Markets were generally quiet, with S&P 500 futures holding at 6,470 after reaching a new all-time high last week. Volatility remained near year-to-date lows as market participants awaited clarity from geopolitical discussions and the upcoming Jackson Hole Economic Symposium. Traders are also looking ahead to Tuesday's housing data and Home Depot earnings, with the week's key events being Wednesday's FOMC minutes and Friday's Jackson Hole testimony from the Fed chair.
