Wall Street adds $1.5 trillion as Dow closes above 53,100 for first time

U.S. equities posted a major risk-on move, adding roughly $1.5T in market value as the Dow closed above 53,100 for the first time. The record close signals strong breadth and investor confidence, likely tightening financial conditions via higher equity valuations and supporting pro-cyclical positioning in the near term. Cross-asset spillovers could lift risk appetite beyond equities, though the direct impact is concentrated in U.S. index exposure.
