The Nuveen Tax-Advantaged Total Return Strategy Fund functions as a diversified, closed-end investment vehicle. Its primary aim is to deliver a substantial after-tax total return, mainly derived from tax-benefited dividend income and growth in capital. The fund predominantly allocates its resources to common and preferred stocks, specifically those whose dividend distributions qualify for reduced income tax rates. To supplement its income and help mitigate fluctuations in net asset value and earnings that might arise from its leveraged structure's sensitivity to interest rate changes, a portion of its holdings is also invested in senior loans. Specifically, at least 60% of its managed assets are committed to common stocks that pay dividends. Furthermore, it allocates between 15% and 25% to senior loans and various other debt instruments, and 5% to 15% to preferred stocks that offer tax-advantaged dividends. Nuveen Fund Advisors, LLC serves as the investment manager for this fund.
