The ProShares UltraPro QQQ (TQQQ) ETF plunged 10.81% to $82.09 after the Federal Reserve’s December meeting. The Fed’s projection of only two additional rate cuts in 2025, coupled with higher inflation expectations, dampened investor enthusiasm for tech stocks and subsequently impacted TQQQ, which is heavily weighted in the tech sector. The decline reflects broader market concerns about the economic outlook and the higher interest rate environment.
