Bank of America flags cash drop to 3.9% as sell signal for stocks

Investors’ cash cushions fell to 3.9% of portfolios in May, down from 4.3% the month before, crossing the 4% threshold that Bank of America (BofA) treats as a market‑wide sell signal [1]. The decline, the biggest monthly drop since February 2024, was driven by a surge of fund managers moving into equities, with half of the surveyed managers now net overweight stocks—the highest equity allocation in four years [1].

BofA strategists argue that such low cash levels signal “bull capitulation” and warn that the rally may soon run out of dry powder. Michael Hartnett, an investment strategist at BofA Securities, wrote that “early June [is] ripe for profit‑taking, bond yields to determine degree of pullback” [2]. The firm’s historical review of 24 similar sell signals since 2011 shows a median four‑week loss of 1% after the signal fires, with the worst case a 29% drop and the best a modest 4% gain [2].

The cash squeeze coincides with other bearish gauges. BofA’s in‑house Bull & Bear Indicator edged closer to its own sell‑signal territory last month, and bond yields have risen sharply—30‑year Treasury yields topped 5.18%, the highest since 2017, while the 10‑year note climbed to 4.687%, its highest since January 2025 [2][5]. Higher yields raise financing costs for consumers and could dampen the momentum that has lifted the S&P 500 above 7,500 for the first time, a rally largely powered by AI‑related optimism and strong performance from semiconductor and “Magnificent Seven” stocks [2].

Despite the bullish price action, fund managers remain broadly optimistic about the global economy. Only about 4% now expect a hard landing, down from 9% a month earlier, and the share believing the economy could continue expanding without interruption rose from 32% to 39% [1]. Yet the combination of dwindling cash reserves, elevated bond yields, and persistent oil price pressures—oil hovering above $110 a barrel—creates a risk that the market’s optimism could reverse sharply.

If cash levels stay below the 4% mark, BofA’s contrarian framework suggests that a pullback may be imminent, putting a premium on monitoring bond yield movements and any shift in fund managers’ equity allocations. The real question is whether investors will heed the warning and trim exposure before a potential drawdown materialises.
