with the broader US biotech industry average of about 2.7x price to book and an already elevated 12x for close peers, Praxis’s 19.5x stands out as aggressively higher. This gap underscores how far sentiment has raced ahead of the sector norm, and signals that any disappointment around trial timelines or uptake could prompt a sharp reset from these premium valuation levels.

Result: Price to book of 19.5x (OVERVALUED).

However, setbacks in late stage CNS trials or slower than expected commercial uptake could quickly deflate sentiment and challenge today’s premium valuation.
