E-mini S&P 500 futures rally 1% on risk reversal.

E-mini S&P 500 futures staged a significant reversal on Monday, rallying over 1% to close near the 6630 level. The session began under pressure with prices trading down toward 6583, but risk sentiment improved following headlines suggesting that Middle East talks between the U.S. and Iran were ongoing. This development pushed oil prices lower and provided a boost to risk assets across the board. Equity volatility also saw notable action, marking its highest opening in several months and its widest trading range since April of last year before settling near unchanged. Looking ahead to Tuesday, market participants will monitor the ADP employment change, the Philly Fed non-manufacturing index, and global PMIs, while remaining attentive to geopolitical updates.
