Capital growth, or indirect return, measures the change in asset's value over a period of time relative to the initial value. The index-level capital growth is calculated as the weighted average using the market value of each constituent.
\text{Capital growth}_{t} = \sum\limits_{i=1}^{n} (w_{i,t-1} \times \frac{V_{i,t,RepCCY}}{V_{i,t-1,RepCCY}} - 1) |
where:
V_{i,t,RepCCY} and
V_{i,t-1,RepCCY} denote constituent i's fair value estimates at times t and t-1 respectively.
w_{i,t-1} denotes the weight of constituent i at time t-1.
