Time-Weighted Method-GPRS System Technical Lecture

Time-Weighted Method Principle

At time 0, 1, 2...m-1, m, the following data is tracked:

  • Investment Amounts (C1, C2, C3...Cm-1, Cm)
  • Balances (B0, B1, B2...Bm-1, Bm)
  • Rates of Return (j1, j2, j3...jm-1, jm)

The time-weighted method evaluates the performance by considering the changes in balances relative to the investment amounts over time, ignoring the impact of the timing of cash flows.

This approach provides a clearer picture of an investment's performance over a period, isolating it from external cash flows that may distort simple returns calculations.
