This closed-end equity mutual fund, overseen by Eaton Vance Management, primarily targets U.S. public equity markets. While its core holdings consist of common stocks diversified across various sectors, the fund also employs a sophisticated options strategy for risk management. This involves acquiring short-dated, out-of-the-money S&P 500 index put options and concurrently selling out-of-the-money S&P 500 index call options that share the same term as the purchased put options. The expiration dates for these option positions are strategically staggered across the portfolio. For performance comparison, the fund measures its returns against both the S&P 500 Index and the Barclays U.S. Aggregate Bond Index. Established in the United States on July 31, 2007, the fund is domestically based.
