The S&P 500 (^GSPC) climbed 0. 88% to 6, 834. 50, the Nasdaq Composite (^IXIC) rose 1. 31% to 23, 307. 62 driven by strength in tech stocks, and the Dow Jones Industrial Average (^DJI) increased 0. 38% to 48, 134. 89, all navigating the volatile trading associated with quad-witching. Market Movers Tech names linked to AI and the broader technology sector led the gains today. Robust performances from Oracle (ORCL +7. 03%) and Micron Technology (MU +6. 89%) supported the market, while consumer stocks fell. Nike (NKE -10. 54%) and Lamb Weston (LW -25. 94%) declined following disappointing earnings and guidance, putting pressure on the retail and consumer staples sectors. Implications for Investors Quadruple witching, occurring four times annually, took place today—the third Friday of December—when stock index futures, stock index options, stock options, and single stock futures all expire simultaneously.
These days typically have high trading volumes and significant volatility, which was evident in today's erratic market movements. This week’s reports indicating easing inflation and a softer labor market have bolstered expectations that the Federal Reserve will cut interest rates early next year. However, Apollo Global Management cautioned that stagflation poses a significant risk in the coming year, particularly if AI technologies fail to deliver anticipated benefits.
