Highlights
- A method for calculating rates of return by compounding interim returns.
- Used in investment performance measurement to ensure accuracy over time.
- Helps investors assess cumulative returns without distortions.
The linking method is a widely used technique for calculating rates of return by sequentially multiplying interim returns over multiple periods. This approach ensures an accurate representation of an investment’s cumulative growth while accounting for variations in performance across different time frames.
Where R₁, R₂, ..., Rₙ represent the interim rates of return for each period. This method prevents misrepresentation of returns by ensuring that each period’s gain or loss is factored into the next.
