Performance benchmarks help investors track performance over which timeframes?

Performance benchmarks are essential tools for investors as they provide a standard against which the performance of an investment can be measured. These benchmarks can be applied over any chosen timeframe, not limited to specific durations like daily, monthly, quarterly, or annually.

The flexibility of performance benchmarks allows investors to assess their investments over the timeframes that are most relevant to their strategies or investment goals. For example, some investors may wish to track performance daily if they are actively trading, while others may focus on quarterly or annual performance to align with broader financial objectives. This adaptability ensures that benchmarks can accommodate different investing styles and strategies, making them versatile tools within an investor's portfolio management framework.

In contrast, the other options suggest limitations that do not reflect the full range of application for performance benchmarks. Therefore, the correct answer acknowledges the broad applicability of benchmarks across any timeframe as needed by the investor.
