Yahoo Finance analysis points out that the YieldMax Big 50 Option Income ETF (BIGY) achieved its 12% annual yield target by investing in synthetic long positions and covered call strategies on 50 large-cap U.S. blue-chip companies (such as NVIDIA and Apple). The fund's stock price has risen by 7.44% since December 31, 2025, and by 18.04% over the past year. In contrast, the YieldMax MSTR Option Income Strategy ETF (MSTY), which focuses on a single stock like MicroStrategy, fell by 68.38% over the past year and significantly cut its dividend from $4.42 to $0.22. BIGY's diversified strategy effectively spreads risk, avoiding the significant impact of single-stock volatility.
