Roundhill S&P 500 Target 20 Managed Distribution ETF offers S&P 500 exposure via long call options with a 20% managed annual distribution. XPAY's simple structure and high payout suit income-focused investors, but long-term reinvestors are likely better off with SPDR S&P 500 ETF Trust. XPAY distributions are primarily return of capital, providing tax deferral benefits similar to or better than SPY's tax efficiency.
