What it means
Every professionally managed portfolio is measured against a yardstick called a benchmark, usually a published index that represents the market the manager is trying to beat. Active return strips out the part of performance that came simply from being invested in that market and leaves the part attributable to the manager's own decisions.
This matters because market movement dominates most returns. A fund that gained 18% in a year when its index gained 20% actually gave up value even though the headline number looks strong.
Active return makes that gap visible immediately. In practice the figure is calculated over matched periods, monthly, quarterly and annually, then averaged or compounded into a longer record.
Investment committees usually want it reported after fees, because a manager who beats the index by 0.5% while charging 0.8% has left the client worse off than a cheap index tracker would have. A common variant is excess return, which some firms use interchangeably and others reserve for return above the risk-free rate such as short-dated government bills.
Active return is also the top half of the information ratio, where it is divided by active risk to show how much outperformance a manager delivers per unit of deviation from the benchmark. The number is only meaningful if the benchmark is a fair comparison.
A small-company equity fund measured against a large-company index will show flattering active return in some years and dreadful figures in others, which tells you about style differences rather than skill.
In practice
Real-world examples.
Example
A university endowment reviews its global equity manager and finds a portfolio return of 6.8% against a benchmark of 7.5%. The active return is -0.7%, and on a $40,000,000 mandate that is $280,000 of value given up. The committee asks the manager to explain the shortfall before renewing the contract.
Example
A corporate treasurer compares two short-duration bond funds. One returned 4.1% against a 3.9% benchmark and the other returned 4.4% against a 4.5% benchmark. Despite the lower headline number, the first fund produced positive active return and the second did not.
Example
A wealth adviser builds a client report showing five years of annual active return: 1.9%, -0.4%, 2.6%, 0.1% and 1.2%. The pattern shows consistent modest outperformance rather than one lucky year, which supports keeping the manager in place.
Formula
Calculation
Active Return = Portfolio Return - Benchmark Return
A pension fund holds $8,000,000 with an active equity manager. Over twelve months the portfolio returns 11.4% and the benchmark index returns 9.2%.
Active return = 11.4% - 9.2% = 2.2%
In dollars: $8,000,000 x 2.2% = $176,000 of value added above simply buying the index.
The manager charges an annual fee of 0.75%, which costs $8,000,000 x 0.75% = $60,000. Net active return = 2.2% - 0.75% = 1.45%, worth $8,000,000 x 1.45% = $116,000. The client therefore keeps $116,000 of the $176,000 gross outperformance, since $176,000 - $60,000 = $116,000.Case study
Seen in the real world.
The Marlow Ridge Foundation is an illustrative, entirely fictional charitable endowment with $8,000,000 in a single active equity mandate. Its board had been reviewing performance using raw returns only, and after a year in which the portfolio gained 11.4% the trustees were ready to congratulate the manager.
The new finance chair asked for the benchmark figure and found the index had gained 9.2%. That produced an active return of 2.2%, or $176,000, which was genuinely good work. She then deducted the 0.75% management fee of $60,000 and showed the board that the net benefit to the foundation was $116,000.
The board kept the manager but changed its reporting standard permanently. Every quarterly pack now shows portfolio return, benchmark return, gross active return and net active return side by side, so nobody again mistakes a rising market for manager skill.
Watch out
Common mistakes.
- Treating a positive headline return as proof of good management, when the benchmark may have risen further and the active return is actually negative.
- Comparing a portfolio against a benchmark that does not match its investment style, size or geography, which produces active return figures that measure mismatch rather than skill.
- Quoting active return before fees and trading costs, which flatters the manager and overstates what the investor actually received.
Questions
People also ask.
Is active return the same thing as alpha?
They are close but not identical, because alpha adjusts for how much market risk the portfolio took while active return is a straight subtraction of benchmark performance.
Can active return be negative?
Yes, and it frequently is, since a majority of active managers trail their benchmark after fees over long periods.
How much active return should investors expect?
There is no guaranteed level, but most institutional mandates are set with a target of roughly 1% to 3% a year above benchmark, and even that is difficult to sustain.
