To assess an investment platform, first identify the legal entity and the role it plays in your account; then read the disclosures that apply to that role, add up the costs and incentives, check what any audit actually covered, and test performance figures against their dates, fees, and calculation method. These documents answer different questions: registration records describe a provider, custodian statements record account activity, audits cover specified financial statements or controls, and performance reports present results under stated assumptions.
This guide focuses on U.S. investment advisers and the SEC and Investor.gov materials relevant to them. “Investment platform” is not a single regulatory category: a provider may act as an adviser, broker-dealer, custodian, fund manager, or more than one of these. A disclosure or safeguard that applies to one service does not automatically apply to every account or product the provider offers.
Start with the legal entity and its role
Find the legal name on your account agreement and statements. Then determine which entity provides advice, executes trades, holds assets, or manages any fund you own. One brand can involve multiple legal entities, and the documents and protections relevant to your account depend on the entity, service, and product.
- Identify the account entity. Compare the agreement, account statements, and disclosures. Note any different names for the adviser, broker-dealer, custodian, or fund.
- Identify the service. Establish whether the entity is giving investment advice, executing transactions, holding assets, managing a pooled fund, or performing more than one function.
- Check the provider’s records. For an adviser, use the SEC’s Form ADV information and Investor.gov’s investment adviser guidance to find registration information, filings, and available history or disciplinary records. Registration is not government endorsement or a guarantee of results.
If the service is not an investment-adviser relationship, do not assume the adviser disclosure framework below covers it. Check the documents and regulator records applicable to the specific entity and service.

Know what each document can tell you
| Document | What to look for | What it does not establish by itself |
|---|---|---|
| Form CRS | A short retail-facing summary of services, fees and costs, conflicts, conduct standards, legal or disciplinary history, and questions to ask. | Every detail of the firm’s practices or every term in your account agreement. |
| Form ADV Part 1 | Structured information about the adviser’s business, ownership, clients, practices, affiliations, and disciplinary disclosures. | Whether a particular recommendation or account transaction was suitable or beneficial to you. |
| Form ADV Part 2A brochure | Narrative details about services, fees, conflicts, strategies, risks, and disciplinary matters. | Proof that a described safeguard or conflict-management practice operated as described in a particular instance. |
| Form ADV Part 2B supplement | Information about supervised individuals who provide advice or make discretionary decisions. | A complete account of every person involved in a platform’s services. |
| Account agreement and custodian statements | The parties and terms tied to your account, along with reported holdings, transactions, and balances. | An independent audit of a fund or the platform’s internal controls. |
| Audit report and financial statements | The audited legal entity, period, statements, notes, auditor, and opinion. | A universal certification of account safety, investment quality, or future returns. |
| Performance report or advertisement | Return periods, fee treatment, benchmark, portfolio scope, and whether the results are actual or hypothetical. | A substitute for account records or an audited financial statement. |
For adviser relationships, Investor.gov describes Form CRS as an orientation and Form ADV as a source of more detail. Read the short summary, then consult the relevant filing and agreement for the terms that apply to you. The SEC’s Form ADV brochure bulletin was updated August 27, 2020; it says advisers generally provide clients an annual summary of material brochure changes with a revised brochure or an offer to provide one. Check the latest filing and current SEC rules if the precise delivery obligation matters.
Reconstruct fees and conflicts together
A stated advisory fee is not necessarily the full cost of investing through a platform. Read the brochure’s fee schedule and billing description, then identify other expenses that apply to the account or investments. The brochure may also describe incentives that influence how the firm or its people are paid.

- Advisory charge: Note the rate or schedule, whether it is negotiable, how often it is billed, what balance it is based on, and whether the fee is deducted from your account.
- Other costs: Look for brokerage, custody, transaction, and fund expenses, as well as other charges described in the account or product documents. Compare total costs for the same account type and service level, not just the headline advisory rate.
- Compensation and conflicts: Check for performance-based fees, sales compensation, referral arrangements, payments from product providers, affiliations, or side-by-side management of accounts with different fee incentives.
- How conflicts are addressed: Read what the firm says it does about an incentive and ask how it affects the service or recommendation you receive. Disclosure makes a conflict visible; it does not, by itself, show that the conflict has been eliminated.
The SEC’s Form ADV overview and brochure bulletin describe the kinds of fee, practice, and conflict information advisers disclose. For the specific firm, use its current brochure and applicable agreements rather than assuming every provider has the same fee structure.
Check what an audit covers—and what it leaves out
An audit is meaningful only in relation to its subject and scope. An audit of a pooled fund’s financial statements is not the same as an examination of an adviser’s custody practices, an audit of the platform operator’s internal controls, or a check of your individual brokerage account.

