Eaton Vance Tax-Managed Buy-Write Opportunities Fund is a closed-end equity fund designed to deliver current income and gains, with a secondary objective of capital appreciation. It invests in a diversified portfolio of U.S. common stocks and systematically writes call options on major U.S. equity indices over a substantial portion of its equity holdings to generate option premium income. The strategy is implemented using internal research and proprietary modeling, with an emphasis on after-tax outcomes to help minimize and defer federal taxes for shareholders. The portfolio is broadly diversified across sectors and typically maintains high equity exposure while overlaying index calls on segments linked to the S&P 500 and NASDAQ-100. The fund pays monthly distributions under a managed distribution plan, reflecting its income-oriented mandate. Co-managed by Eaton Vance and Parametric, it benchmarks performance against both traditional equity and buy-write indices to capture its hybrid equity-income profile. Established in 2005, the fund plays a distinctive role in the market for investors seeking tax-managed equity exposure coupled with systematic option-writing for consistent cash flow.
