E-mini S&P futures slipped back below the 7,550 level to kick off the trading week. Despite a modest overall decline, equity markets face a busy slate of catalysts, including ongoing geopolitical developments in the Middle East with U.S. and Iran negotiations, alongside the fallout from last week's June FOMC meeting where the prospect of sooner-than-expected interest rate hikes caught market attention. With second-quarter corporate earnings just three weeks away and major indices trading precariously close to all-time highs, volatility experienced a modest inverse bid. Looking forward to Tuesday's session, market participants will monitor early ADP employment data, global PMIs, and corporate earnings from FedEx as a bellwether for global commerce.