SEC custody materials describe safeguards that can apply when an investment adviser has custody of client assets, including qualified custodians such as banks or registered broker-dealers and, in relevant circumstances, direct periodic statements and an independent surprise examination. Eligible pooled investment vehicles may use an annual audited-financial-statement route subject to conditions, including distributing the statements to investors within 120 days after the fund’s fiscal year end. Which requirements apply depends on the adviser’s custody circumstances, account type, and any applicable exemptions; consult the SEC’s custody-rule compliance guide for the framework.
Read the audit report itself
For any claimed audit, record the legal entity audited, the financial period, the audit firm, the statements and notes included, and the auditor’s opinion. Read any qualifications or emphasis paragraphs rather than relying on a summary in a brochure or marketing material. Check whether investors received the report where distribution is required. A description of an audit process does not establish that a specific period was audited or that its report was delivered: the SEC’s September 17, 2024 enforcement release concerning Nebari Partners, LLC describes charges related to custody-rule audit and distribution failures.

Confirm how required statements were delivered
SEC staff guidance says electronic delivery under the custody rule depends on informed client consent, effective access to the information, and evidence of delivery or access. The guidance is a staff response, not a substitute for the rule text; see the SEC Division of Investment Management’s custody-rule questions and responses.

First identify what the number represents: returns in your account, a pooled fund’s returns, a benchmark comparison, a model, or an advertisement. Do not treat these as interchangeable. A performance presentation is not automatically an account statement or an audited fund financial statement.

For each return figure, record the following before drawing a conclusion:
- Period: The exact start and end dates, and whether the period matches the one used for the comparison.
- Fees: Whether results are gross or net of fees, which fees are included, and any assumptions used to calculate net results.
- Benchmark: The benchmark named, its basis, and whether its strategy and time period make it a fair comparison.
- Portfolio scope: Whether results include all relevant similar portfolios or only selected investments; note extracted results that show a subset.
- Record type: Whether the presentation uses actual, hypothetical, model, or predecessor performance. Ask how a predecessor record relates to the people and strategy now managing the account.
- Cash flows and method: Whether contributions and withdrawals are included and how the return was calculated.
The SEC adviser marketing rule sets conditions and prohibitions involving gross and net performance, time periods, extracted results, hypothetical performance, and predecessor performance. Its effective date was May 4, 2021, and its compliance date was November 4, 2022; those dates describe implementation, not proof that a specific platform complies. The SEC’s marketing-rule guide and staff FAQs explain the requirements and application details.
To reconcile a report with your experience, compare the account’s holdings, transactions, and values with custodian statements, then check the report’s period and calculation method. Past performance cannot predict future results, and an SEC filing or rule is not SEC approval of an investment or of a platform’s return calculation.
Compare providers on matched terms
Use the same account type, service level, time window, and assumptions when comparing providers. Build a side-by-side record using the legal entities and documents you have already identified. Mark information as unknown when it is missing or not comparable rather than filling gaps with assumptions.
| Comparison question | What to match or record |
|---|---|
| Who provides the service? | Legal role, registration, and which entity advises, executes, holds assets, or manages the fund. |
| What will it cost? | Advisory fee plus applicable brokerage, custody, transaction, fund, and other disclosed costs; note billing basis and negotiability. |
| What incentives exist? | Sales compensation, referrals, product-provider payments, performance fees, affiliations, and how each conflict is addressed. |
| How are assets held and reported? | Custodian identity, statement delivery, and which custody safeguards apply to the account or fund. |
| What does the audit establish? | Audited entity, statements, period, auditor, opinion, and whether required reports reached investors. |
| Are performance figures comparable? | Net or gross basis, fees, matching dates, strategy, benchmark, portfolio scope, cash-flow treatment, and actual versus hypothetical or predecessor record. |
Regulator filings and disciplinary records can help assess a provider’s stated practices and history; account statements and underlying fund or performance reports are needed to examine what happened in a particular account or vehicle. Neither source alone establishes future returns or the absence of investment risk.
