Marsh McLennan (MMC): Valuation Check After Mizuho Initiation, Thrive Plan and $6 Billion Buyback

Mizuho’s new coverage on Marsh and McLennan Companies (MMC) spotlights three levers investors care about: ongoing margin gains, the Thrive restructuring plan, and a fresh 6 billion dollars buyback alongside expansion in Hawai’i.

See our latest analysis for Marsh & McLennan Companies.

Those moves come as the share price trades around 187.3 dollars, with a modest positive near term share price return but a weaker year to date backdrop. At the same time, multi year total shareholder returns still point to a solid long term compounding story and gradually rebuilding momentum.

If you like MMC’s steady compounding but want to see what else is out there, this is a good moment to explore fast growing stocks with high insider ownership.

With shares trading below analyst targets and a double digit intrinsic discount, investors face a familiar dilemma: is MMC quietly undervalued after a soft year, or is the market already baking in its next leg of growth?

Most Popular Narrative Narrative: 11.8% Undervalued
