Context

Bank of America strategists say the pace of borrowing to buy stocks has cooled from extreme levels earlier in 2026. They note that slowing margin debt growth from such extremes has been associated with previous market peaks, though it does not by itself indicate a decline.

High leverage can amplify downturns, as falling prices trigger collateral demands or forced sales. BofA also pointed to credit spread widening and sector rotation as additional signals, while noting that post-midterm rebounds are historically typical.
