In late July, MSCI Inc. (MSCI) reported second quarter results that disappointed investors. Bookings in ESG and Analytics slowed and the stock dropped nearly 9%. The market’s reaction struck me as more of a repricing rather than a broken narrative. This gave me the opportunity to start a position in a business that has all the qualities of a compounding machine. The report showed that the Index segment continued to grow at its steady pace, margins held above sixty percent, and retention across businesses remained high. The optionality in ESG, Climate, and Private Assets was intact. Nothing about the long-term story changed.
Now, this may not be a name that many investors are familiar with. Most investors know the tickers that move markets. Fewer know the company that defines them. MSCI is one of those names. It provides the benchmarks, models, and data that shape how trillions of dollars are allocated. If you have owned an index fund, tracked a portfolio, or read an ESG rating, you have probably used something built by MSCI.
The thesis for MSCI is straightforward. It is a compounder because of its Index franchise. That segment generates close to 70% of profits and carries a wide moat built on entrenched client workflows, recurring revenues, and scale that is nearly impossible to replicate. The other businesses add growth opportunities and optionality with secular tailwinds, but they carry more uncertainty. This balance between its segments defines MSCI today and also explains why the stock trades at a premium.
A Moat Wasn’t Enough, MSCI Had to Learn Discipline
To understand how MSCI reached this point, it helps to take a step back. Prior to 2015, the business looked very different, reporting in three segments including Performance and Risk (combining what are now Index and Analytics, including early ESG data feeds), Governance (spun off in 2014) and Other (small data operations). While MSCI was a recognized name in indexes with sticky clients and growing revenue, it was not yet a great business. Margins were middling, the Analytics segment was bloated, and returns on capital hovered around 17%.
That changed when ValueAct Capital took a stake in 2015. The activist hedge fund saw what many did not. Beneath MSCI’s entrenched Index franchise was a company under-performing its potential. Rather than pushing for a quick spin-off, ValueAct pressed management to sharpen its focus and discipline.
The results were dramatic. Since then:
- MSCI doubled down on indexes, streamlined Analytics, and focused on new areas like ESG and private markets where secular growth trends were clear.
- Firm-wide EBITDA margins climbed from about 41% in 2014 to 60% today. Analytics went from inefficient and costly to running at nearly 50% margins.
- Free cash flow compounding north of $1.4 billion annually was funneled into selective acquisitions and aggressive buybacks, shrinking the share count by about 20% over a decade. Notably, this has left MSCI with negative equity, a financial quirk, but also a sign of management’s confidence in its cash flows.
- About two-thirds of revenue now comes from outside the United States, giving the company a more diversified base than many of its peers.
In short, instead of ValueAct reinvesting MSCI, they simply unlocked its potential. ROIC improved sharply to north of 25%, revenue growth became consistent, and free cash flow turned into a reliable compounding engine.
MSCI Segments: Compounding Depends on Index
The MSCI of 2025 reports four distinct business segments: Index, Analytics, ESG & Climate, and Private Assets. Each plays a role in the compounding story, but not all carry the same weight. The Index business is the compounding machine, Analytics has matured into a dependable contributor, while ESG and Private Assets offer upside optionality with more risk attached. Understanding how these pieces fit together is key to seeing why MSCI deserves the “compounder” label.
Index: Why The Business Matters (~57% of Revenue)
At the heart of MSCI is the Index business, and understanding it is the key to understanding the company itself.
If you have ever bought an ETF tracking global markets like the MSCI World or Emerging Markets you have encountered this franchise. This segment consistently generates about 57% of revenue and nearly 70% of profit, making it the company’s economic engine. Without this fortress, MSCI would not deserve the compounder label.
Performance and Scalability
Over the past five years, Index revenue has compounded at roughly 12% annually, growing from $1.02 billion in 2020 to $1.60 billion in 2024. Margins have held in the 75-76% range. As of Q2 2025, more than $2 trillion in ETF assets were benchmarked to MSCI indexes, up 24% from the year before. That scale reinforces the stickiness of the platform.
The predictability of MSCI’s Index revenue comes from two sources:
- Recurring subscription fees, which are paid annually by asset managers and institutions to access MSCI benchmarks.
- Asset-based fees, which are collected as ETFs and other funds track MSCI indexes, scaling naturally with global AUM growth.
Because building an index is largely an upfront cost, incremental revenue drops through at very high margins. That operating leverage explains why Index has powered MSCI’s transformation into a high-return compounding business.
