According to Bank of America chief strategist Michael Hartnett on July 19, the bank's proprietary bull/bear indicator surged to 9.6, reaching a historic extreme level. Hartnett attributed investor optimism to four core assumptions: no economic hard landing, no Fed rate hikes, no AI capital expenditure cuts, and no Democratic sweep in midterm elections. Latest fund flows validated extreme market euphoria, with U.S. equities recording $55.8 billion in net inflows while money market funds saw a massive $119.6 billion weekly outflow, the largest cash exodus since April 2026; technology stocks accumulated $48.8 billion in three-week inflows, a record high.
Hartnett recommended withdrawing from risk assets and rotating into long-duration Treasury bonds, defensive sectors, high-dividend stocks, and the U.S. dollar. He flagged the Magnificent Seven ETF (MAGS) as a critical indicator: a break below $65 could pressure cyclical sectors broadly, while a break above $70 could signal a re-entry opportunity. The key tail risk involves mega-cap tech firms cutting AI capital spending without driving new highs, potentially triggering sharp losses across growth assets and catalyzing widespread short positions in banks, brokers, and industrials.
