Performance reporting for investment advisers is the process of documenting and presenting how a client’s portfolio gained or lost value over a defined period. For advisers registered with the SEC, these reports are not a courtesy. They flow from the fiduciary duty imposed by the Investment Advisers Act of 1940, and the way returns are calculated, labeled, and advertised is now governed by prescriptive rules that took full effect with the SEC’s Marketing Rule in late 2022.
The Legal Basis
Investment advisers owe their clients a fiduciary duty rooted in the Advisers Act. The SEC interprets this as comprising a duty of care and a duty of loyalty, meaning the adviser must put the client’s interests first throughout the relationship.1SEC.gov. Commission Interpretation Regarding Standard of Conduct for Investment Advisers Honest performance reporting is one of the most visible expressions of that duty. If a client cannot see what their money earned, the relationship is hollow.
Section 206 of the Advisers Act makes it unlawful for any adviser to use any device, scheme, or artifice to defraud a client, or to engage in any practice that operates as a fraud or deceit upon a client.2Office of the Law Revision Counsel. 15 US Code 80b-6 – Prohibited Transactions by Investment Advisers Misleading performance figures fall within those prohibitions, and the SEC has brought enforcement actions targeting performance-related violations under the Marketing Rule.3SEC.gov.

For institutional stakeholders such as pension trustees and endowment boards, performance reports are the primary accountability mechanism used to verify that managers are following the mandates in their Investment Policy Statements.
What Goes Into a Performance Report
Every report is built from a small set of inputs, and an error in any of them cascades through the whole calculation.
The beginning market value is the total fair market value of every holding on the first day of the period. It is the baseline against which everything else is measured. From there, the report captures every external cash flow: contributions the investor added and withdrawals they took out, each recorded with exact dates. Even a one-day difference in how a large deposit is dated can shift the reported return, which is why cash-flow handling is where most reporting errors originate in practice.
The remaining inputs are:
- Income earned during the period, meaning dividends, interest, and other distributions from the holdings.
- Asset classification, meaning how holdings are grouped (stocks, bonds, cash equivalents) to show where returns came from.
- The ending market value, meaning the total fair market value of all holdings on the last day of the period.
These figures come from brokerage statements and custodial records. If any of them are wrong or missing, the return figure will be wrong too.
Time-Weighted vs. Money-Weighted Returns
The two dominant calculation methods answer different questions. Time-weighted return (TWR) asks how well the manager performed. Money-weighted return (MWR) asks how well the client’s actual money did.
Time-Weighted Return
TWR measures compound growth by stripping out the effect of external cash flows. Each time the investor adds or withdraws money, TWR treats that as the start of a new sub-period, calculates the return for each sub-period independently, and links them together.4Commonfund. Whats the Difference – Time-Weighted Return vs Internal Rate of Return The result isolates the return attributable to the manager’s investment decisions, regardless of when the client happened to move money in or out.
This is why TWR is the standard for comparing one manager against another. Neither manager controlled their clients’ deposit timing, so TWR keeps the comparison fair. GIPS standards and most institutional investors require it for exactly this reason.
Money-Weighted Return
MWR, sometimes called the internal rate of return, factors in the size and timing of every cash flow, giving more weight to periods when the account balance was larger. If an investor added a large sum right before a strong quarter, MWR will reflect that timing; TWR will not.4Commonfund. Whats the Difference – Time-Weighted Return vs Internal Rate of Return
MWR is the better number when you want to know what actually happened to your wealth. Two clients in the same fund can post very different MWRs if one contributed at a peak and the other at a trough. Neither figure is wrong. The problem is using the wrong one for the context, especially picking whichever method makes a strategy look better in marketing material. That can cross into the deceptive practices Section 206 prohibits.2Office of the Law Revision Counsel. 15 US Code 80b-6 – Prohibited Transactions by Investment Advisers
What the SEC Marketing Rule Requires
The Marketing Rule, at 17 CFR ยง 275.206(4)-1, overhauled how registered advisers can present performance in advertisements. The requirements are far more prescriptive than many advisers initially expected.
Gross and Net Performance Together
Any advertisement showing gross performance (returns before fees) must also show net performance (returns after fees) with at least equal prominence, calculated over the same time period using the same methodology.5U.S. Securities and Exchange Commission. Marketing Compliance – Frequently Asked Questions Gross returns are always higher, and showing them alone paints a misleadingly rosy picture. An adviser cannot bury the net figure in a footnote while splashing the gross number across a pitch deck.
Required Time Periods
When presenting portfolio performance, advisers must include one-, five-, and ten-year returns, each shown with equal prominence and ending no earlier than the most recent calendar year-end.5U.S. Securities and Exchange Commission. Marketing Compliance – Frequently Asked Questions If the portfolio has not existed long enough for one of those periods, the adviser substitutes the portfolio’s entire life. SEC staff has indicated that updating performance for the most recent calendar year-end should generally happen within one month. These requirements make it much harder to cherry-pick a single flattering window and present it as representative.
