The YieldMax Universe Fund of Option Income ETFs (YMAX) closed down 1.3% on December 10th, ending the day at $18.26 amid heightened market volatility and a significant decline in momentum stocks. The broader market experienced a downturn, with the S&P 500 falling 0.6% on December 9th, marking a historic day for momentum stocks, which saw substantial declines. Goldman Sachs' high beta momentum long/short index dropped 6.1%, its worst performance since February 2023, while Morgan Stanley's momentum long index fell 4.4%. This sharp decline in momentum stocks, which have been strong performers throughout the year, contributed to the negative sentiment affecting the market. Additionally, the launch of the YieldMax MARA Option Income Strategy ETF on December 10th may have drawn attention away from existing YieldMax ETFs, including YMAX.
