MSCI (MSCI) is back in focus after its May 2026 Equity Index Review set out additions and deletions across flagship benchmarks, a routine reshuffle that can still matter for passive fund flows and regional markets.

The May index review headlines arrive at a time when MSCI’s stock has eased back in the very short term, with the 1 day share price return down 1.75% and the 7 day share price return down 1.93%. However, the 90 day share price return of 9.32% and 3 year total shareholder return of 27.97% point to momentum that has generally been constructive rather than fading.

If this index reshuffle has you thinking more broadly about structural themes in markets, it could be a suitable moment to scan for other index and data providers or exchanges with strong growth angles, starting with our screener of 20 top founder-led companies

With MSCI trading at US$570.91 and sitting around a 20% discount to the average analyst price target, plus an indicated intrinsic discount of about 9%, the key question is whether this is genuine value or if markets are already reflecting future growth.

Most Popular Narrative: 113.8% Overvalued

According to Esteban's narrative, MSCI's fair value sits at $267, which is well below the last close of $570.91, setting up a clear valuation gap for readers to weigh.

MSCI is a Wide Moat compounding machine whose index benchmarks serve as the institutional standard for $16.5 trillion in global AUM, generating 75%+ recurring revenue at 93-95% retention rates and approximately 50% FCF margins. The investment thesis rests on three durable pillars: (1) permanent switching costs in the Index segment, where fund mandate rewrites, LP notifications, and derivative contract renegotiations make benchmark migration prohibitively costly for all but the most determined sponsors; (2) secular tailwinds from the continued growth of passive investing and the institutionalization of private markets, which expand MSCI's AUM-linked revenue with zero incremental cost; and (3) an emerging private assets franchise replicating the Index playbook in a $10 trillion+ private equity and credit market that currently lacks institutional-grade benchmarks.

Curious how such strong margins and sticky cash flows still lead to a much lower fair value than today’s price? The key lies in how future growth, profitability and required returns are wired into this discounted cash flow narrative, and which long term assumptions tighten the gap between compounding power and valuation.

Result: Fair Value of $267 (OVERVALUED)

However, this story could be knocked off course if benchmark clients actively switch providers, or if regulation reshapes index usage and ESG demand.

Another View: Earnings Multiple Sends a Mixed Signal

Esteban’s $267 fair value leans heavily on cash flow assumptions, yet the current P/E of 31.5x tells a slightly different story. It sits below the US Capital Markets industry at 41.8x, but above peer average at 28.9x and the fair ratio of 16.5x, which points to meaningful valuation risk if sentiment cools.
