Calculating and Interpreting Time-Weighted Return Effectively

Calculating time-weighted return effectively requires understanding its importance in investment analysis. It's a measure of an investment's performance, taking into account the timing of cash flows.

To calculate time-weighted return, you need to know the investment's beginning and ending values, as well as any cash flows that occurred during the period. This can be done using a time-weighted return calculator or spreadsheet.

Time-weighted return is a more accurate measure of an investment's performance than other metrics, like dollar-weighted return, because it ignores the timing of cash flows.

Time-weighted return is a way to measure the investment performance of a managed fund or portfolio, unique because it removes the distortive impacts of large deposits or withdrawals. This is a crucial aspect, as it ensures that the returns are not artificially inflated or deflated by cash flows.

In contrast to money-weighted rates of return, which include the impacts of cash flows, time-weighted return deliberately excludes them. This means that time-weighted return puts more value on subperiods with higher returns, rather than the size of the cash flows.

Calculating time-weighted return can be a relatively simple process, as illustrated in Example 3. To calculate TWRR, you break a fund's return down into smaller subperiods, with a new period beginning every time money is added to or withdrawn from the fund. You then compute returns for these subperiods by comparing the fund's value at the end of each subperiod with its value at the beginning.

Here's a step-by-step example of how to calculate TWRR:

For instance, in Example 3, the fund's value increased to $1,100,000 by 1 April, and then a new investor contributed an additional $200,000, making the value $1,300,000. By 15 September, the fund's value had increased to $1,450,000, and then a different investor withdrew $100,000, making the value $1,350,000. The fund then had a rocky end to the year, and by 31 December, its value had fallen back to $1,150,000.

Calculating Time-Weighted Return is surprisingly simple, but it's best illustrated with an example. Let's say you want to calculate the TWRR for Fund A over the past year.

Fund A started the year with an investment portfolio valued at $1,000,000. By 1 April, the fund's value had increased to $1,100,000, at which point a new investor contributed an additional $200,000 to the fund's coffers.

You could calculate a simple return using the formula: Return = (Ending value – Beginning value)/(Beginning value). But does this number capture the actual performance of the fund manager? Much of the fund's performance was driven by investors depositing and withdrawing money from the fund.

To get around this and calculate a more accurate rate of return, we can use TWRR. This involves breaking down the fund's return into smaller subperiods, with a new period beginning every time money is added to or withdrawn from the fund.

Here's a step-by-step process to calculate TWRR:

For example, let's calculate the TWRR for Fund A:

$$ \begin{align*}

\text{HPR}_1 & =\cfrac {(53 – 50 + 0.5)}{50} = 7\% \\

\text{HPR}_2 & =\cfrac {(110 – 106 + 1.2)}{106} = 4.9\% \\

\text{Compounded TWRR} & = 1.07 * 1.049 = 12.24\%

\end{align*} $$

$$ \text {Annual TWRR} = (1 + 0.1224)^{0.5} – 1 = 5.9\% $$

The time-weighted rate of return, or TWRR, is a way to measure the investment performance of a managed fund or portfolio. It attempts to remove the distortive impacts that large deposits or withdrawals can have on a fund's returns.

TWRR breaks a fund's return down into smaller subperiods, with a new period beginning every time money is added to or withdrawn from the fund. This helps to accurately capture the fund manager's performance, rather than being influenced by investor cash flows.

The TWRR is typically used when evaluating the performance of an investment manager, as it allows for a fair comparison of different funds. For example, mutual funds and exchange-traded funds are often reported using TWR returns.

A key benefit of TWRR is that it puts more value on subperiods with higher returns, rather than being influenced by the size of the cash flows. This is in contrast to the money-weighted rate of return, which includes the impacts of any cash flows.

To calculate TWRR, you can use the formula: TWRR = (1 + HPR1) × (1 + HPR2) × (1+ HPR3) – 1, where HPRN represents the holding period return for each sub-period.

Here's an example of how to calculate TWRR:

Using this formula, the TWRR for Fund A is 4.5% = (1 + 0.10) × (1 + 0.115) × (1-0.148) – 1.

