<div id="readability-page-1"><div><p>Sugemalimab’s new Category I, A recommendation in European Society for Medical Oncology guidance for early and locally advanced non small cell lung cancer puts CStone Pharmaceuticals (SEHK:2616) firmly in focus for investors tracking oncology developments.</p> <p>See our latest analysis for CStone Pharmaceuticals.</p> <p>The ESMO endorsement arrives alongside strong recent trading, with the HK$10.07 share price supported by a 30 day share price return of 38.32% and a 1 year total shareholder return above 3x that. This suggests momentum and expectations around CStone’s oncology portfolio are building.</p> <p>If this kind of oncology driven momentum has your attention, it could be a good moment to scan for other healthcare names benefiting from AI in drug development using the 123 healthcare AI stocks</p> <p>With HK$10.07 per share, a 12 month total return above 300%, a large intrinsic value discount and a 41% gap to the average analyst target, the key question now is whether upside remains or expectations already reflect future growth.</p> <h2>Preferred Price to Sales Multiple of 47.9x: Is It Justified?</h2> <p>CStone is currently priced at HK$10.07, and the P/S ratio of 47.9x signals that investors are paying a high amount for each HK$ of revenue compared with the Hong Kong Biotechs industry and its direct peers.</p> <p>The P/S multiple looks at the company’s market value relative to its annual revenue, which can be useful for businesses that are still loss making. For CStone, this sits at 47.9x, versus 12.9x for the broader Hong Kong Biotechs group and 26.1x across its peer set. This indicates that the market is assigning a rich revenue multiple to an unprofitable company, even though Simply Wall St’s DCF model suggests the shares trade at a large discount to estimated future cash flows.</p> <p>That premium P/S level is far above both the sector and the estimated fair ratio of 10.3x. This is a level the market could potentially move closer to if sentiment or growth expectations shift. Given that earnings are currently negative and the company has a negative return on equity, the valuation is being driven more by revenue growth expectations and the oncology pipeline than by current profitability.</p> <p>Explore the SWS fair ratio for CStone Pharmaceuticals</p> <p><strong>Result: Preferred price to sales ratio of 47.9x (OVERVALUED).</strong></p> <p>However, current losses of CN¥437.003m and a rich 47.9x P/S multiple mean any setback in the oncology pipeline or guidance could quickly challenge this momentum.</p> <p>Find out about the key risks to this CStone Pharmaceuticals narrative.</p> <h2>Another View: What Does The SWS DCF Model Say?</h2> <p>While the current 47.9x P/S ratio points to a rich revenue multiple, the SWS DCF model paints a different picture, with HK$10.07 trading at a 71.7% discount to an estimated HK$35.62 future cash flow value. For you, that contrast raises a simple question: which story carries more weight?</p> <p>Look into how the SWS DCF model arrives at its fair value.</p> <figure><img height="476" src="https://imageproxy.pbkrs.com/https://images.simplywall.st/company/56778cc3-6de7-42ae-9dbc-9e00c5b208ed/chart/dcf/query-ZGF0ZT0yMDI2LTA0LTEx?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="746" original-src="https://imageproxy.pbkrs.com/https://images.simplywall.st/company/56778cc3-6de7-42ae-9dbc-9e00c5b208ed/chart/dcf/query-ZGF0ZT0yMDI2LTA0LTEx"/><figcaption>2616 Discounted Cash Flow as at Apr 2026</figcaption></figure><p>Simply Wall St performs a discounted cash flow (DCF) on every stock in the world every day (check out CStone Pharmaceuticals for example).
