The Nuveen Select Tax-Free Income Portfolio 2 functions as a diversified, closed-end investment trust. Its core mission is to deliver consistent income and reliable dividends, which are exempt from standard federal and, when applicable, state income taxes, while simultaneously protecting capital. This objective is primarily achieved by strategically investing in a diverse array of municipal bonds. The fund's holdings are strategically distributed across several sectors, including general and limited tax obligations, healthcare, transportation, consumer staples, and U.S. government-backed securities, among others. Geographically, its investments span numerous states and territories, such as California, Illinois, Texas, New Jersey, Colorado, Washington, Florida, Virginia, New York, Missouri, Iowa, Michigan, Minnesota, and Nevada, alongside other regions. The fund is managed by Nuveen Fund Advisors, LLC, which operates as a subsidiary of Nuveen Investments, Inc. (Nuveen).
