QYLD's high monthly income masks a huge long-term opportunity cost versus plain Nasdaq-100 funds.

The Global X NASDAQ 100 Covered Call ETF (QYLD) offers attractive monthly income through selling call options on Nasdaq-100 stocks, but this strategy has significantly limited its share price growth over 12 years. While QYLD returned about 170% with reinvested distributions since 2014, a plain Nasdaq-100 fund like Invesco QQQ gained over 650%, creating a potential opportunity cost of over $480,000 on a $100,000 investment. QYLD's high expense ratio and capped upside due to option selling mean investors trade long-term capital gains for steady income. For those focused on growth rather than income, cheaper alternatives like QQQ or other Nasdaq-100 income ETFs with less aggressive option strategies may be better suited. Investors should weigh income needs against potential long-term wealth loss before choosing QYLD.
