What is the primary use of the 'RR' function on Bloomberg?

The 'RR' function on Bloomberg, which stands for Relative Risk, is primarily designed to analyze the risk of portfolios relative to a benchmark or another portfolio. This function allows users to assess how the risks inherent in different portfolios compare, providing insights into potential performance under various market conditions.

Understanding the relative risk helps investors make informed decisions about asset allocation and risk management by examining metrics such as standard deviation, beta, or value-at-risk in relation to their investment objectives. This is particularly important for portfolio managers who need to balance risk and return to align with their strategies.

The other options, while related to financial analysis, do not correctly define the primary use of the 'RR' function. Revenue reporting, return rates, and bond risk assessments are important considerations in finance but are addressed through different functions on Bloomberg, not the 'RR' function specifically.
