Strategy (MSTR) fell 9.6% Friday in the first full session after MSCI announced on Oct. 15, after U.S. markets closed, that companies primarily holding assets rather than operating a business would lose index eligibility. While the equity sold off, the company’s 848,250 bitcoin (BTC) remain roughly $5 billion above cost, per its latest SEC filing.
Trading activity accelerated as 31.8 million MSTR shares changed hands, a volume that market analysts put at 1.44x the stock’s normal level. The move underscored how index methodology shifts can hit constituents even when underlying asset positions are unchanged.
Why did Strategy (MSTR) drop 9.6% on Friday?
MSCI announced on Oct. 15 that companies mainly holding assets, rather than running an operating business, will lose index eligibility. Friday was the first full day for markets to digest the change, and MSTR fell 9.6% as 31.8 million shares traded, or 1.44x typical volume, reflecting index-linked and discretionary repositioning.
Index eligibility can influence demand from passive and benchmark-constrained investors. The timing—after U.S. markets closed on Oct. 15—meant Friday captured the first complete session of price discovery under the new framework. The selloff concentrated in the equity, not the firm’s bitcoin holdings.

How do Strategy’s bitcoin holdings compare to cost?
The company reported 848,250 BTC as of Oct. 11, acquired for $64 billion at an average of $75,444 per coin. With bitcoin near $81,434 today, that stack sits about $5 billion above cost, highlighting a widening divergence between the firm’s treasury value and the equity’s one-day decline.
The latest SEC filing shows the position size and cost basis, while spot BTC’s quoted level frames the unrealized gain. The Friday downdraft “hit the equity, not the stash,” emphasizing that index methodology shifts can affect share demand independent of on-chain asset valuations or the company’s average purchase price.
What should investors watch next?
Investors will watch how the MSCI eligibility change impacts index membership and related flows, alongside any subsequent trading as funds recalibrate. They will also monitor bitcoin price relative to the company’s $75,444 average cost and $64 billion aggregate purchase price, given the disclosed 848,250 BTC position and the current gain of about $5 billion over cost.
Volume trends—Friday’s 31.8 million shares at 1.44x normal—offer a barometer for further repositioning. Any additional disclosures in SEC filings could refine understanding of treasury strategy and how market structure changes propagate through MSTR’s trading dynamics.
As markets digest the methodology shift, the spread between equity performance and the value of the bitcoin treasury remains the key axis for positioning.
