Strategy Shares Plunge Amid MSCI Index Removal Proposal

Strategy's (MSTR) shares dropped 3.5% in afternoon trading after index provider MSCI proposed removing the company from its Global Investable Market Indexes.

The move is part of a potential rule change affecting non-operating companies with large treasury asset holdings, which includes Strategy due to its massive Bitcoin reserves of roughly 840,400 BTC.

A final decision is expected by October, with changes planned for November 2026, which could force investment funds that track MSCI benchmarks to sell their shares, creating significant selling pressure on the stock.

The company's recent sales of 1,690 BTC, worth around $109 million, below its average cost basis, added to investor worries.
