OVL can be one of the best monthly dividend ETFs of all time because it pays double-digit income without capping S&P 500 upside. It holds VOO as its core and earns income from defined-risk put spreads on the index rather than covered calls; its yield rose from about 3.5% to over 10% as it began paying out more option premium. Since January 2020 it returned 196% versus VOO's 178%. It shines in bull and flat markets but adds complexity and can underperform in severe crashes. x.com x.comÂ