A Fortress-Like Moat
The moat here is exceptionally wide. Switching away from an index provider is not like changing software vendors. It involves rewriting fund prospectuses, rebalancing portfolios, triggering tax liabilities, and risking client backlash. That explains why retention rates consistently top 94%. This allows MSCI to raise subscription fees by 3–4% annually with little resistance, a clear demonstration of pricing power.
The Risks
Of course, even MSCI’s Index business is not invincible. Roughly a quarter of Index revenue is linked directly to market values through AUM-based fees. This creates cyclicality when equity markets fall, though recurring subscription base provides a ballast. And MSCI’s largest client, BlackRock, accounts for ~10% of total revenue, creating concentration risk. But this risk is mitigated in the near term by a 10-year licensing deal renewed in 2019 runs through 2029. Lastly, with about two-thirds of revenue generated outside the United States, MSCI also carries exposure to foreign exchange fluctuations. While not a structural weakness, currency swings can create noise in reported results.
Analytics: From Drag to Contributor (~23% of revenue)
The Analytics segment does not carry the same weight as Index, but it has become a dependable supporting business in MSCI’s story. For years, Analytics was seen as a drag on the overall business as high costs, messy integrations, and margins stuck in the low 30s. That has changed. By 2024, Analytics margins nearly doubled to ~49%, turning it into a respectable contributor to the compounder narrative.
Why It Matters
Analytics provides risk and portfolio management tools like Barra and RiskMetrics. These are deeply embedded in institutional workflows and are complementary to Index. If an asset manager benchmarks against MSCI, it makes sense to use MSCI’s tools to measure risk relative to those benchmarks. That tight integration explains why retention rates consistently sit above 93%. This is despite competition from BlackRock’s Aladdin, FactSet, and Bloomberg. The moat here is narrower than the Index segment. It rests on switching costs, not network effects.
Growth Opportunities & Operating Leverage
The demand backdrop is supportive, though. Global markets are becoming more complex, with multi-asset strategies, alternatives, and volatility driving demand for risk tools. MSCI is innovating with AI-driven products like FactorLab and expanding into wealth management.
And so, what really matters is operating leverage. MSCI has already spent heavily to build its platforms. Incremental revenue now flows through at high margins. So even modest revenue growth translates into outsized profitability gains. And like the Index segment, Analytics revenue is largely recurring via subscriptions, adding to MSCI’s predictability.
ESG & Climate: Optionality With Uncertain Durability (~11% of revenue)
ESG and Climate products provide ratings, climate risk data, and compliance tools. In simple terms, if an institution needs to integrate ESG factors or disclose climate risks, MSCI offers the framework.
Growth Drivers
For much of the past decade, ESG was MSCI’s fastest growing segment, growing 20–30% annually. Growth has slowed to about 10% recently, but regulatory drivers remain strong. In Europe, mandatory ESG disclosure keeps demand strong growing >18% YoY in 2024. And MSCI’s scale, which covers 14,800+ companies and 700 climate metrics, is difficult for smaller competitors to match. That coverage creates temporary switching costs and supports retention rates around 92–94%.
Ongoing Investment
Despite headwinds, management continues to invest in this segment. In 2024, MSCI launched GeoSpatial Asset Intelligence in partnership with Google Cloud which covers climate and physical risk across 1.2 million locations tied to 100,000+ companies.
In 2025, MSCI partnered with Swiss Re, bringing in additional climate-risk data. These moves show management’s belief in the long-term potential of ESG integration.
Risks and Competition
The moat here, however, is questionable. ESG lacks universal standards, and competitors like Sustainalytics and S&P offer credible alternatives. U.S. politics are also a headwind as anti-ESG sentiment leads to slower growth and client cancellations. It was this that spooked investors during the Q2 2025 earnings release.
The Optionality
Still, the economics are highly scalable. Once data and models are built, incremental revenues flow through at very high margins (32.1% in 2024). If sentiment or regulation shifts in the U.S., or if global flows into sustainable investing rebound, growth could quickly accelerate. And the investments in new tools suggest MSCI is positioning for that scenario rather than retreating.
Private Assets: Transparency in Opaque Markets (~9% of revenue)
The Private Assets segment provides data and benchmarks for private equity, real estate, infrastructure, and private credit. Built through acquisitions like Burgiss, it targets a massive, but opaque asset class.
The Potential
According to Bain & Co., private AUM could grow from $25 trillion in 2022 to $60 trillion or more by 2032. MSCI has positioned itself with the largest private asset database in the industry, covering $15 trillion in holdings. In 2024 it launched Private Capital Indexes and a private-credit dataset. These tools bring transparency to markets that have long lacked it.
