Price-to-Sales Ratio of 41.7x: Is it justified?

At a last close of HK$6.26, CStone Pharmaceuticals trades at a premium to both peers and industry benchmarks, as highlighted by its high price-to-sales ratio.

The price-to-sales (P/S) ratio compares a company’s market value to its annual revenue and is particularly relevant for growth-stage biotechs where profits may not yet be realized. For CStone, an elevated P/S ratio draws attention to the market’s expectation for future growth and revenue increases, even if current earnings are negative.

Compared to a peer average of 15.6x and an industry average of 14.3x, CStone’s 41.7x multiple stands well above the norm. In addition, the “fair” P/S ratio based on regression analysis is just 3.5x, suggesting the market may be pricing in more growth than the fundamentals support. This indicates that current optimism is higher than both market and sector averages and could adjust if financial performance does not align with expectations.
