Strategy Inc (MSTR)

Investing.com -- Strategy Inc stock slid 3.8% in after-hours trading today, hitting a session low of $134.89 before partially recovering to trade at $145.51, as a convergence of Bitcoin price weakness, hotter-than-expected inflation data, and a high-stakes index classification decision due tomorrow weighed heavily on investor sentiment. Bitcoin dropped to approximately $81,000 — its lowest level in roughly a week — after U.S. consumer price index data came in above expectations, reigniting fears that the Federal Reserve will raise interest rates at least once more before year-end, a prospect that historically pressures speculative and crypto-linked assets.

The most acute company-specific pressure stems from MSCI's pending October 16 ruling on whether to classify Strategy as a "non-operating company" under proposed new screening rules, which could result in its removal from the MSCI Global Investable Market Indexes in the November 2026 rebalancing. JPMorgan previously estimated that such an exclusion could put approximately $2.8 billion in passive fund flows at risk, as index-tracking funds would be compelled to liquidate their MSTR holdings. Strategy has formally contested MSCI's proposed methodology, arguing the classification is discriminatory and that index providers should reflect market realities rather than penalize companies for their capital allocation choices.

Adding to the bearish backdrop, Strategy's most recent weekly Bitcoin purchase totaled just 250 BTC for approximately $21.5 million — the slowest accumulation pace of 2026 — raising questions among investors about whether the company's aggressive Bitcoin growth strategy is decelerating. U.S. spot Bitcoin ETFs simultaneously recorded their largest weekly net outflow since June, signaling broader institutional retreat from crypto exposure. The broader U.S. equity market offered little support, with the S&P 500 essentially flat and the Nasdaq modestly negative on the day.

Taken together, the triple headwind of a softening Bitcoin price driven by inflation-fueled rate-hike fears, the imminent MSCI exclusion decision threatening billions in forced selling, and the slowest Bitcoin accumulation of the year created a difficult environment for MSTR shares — leaving the stock more than 52% below its 52-week high of $306.16 and testing the patience of investors who had hoped the company's Bitcoin treasury model would prove resilient against macro crosscurrents.
