On October 16, Strategy fell 3.05% Overnight to $146.6/share, with turnover of $9.74 million.

The move followed MSCI’s formal adoption of a new rule to exclude non-operating companies from its global investable market indexes, a change that materially increases the risk that Strategy could lose index eligibility next month.

Under the new framework, implementation will occur in the November index review and become effective after November 30, with the final affected list due on November 11. Recent reports said Strategy, because of its bitcoin-heavy balance sheet structure, could face meaningful passive selling if removed; one estimate pointed to roughly $2.8 billion of outflow pressure, while another report cited a substantially larger potential figure. The stock had already weakened in post-market trading after the announcement, underscoring investor concern that index exclusion could pressure valuation even though the rule does not force any sale of the company’s bitcoin holdings.
