BXMX sells call options against the stocks (or index) it holds, collecting premium income that gets passed through to shareholders as distributions. The strategy generates above-market income in flat or rising markets but caps upside. When the underlying rallies past the strike, the gains above the strike go to the option buyer, not the fund. ### How big is BXMX?

Sustainability depends on (1) whether option premiums stay high enough to cover the announced rate, and (2) whether NAV holds up over time. The NAV Erosion section on this page contrasts total return with price change since inception. If distributions consistently exceed total return, the fund is paying out capital rather than income. ### How much will BXMX's expense ratio cost me over 30 years? On a $10,000 investment compounding at 7% gross return, a 0.89% expense ratio quietly compounds against your balance every year. The Fee Compounding Forecast card above projects the dollar drag for any holding period and assumption you pick. The typical result for a 1.0% expense ratio on a 30-year hold is roughly 25% of the final balance lost to fees. ### How does BXMX charge its expense ratio? The expense ratio is deducted in tiny daily slices from BXMX's net asset value (NAV). You never see a bill. The price quoted on every exchange is already net of fees. There's no "fee day" to avoid; the cost is continuous and built into the trading price. ### Why does BXMX cost more than a fund like VOO? BXMX is an options-income fund (current expense ratio 0.89%).

The Fee Compounding Forecast card above lets you layer in this tax drag alongside the fund fee. Consult a tax advisor. This is not tax advice. ### Are there cheaper alternatives to BXMX?