This return of 4.5% is significantly different from the simple return of 15% calculated earlier, and provides a more accurate representation of the fund manager's actual performance.

Time-weighted return is a way to measure the investment performance of a managed fund or portfolio. It's unique because it attempts to remove the distortive impacts that large deposits or withdrawals can have on a fund's returns.

This is in contrast to money-weighted rates of return, which include the impacts of any cash flows. Money-weighted rates of return are often used by fund managers with greater control over their cash flows, as they put more value on the size of the cash flows.

Time-weighted returns, on the other hand, put more value on subperiods with higher returns. This is why time-weighted returns are typically used when evaluating the performance of an investment manager, such as mutual funds and exchange traded funds.

To illustrate the difference, consider a fund that has outperformed its peers all year, but then a significant investor suddenly decides to cash out their holdings. If you were to calculate the fund's annual return by comparing its value after the withdrawal with its value from 12 months ago, you would be doing the fund manager a disservice.

The time-weighted rate of return can help break down a fund's return into smaller subperiods, with a new period beginning every time money is added to or withdrawn from the fund. This allows for a more accurate assessment of the fund manager's performance.

Here's a comparison of time-weighted return and other metrics:

Time-weighted return is a calculation method that assumes a fixed investment amount, typically $1, and calculates returns based on the passage of time. This method is used to evaluate the performance of investment managers.

In a time-weighted return calculation, any cash deposited or withdrawn is simply ignored for the next period, as if the base investment unit is still $1. This is because the fund manager cannot control when clients are making investments or withdrawals.

Time-weighted returns are typically used when evaluating the performance of mutual funds and exchange traded funds. This is because the fund manager cannot control cash flows, so the calculation focuses on returns as if a fixed amount were invested at each point.

The time-weighted return calculation deliberately excludes the impacts of cash flows, unlike the internal rate of return (IRR) calculation. This means that time-weighted returns put more value on subperiods with higher returns.

Here's a key difference between time-weighted and money-weighted returns:

Time-weighted return is a powerful tool for investors and financial analysts, providing a clear insight into the performance of their investments. It eliminates the impact of external cash flows, making it easier to compare the performance of different investments accurately.

One of the biggest advantages of time-weighted return is that it separates the unadulterated influence of market performance on the portfolio from fundamental returns, which are influenced by cash flows. This allows investors to see which choices made waves versus those that actually aided in growth.

Time-weighted return creates an even playing field, removing cash flow distortions and enabling relevant comparisons. This is especially beneficial for assessing fund managers, selecting investment strategies, or monitoring performance against benchmarks.

Time-weighted return also helps investors to identify underperforming investments in their portfolio, by calculating the rate of return of each investment based on its time-weighted performance. This makes it easier to take appropriate action and adjust the portfolio accordingly.

Here are some key benefits of time-weighted return:

Time-weighted return is a powerful tool for investors and financial analysts, providing a clear insight into the performance of their investments. It enables better portfolio management by providing a clear insight into the performance of an investment portfolio, making it easier to compare the performance of different investments accurately.

The time-weighted return (TWRR) is a great way to measure investment performance, but it's not without its limitations. One major limitation is that calculating TWRR can be incredibly complicated and time-consuming, especially for large funds that process many investments and redemptions daily.

This is because a new holding period begins every time there is a new cash flow, making it a complex process to apply TWRR to real retail funds. In fact, it often requires sophisticated software to perform the return calculation.

The TWRR is sensitive to the amount and timing of cash flows, which can lead to an unfair rating of the fund manager. However, this effect is eliminated by the TWRR, making it a fairer measure of performance.

The TWRR calculation deliberately excludes the impacts of cash flows, unlike the money-weighted rate of return (IRR). This makes IRR a more suitable performance metric for fund managers with greater control over their cash flows.

Here's a comparison of the two:

The TWRR breaks a fund's return down into smaller subperiods, with a new period beginning every time money is added to or withdrawn from the fund. This allows for a more accurate calculation of the fund's return.
