The S&P 500 is at new all-time highs, with the image showing it at 6,754.58 on October 8th, up 0.60% for the day. Despite concerns like AI financing and US debt, money continues to flow into stocks, suggesting underlying strength. Goldman Sachs data indicates money market inflows (risk-free 4% cash) have outpaced stock market inflows YTD, implying significant capital is still on the sidelines and could potentially shift into equities, further fueling the rally.
