Michael Hartnett, BofA's chief investment strategist, issued a sell signal for risk assets.

He cited 'extreme optimism' among investors.

The bank’s Bull & Bear Indicator rose to 9.4. This threshold historically suggests elevated downside risk for equities.

The report noted 89% of MSCI global stock indexes trade above their 50-day and 200-day moving averages. This pushes markets into 'overbought' territory.

Fund flow shifts detailed significant movement. Bond funds attracted $17 billion.

Gold funds saw $6.7 billion in inflows, the largest since October.

Equity funds experienced $15.4 billion in outflows.

Hartnett prefers bonds as a hedge against disinflation. He maintains a bullish stance on international assets, specifically China.
