With shares at record highs and the pipeline progressing rapidly, investors are left wondering: Does Avidity Biosciences still have room to run, or is future growth already fully reflected in today’s price?

Price-to-Book of 5.7x: Is it justified?

Avidity Biosciences trades at a price-to-book ratio of 5.7x, notably higher than the US Biotechs industry average of 2.6x. This suggests that investors are paying a hefty premium relative to the company’s net assets.

The price-to-book ratio measures how much investors are willing to pay per dollar of net assets. For biotechs, where tangible assets might not capture all intangible pipeline value, this ratio can help signal whether optimism about future breakthroughs is already reflected in the share price.

With the market valuing Avidity Biosciences at over double the industry average, there is a clear expectation of significant future growth or breakthrough potential. This optimism does not appear to be explained by accounting metrics alone. If the sector returns to historical norms, this multiple could be at risk of falling.

Result: Price-to-Book of 5.7x (OVERVALUED)
