MicroStrategy Excluded from S&P 500 Index: What It Means
MicroStrategy (MSTR), the tech company led by Executive Chairman Michael Saylor and widely known as the largest corporate Bitcoin holder, was unexpectedly left out of the latest S&P 500 index update. This announcement caused MSTR’s stock to drop nearly 2% in after-hours trading on Friday, sparking disappointment among investors who had anticipated its inclusion.
The S&P Global committee opted instead to include Robinhood Markets, AppLovin, and Emcor Group in the renowned list, fulfilling market expectations for those stocks. The updated index changes will take effect before the market opens on September 22, 2025.
Robinhood, AppLovin, and Emcor Group See Gains
Robinhood’s inclusion announcement triggered a notable 7.5% increase in its share price during extended trading, while AppLovin and Emcor Group also experienced moderate gains. These movements highlight the positive momentum typically associated with S&P 500 index inclusions, as tracked funds and ETFs adjust their holdings to include new constituents.
Why Was MicroStrategy Overlooked?
Despite strong investor optimism and MicroStrategy’s robust market capitalization and liquidity, the S&P committee took a broader view. Jeff Park, CIO at ProCap BTC, provided insights into the decision, stating, “The committee evaluates fundamentals, market positioning, and sector competition—not just metrics or media narratives.”
The volatility tied to MSTR’s heavy Bitcoin exposure may have played a role in its exclusion. While MicroStrategy made headlines for being one of the largest holders of Bitcoin reserves, traditional financial institutions remain wary of the crypto-focused strategy.
Legal and Policy Challenges
Recently, MicroStrategy benefited from the dismissal of a Bitcoin-related class-action lawsuit, which provided some legal relief. However, its executive leadership’s decision to modify issuance policies didn’t appear to shift investor sentiment—or the S&P committee’s stance. For now, the company remains a prime candidate for future index considerations, although its crypto sensitivity means that its stock will likely remain highly reactive to Bitcoin’s market movements.
