Roche Holding recently reported positive Phase II results for CT-388, its once-weekly dual GLP-1/GIP obesity drug candidate, showing clinically meaningful placebo-adjusted weight loss and favorable tolerability over 48 weeks.

The data suggest CT-388 could become an important pillar in Roche’s expanding cardiometabolic portfolio, complementing its diagnostics capabilities in managing obesity-related health risks.

We’ll now examine how CT-388’s Phase II success, and its potential move into late-stage trials, shapes Roche’s investment narrative.

We’ve found 14 US stocks that are forecast to pay a dividend yield of over 6% next year. See the full list for free.

For me, the core Roche story is about backing a diversified healthcare group that is leaning on a deep pipeline, high return on equity and a long record of growing dividends, even as it works through mixed earnings trends and a high debt load. The latest CT-388 Phase II success adds a fresh cardiometabolic growth option, but the share price reaction so far has been measured, suggesting investors still see nearer term catalysts anchored in execution on late stage oncology and immunology launches, delivery against Roche’s mid single digit sales and high single digit EPS guidance for 2026, and how pricing pressures in diagnostics and products like Xolair evolve. CT-388 now sits alongside those factors as a meaningful, but still early, piece of the puzzle rather than the main driver.

However, one risk stands out that shareholders may not be fully focusing on yet. Despite retreating, Roche Holding’s shares might still be trading above their fair value and there could be some more downside. Discover how much.
