Strategy made a third bitcoin purchase in October last week, bringing monthly spending to $73 million. Strategy bought 267 BTC for slightly more than $22 million, according to a Monday filing. The purchase increased Strategy's holdings to 848,517 bitcoin, worth $69.5 billion at today's prices. The filing also shows that Strategy repurchased $193.1 million of STRC preferred stock. Morgan Stanley Capital International said last week that MSCI was advancing a proposal to exclude non-operating companies from the MSCI Global Investable Market Indexes. The proposal could eventually remove Strategy from the index, leading to fewer institutional investors holding Strategy stock.
