The Eaton Vance Tax-Managed Buy-Write Income Fund (ETB) is a mutual fund that focuses on generating income for investors through a strategy known as "buy-write." This involves buying stocks and simultaneously selling call options on those stocks, which can provide additional income for the fund. The fund also employs tax-managed strategies to minimize tax liabilities for investors. ETB may be a suitable option for investors looking for a steady stream of income while also managing their tax obligations.
