Value Added Monthly Index (VAMI) is a metric used to measure the performance of an investment portfolio or fund. It tracks the value changes of an initial investment on a monthly basis to show the cumulative returns. VAMI typically starts with a fixed initial amount (e.g., $1000) and adjusts this amount according to the monthly return rates.
