Strategy shares fall 5% after MSCI index removal, Bitcoin sell-off

The significance here is the double exposure: Strategy is being repriced both by an index-mechanics event and by the underlying Bitcoin move in the same session, which makes it hard to isolate how much of the decline is passive-flow driven versus crypto beta. Index removal matters because it can shift the shareholder base away from benchmark-tracking funds, a structural change rather than a sentiment one. What's worth watching is whether the stock's correlation to Bitcoin tightens further now that one layer of index demand is gone.