Extracted and Hypothetical Performance
Extracted performance means the results of a subset of investments pulled from a broader portfolio. If an adviser highlights how their technology stock picks did without showing the full portfolio, that is extracted performance, and it carries additional disclosure obligations. The adviser must either show net performance of the extract or prominently display the total portfolio’s gross and net performance alongside it, with the portfolio figures given at least equal prominence.5U.S. Securities and Exchange Commission. Marketing Compliance – Frequently Asked Questions
SEC staff has also noted that performance extracted from a composite of portfolios may be treated as hypothetical performance, which triggers stricter requirements. Hypothetical results, including backtested strategies, are especially prone to misleading investors because they show what would have happened under ideal conditions rather than what did.
Predecessor Performance
When an adviser wants to advertise returns achieved at a prior firm, the people primarily responsible for those results must now manage accounts at the advertising firm, and the prior accounts must be sufficiently similar to what they manage today. All relevant disclosures must appear clearly and prominently.6U.S. Securities and Exchange Commission. Examinations Focused on the New Investment Adviser Marketing Rule A firm cannot hire a star manager and simply claim their entire prior track record.
GIPS: The Voluntary Standard That Acts Like a Requirement
The Global Investment Performance Standards are maintained by the CFA Institute and govern how firms calculate and present performance. GIPS compliance is not mandated by the SEC, but it has become a practical requirement for firms seeking institutional clients. Most pension funds, endowments, and sovereign wealth funds will not consider hiring a manager that does not claim compliance.
The centerpiece of GIPS is the composite. A composite groups together all portfolios managed to a similar strategy, and the critical rule is that every discretionary, fee-paying account must be included in at least one composite.7CFA Institute. Overview of the Global Investment Performance Standards This prevents firms from showing only their best accounts and hiding the rest. Survivorship bias, where failed accounts quietly disappear from the record, is one of the most common ways performance data gets inflated, and composite rules exist to stop it.
GIPS recommends but does not require independent verification. A verifier examines whether the firm complied with composite construction requirements on a firm-wide basis and whether its policies are designed to produce GIPS-compliant results across cash flows, benchmarks, fees, and error correction.8GIPS Standards. Guidance Statement on Verification A verified claim carries more weight than an unverified one, but even unverified compliance signals a willingness to submit to standardized discipline.
Benchmarks
A return figure in isolation tells you almost nothing. Earning 8% sounds good until you learn the relevant market index returned 15%. Benchmarking is what turns a raw number into an evaluation.
Under the Marketing Rule’s general anti-fraud provisions, failing to disclose how material market conditions affected performance can itself be misleading. If an adviser presents benchmark comparisons, the benchmark must be appropriate for the strategy. If no suitable benchmark exists, the adviser should say so rather than use an ill-fitting one. Common red flags include comparing a bond-heavy portfolio against a stock index during a bull market, or quietly switching benchmarks after the fact to whichever one flatters the results. A credible report names the benchmark upfront, explains why it was chosen, and sticks with it across reporting periods.
Recordkeeping
Registered advisers must maintain detailed records supporting any performance figures they present. Under Rule 204-2, they must keep all account statements reflecting debits, credits, and transactions for each client, along with all worksheets used to calculate any performance or rate of return presented in any communication to any person.9eCFR. Section 275.204-2 Books and Records to Be Maintained by Investment Advisers That covers advertisements, client letters, and informal communications. If an adviser claims predecessor performance, the written records supporting those calculations must also be kept. In practice, if you question a return figure, the adviser should be able to produce the underlying data. If they cannot, that is both a compliance failure and a warning sign.
Delivery and Frequency
Most firms deliver performance reports quarterly, typically within 30 days of the quarter’s close, with annual reports for tax and planning purposes. Digital delivery through encrypted client portals is the default, though some firms still offer paper copies. Stale reports are a problem beyond convenience: they leave investors unable to make timely decisions about rebalancing, tax-loss harvesting, or changing managers. Firms with strong compliance cultures build reporting into their workflow rather than treating it as an afterthought.
How to Read the Report You Receive
A few habits make a real difference in interpreting what lands in your inbox each quarter:
- Check whether the returns are gross or net. Gross figures will always look better. The number that matters to your wealth is net of all fees. If a report only shows gross, ask for net.
- Look at multiple time periods. A single strong quarter can mask years of underperformance. One-, five-, and ten-year figures, or since inception, give a fuller picture.
- Compare against the benchmark. A 10% return means little if the relevant index gained 14%.
- Know which method is in use. TWR reflects the manager’s skill. MWR reflects your personal experience including the timing of your contributions. Both are valid; they answer different questions.
- Read the footnotes about composites. If a firm’s GIPS composite has recently lost accounts, ask whether the departures reflect performance issues or unrelated client needs.
The most expensive mistakes in investment management rarely come from picking the wrong stock. They come from not understanding what the numbers on the page actually mean, and from not asking the follow-up question when something looks off.