Caveats and Risks
Adjusted EBITDA in this segment has grown at a 60% CAGR over the last five years, but margins remain in the mid-20s. This reflects the high integration costs, operational complexity, and competition from Preqin and PitchBook. Also noteworthy is that private markets themselves are cyclical.
More Optionality
With that said, management’s investment signals conviction. By creating transparency where little exists, MSCI can establish itself as the default standard in private markets. If private credit and private equity continue to expand, MSCI could become indispensable infrastructure. But for now, the business is a long-term bet, not the compounding engine.
Valuation: What the Market Is Pricing In
Taken together, these segments explain the balance inside MSCI. One fortress and three supporting players. That mix is exactly what the market recognizes when it assigns MSCI its premium multiples of ~37x earnings and ~29x EV/EBITDA.
At first glance, those numbers look expensive. But multiples alone do not capture the essence of MSCI’s business. It is capital-light, cash generative, and built on recurring revenues that account for roughly 97% of total revenue. The company routinely converts more than 90% of net income into free cash flow, producing more than $1.4 billion annually. This gives it remarkable capital allocation flexibility and explains why the premium is deserved.
So, the question is less about whether MSCI deserves a premium, and more about whether that premium leaves room for upside. To answer that, it helps to consider DCF scenarios.
📊 The Base Case (~$545/share)
This scenario assumes MSCI keeps doing what it has for a decade. Revenue growth continues in the high single to low double digits. EBITDA margins stay in the 60s. ROIC hovers in the mid to high 20s. The Index business continues to drive 70% of profits supported by recurring fees and AUM-linked revenue growth. Analytics grows steadily in the mid-single digits, and ESG and Private Assets add incremental growth. This is the scenario price into today’s multiples. Durable, predictable compounding, but no surprises.
📈 The Bull Case (~$590/share)
Upside in the name comes if optional segments deliver more than expected. ESG rebounds in the U.S. while sustaining regulatory-driven growth in Europe. Private Assets scale efficiently, riding the expansion of private capital allocations. Analytics leverage AI-driven tools to capture new clients. If these tailwinds play out, revenue growth stays above 10% longer, margins approach 57%, and the ceiling for valuation shifts upward.
📉 The Bear Case (~$460/share)
Downside reflects segment risks materializing. Pressure on ESG persists under U.S. political pressure. Analytics lose ground to Aladdin or FactSet. Private Assets struggle to integrate acquisitions as margins remain sub-25% margins. Given these risks, this scenario calls for SMCI’s revenue growth to slow to ~6% and margins compress toward 54%. Even then, the Index business likely continues to compound, anchoring the business and containing the downside.
Why I Bought the Dip
At today’s price of about $567, MSCI trades slightly above my base-case fair value. That premium reflects the fortress Index economics, while the optionality in ESG, Analytics, and Private Assets creates room for upside if trends improve. Importantly, the bear case highlights that downside is likely capped by the resilience of Index, while the bull case shows that upside rests on whether the optional segments deliver more than expected. In short, the market is paying up for durability while leaving some optionality underpriced.
So, when MSCI’s stock price fell below my base case following Q2 results, I decided to take a position. The pullback was likely due to softness in ESG and Analytics bookings. However, the story remained intact. Firm-wide revenues climbed 9%, Index run rates rose, retention held firm across all segments, and margins stayed above 60%. The pullback reset the price of optionality rather than breaking the narrative.
Final Thoughts
MSCI is not a flawless business. ESG, Climate, and Private Assets are volatile, prone to competition, and carry execution risk. Even Analytics, while stronger, does not offer the inevitability of Index. But that is the point. MSCI does not need every segment to fire perfectly in order to compound. The Index franchise alone anchors growth, fund innovation, and supports capital returns with rare predictability.
That is why MSCI trades at a premium. The fortress ensures durability, while the surrounding businesses give MSCI a chance to compound faster if secular trends play out..
The selloff gave me a chance to buy a high-quality compounder at a fairer price. It was not a call that ESG or Private Assets would suddenly accelerate. It was more about gaining exposure to a compounding machine with optionality intact.
In my portfolio, MSCI also adds something I do not get as much of from core holdings like S&P Global. The company offers broader international exposure that compliments my existing portfolio.
Going forward, I will continue to watch how the optional segments develop. Short of material deterioration in those segments and as long as the core remains intact, I will continue to take advantage of opportunities to build the position.
