SPY Defensive Pullback Mean Reversion Strategy
Created
Thesis
The Fed's unusually blunt statement and Warsh's hawkish tone have pushed the broad market to multi-month lows, so investors want safer places to sit. Berkshire, whose succession was pre-announced years ago, carries a fortress balance sheet and large cash pile that tends to hold up better when rates rise and stocks wobble. A long-planned, orderly handover to Howard Buffett removes leadership uncertainty rather than creating it. That makes Berkshire a natural defensive long while the market digests more rate hikes.
