S&P 500 futures moved slightly lower to trade around 6,820, giving up ground after reaching all-time highs near 6,900 just two sessions ago. The decline comes amid selling pressure on market leadership following recent earnings and valuation concerns. Additionally, activity is increasing as traders roll positions from December to March ahead of expiration week. Broader markets followed suit, with Dow Jones futures down slightly, Russell 2000 futures falling 0.75%, and the Nasdaq also seeing heavy selling pressure as investors await key labor and inflation data.
