The ProShares UltraPro Short QQQ ETF (SQQQ) closed up 1.09% at $30.64 on December 10th, as the Nasdaq-100 Index (NDX) fell by 0.34% to 21,368.18. The decline in the Nasdaq-100 was driven by a combination of factors, including investor concerns over potential interest rate hikes and ongoing geopolitical tensions that have heightened market volatility. Additionally, the tech-heavy index faced pressure from a sell-off in major technology stocks, which have been underperforming amid fears of slowing growth and regulatory challenges. The market's cautious sentiment was further exacerbated by mixed economic data, which has led to uncertainty about the Federal Reserve's monetary policy direction.
