Futures Trim Gains From "Big Progress" In Japan Trade Talks After UnitedHealth Plummets

US equity futures initially surged following positive US-Japan trade talks, but later retreated after UnitedHealth's significant stock drop. UnitedHealth slashed its outlook, citing higher-than-expected Medicare costs. President Trump criticized Federal Reserve Chair Powell, urging lower interest rates. Despite this, major tech stocks like Apple and Microsoft saw premarket gains. TSMC's strong second-quarter forecast boosted investor confidence. European stocks fell, while Asian markets rose, reflecting varied responses to trade uncertainties. Volatility decreased, with the VIX index falling. The dollar strengthened against the yen, and gold prices remained elevated. Oil prices also increased, driven by the US's aim to eliminate Iranian oil exports.
