TWR measures the compound rate of growth of an investment by eliminating the impact of cash flows (deposits and withdrawals). It focuses purely on the investment manager’s ability to grow the portfolio. TWR calculations are specifically designed for account-level performance.
Key characteristics of TWR
- Focuses purely on investment selection and portfolio management
- Unaffected by client cash flow timing
- Industry standard for comparing fund managers and strategies
- Ideal for benchmarking against market indices.
How account-level TWR is calculated
TWR calculations for all investments are calculated daily to obtain the most accurate results. The daily figures are then compounded to obtain returns for any required period.
TWR is calculated using the formula below:
(Closing portfolio value – Opening portfolio value – Net Capital Flows) / (Opening portfolio + Net Capital Flows)/2)
Please note:
- TWR calculations are performed based on data available at a specific point in time. Performance figures may not automatically recalculate if updated or revised data becomes available after the initial calculation date.
- TWR figures will smooth out significant spikes or troughs in the daily portfolio balance of an account. Not all days will be included in the final performance figure.
- Due to the current system calculation methodology, TWR figures may not accurately reflect investment performance during periods when in-specie transfers occur.
