Eaton Vance Tax-Managed Buy-Write Income Fund — Cyborg Score 7/10

Strong
Closed-end buy-write equity funds

Strategic Profile

ETB delivers consistent income through a managed distribution plan with monthly payouts while limiting downside capture through its options overlay strategy. The fund benchmarks against the Cboe S&P 500 BuyWrite Index and appeals to income-focused investors seeking tax-efficient returns in a higher-rate environment.

Cyborg Score Rationale

ETB demonstrates solid income generation with an 8.31% dividend yield as of mid-2026, consistent total investment returns (18.50% NAV return in 2024), and robust assets under management (~$405M in net assets as of end-2024). The buy-write strategy provides downside protection in volatile markets, though returns are capped during significant rallies.
