After a stellar run earlier this year, Amylyx Pharmaceuticals is still riding strong momentum. Its 1-month share price return is positive, and the 3-month share price return of nearly 74% hints at a substantial shift in sentiment despite some recent volatility. Over the last year, the 1-year total shareholder return of nearly 167% stands in sharp contrast to the challenging backdrop of the past three years, reflecting both fresh optimism and a cautious eye from investors.

With recent gains and analyst price targets suggesting further upside, the big question is whether Amylyx’s rapid rise still has room to run or if the market has already accounted for its future growth potential.

Price-to-Book Ratio of 9x: Is it justified?

Amylyx Pharmaceuticals trades at a price-to-book (P/B) ratio of 9x, significantly above the US Pharmaceuticals industry average of 2.2x and its peer average of 2.9x. With its last close at $14.17, this steep multiple raises questions about whether the market has become overly optimistic or is factoring in unique growth expectations not visible in sector peers.

The price-to-book ratio compares a company’s market value to its book value, offering a glimpse into how much investors are willing to pay for each dollar of net assets. This metric is especially relevant for pharmaceutical firms like Amylyx, where asset bases are heavily influenced by research, patents, and pipeline prospects rather than steady profits.

For Amylyx, the 9x P/B ratio signals a clear premium being placed on the company, possibly driven by its robust forecasted revenue growth and momentum in its therapeutic pipeline. At this level, the stock looks expensive compared to both the wider drugs industry and direct competitors. This might mean that expectations for rapid advancement or significant breakthroughs are already reflected in the share price.

Result: Price-to-Book of 9x (OVERVALUED)
