MSCI Considers Major Rule Overhaul Targeting "Shell" Companies

Index provider MSCI is proposing a significant change to its methodology that could reshape its global benchmarks. The firm has launched a consultation on a new approach to identify "non-operating companies," aiming to ensure index constituents have genuine business operations beyond mere asset holding.

The Two-Step Screening Process

The proposed framework introduces a rigorous two-stage filter for companies.

  • Stage One: Structural Test. Companies first face an assessment of their operating asset structure.
  • Stage Two: Five-Factor Deep Dive. Firms failing the initial test undergo further scrutiny based on five metrics: the ratio of operating assets, expense intensity, operating cash flow, fair value changes, and capital dependence.

A company risks being deemed ineligible if it fails the core structural test and triggers at least four of the five exclusionary factors.

Simulation Flags Potential Removals

A simulation run by MSCI using data as of May 2026 has sent ripples through the market. The test suggests companies like Strategy and Metaplanet, along with uranium investment firm YellowCake, could be removed from the MSCI ACWI IMI index. Others, such as SharpLink, would be placed on a public watchlist.

Strategy's case is particularly notable. With a free-float adjusted market capitalization of $239 billion in the simulation, it is the largest company flagged for potential removal, linking the proposal directly to massive capital flows.

Grace Period and Financial Impact

MSCI plans to implement a grace period for existing constituents. The proposed rules would require a company to fail the new screens for two consecutive annual reporting periods before being removed, providing a buffer for adjustment.

The financial implications, however, could be substantial. Analysts at JPMorgan previously estimated that Strategy's removal from MSCI indexes alone could trigger roughly $28 billion in passive fund outflows, posing a direct challenge to share prices and liquidity.

What's Next: Decision Expected in October

MSCI clarified that the proposal does not trigger immediate index changes. The firm is gathering feedback from market participants until September 30, with the final consultation results expected to be announced by October 16. Investors worldwide are watching closely as this potential rule change could redefine index composition.
