BIG: S&P 500 tops 7,700 for the first time, setting a fresh record high

The S&P 500 breaking above 7,700 marks a fresh record high, reinforcing strong risk appetite and supportive financial conditions. New highs can tighten equity risk premia and improve positioning/flows into broad index exposure, while also increasing sensitivity to macro catalysts that could challenge the rally. The move is most directly relevant to US equities and index-linked volatility and ETF flows in the near term.
