Save Settings Abstract Brinson attribution can be used to reconcile the differences between time-weighted returns and money-weighted returns. Both methods can be used together to determine the return rate of a given investment.

If a discrepancy between the two is detected, an appropriate reconciliation should be added. A report template can be used for such a reconciliation.

Time-weighted returns TWR and money-weighted returns internal rate of return, or IRR may produce divergent or even conflicting results from time to time. The IRR method weights the investment return against the cash flow inputs and outputs. The TWR method focuses on specific time intervals, compounding them geometrically.

Practically, the IRR method works better for such investments with unpredictable cash flows as private equity. In contrast, the TWR method is more appropriate for benchmark comparisons of liquid investments—for example, bonds and stocks. The time-weighted return on the investment may have a positive sign even though its money-weighted counterpart has a negative sign. The IRR method is not free from drawbacks either.

For instance, it imputes a reinvestment rate equal to the internal rate of return, which is an unlikely occurrence. Moreover, investment managers seldom have discretion over the timing and sizes of cash flows. Using the Brinson attribution model, the author presents a quantitative decomposition of the discrepancy between the two methods. Given the pros and cons of the TWR and IRR methods, it seems reasonable to proclaim both methods an industry standard for estimating rates of return.

Both rates should be presented to investors, accompanied by an obligatory reconciliation. The author argues that presenting the two return measures will not confuse investors if a proper disclosure is made. He also suggests a report template for making such disclosures. The methodology and background the author outlines might prove helpful to these participants. In general, investment performance attribution is a set of techniques that can be used to analyze the difference between portfolio returns and benchmark returns.

As presented by the author, the attribution analysis focuses on two potential sources of portfolio returns selection and allocation of securities , although it may include such other factors as currency.

The Brinson model decomposes the portfolio return into three components: selection, allocation, and the interaction between the two. Therefore, it is difficult to quote particular numbers.

The methodology presented nevertheless allows one to simultaneously zero out the impact of the different weights on the return estimation and isolate both timing- and selection-related effects. The real need can be addressed by understanding the actual reasons for the discrepancy between portfolio and benchmark returns. The author presents a quantitative methodology that enables a concise and coherent analysis of that discrepancy.

The ultimate goal is to help investors pick the best investment managers and measure their effectiveness. Thus, the author makes an important contribution. This paper joins a substantial block of literature and a multilayered discussion on the industry standard for investment return estimation and presentation. This discussion has powered the investment world for many years and offers a voice of common sense in this important matter.

Performance attribution

Reflective of current investment opinions Specified in advance History[ edit ] In , a working group of the Society of Investment Analysts UK published a paper about analysing the performance of investment portfolios. This paper, although never verified, claims to have introduced the key concept in performance attribution, that active performance can be analysed by comparing the returns of different notional portfolios. In particular, if one examines the performance of a portfolio that holds each sector at the active weight, while earning a passive return within each sector, one can measure exactly the amount of value that is added by asset allocation decisions. The paper introduced the key elements of modern performance attribution: notional portfolios, asset allocation, and stock selection. The perhaps fictional paper presents this analytic paradigm as an extension of previously known concepts. Since it was not an academic publication, it did not claim novelty, even though the approach introduced was new and novel. An excerpt from the paper reads: The working group recommend that the notional fund concept be extended to cover the whole fund, i.

Attribution Analysis

Institutional portfolio performance attribution analysis The files here illustrate Brinson performance attribution. Institutional investment portfolios are typically constructed with a strategic asset allocation which prescribes assets classes for investment, policy weights for each asset class and policy benchmarks for each asset class. The portfolio benchmark is simply the sum of the policy weights times the policy benchmark returns, i. Actual portfolios will have performance which varies from benchmark because actual weight of asset classes within the portfolio may vary from policy weights and the actual returns of asset class portfolios may vary from benchmark returns. Allocation effect is the variation in return due to assets held in weights different from policy.
