Should global stock indexes exclude companies that hold significant amounts of alternative treasury assets?
Investor Bill Miller has formally challenged an MSCI proposal that would remove specific companies from its global market indexes based on new quantitative criteria. The MSCI proposal focuses on filtering out firms that rely heavily on non-operating holdings rather than traditional active operations.
Why it matters
The proposed changes could significantly alter the composition of global indexes, potentially impacting passive investment flows for companies labeled as having low operating cash flow. Investors are watching closely to see if MSCI modifies its criteria to account for firms that maintain value through alternative asset structures.
MSCI utilizes a 50% operating asset threshold for the initial test and applies five secondary quantitative screens to measure capital dependence. A company becomes ineligible for inclusion if it triggers four of these five secondary screens over two consecutive annual periods.
The players
Bill Miller
Bill Miller is a prominent investor who has weighed in on the proposed structural changes to MSCI global equity benchmarks.
MSCI
MSCI is a global provider of investment decision support tools and financial market indexes used by institutional investors worldwide.
The details
MSCI simulations conducted in May 2026 identified Strategy, Metaplanet, and Yellow Cake PLC as potential index deletions. Companies placed on a proposed watchlist include Center Laboratories, Lydia Holding, and SharpLink, though removals only occur after failing applicable screens for two consecutive years.
Timeline
May 2026: MSCI ran simulations identifying potential deletions.
September 29, 2026: Bill Miller submitted a formal response to MSCI.
September 30, 2026: The MSCI consultation period officially closed.
October 16, 2026: MSCI is expected to announce a final decision.
November 2026: Proposed index review scheduled for potential implementation.
Market Dynamics
This proposal reflects a broader effort by index providers to codify how unconventional corporate asset structures are handled within global benchmarks. The move follows a pattern set by the previous MSCI plan targeting companies holding large amounts of Bitcoin, which the index provider ultimately abandoned.
Retail and institutional investors tracking these indexes may see forced portfolio reallocations if MSCI finalizes the removal of specific constituents. Shareholders in affected firms could face increased volatility or decreased liquidity as passive funds adjust their holdings to match the revised index composition.
The takeaway
The ongoing dispute highlights the tension between rigid quantitative index criteria and companies with unique business models that fall outside traditional metrics. Investors should monitor the upcoming October decision to determine if their holdings remain eligible for key global benchmarks.
What happens next
MSCI is expected to announce its final decision regarding the proposed index changes by October 16, 2026.
