How NakedPnL is positioned in the UK relative to FSMA, FCA rules, the Financial Promotion regime, the journalist exemption, and UK GDPR.

By NakedPnL Research·May 7, 2026·12 min read

TL;DR

NakedPnL is not authorised by the Financial Conduct Authority (FCA) and does not provide a personal recommendation under Article 53 RAO.
The platform's posture relies on the journalist exemption in Article 54 RAO read together with PERG 8 and the FCA Handbook.
The Financial Promotion regime under section 21 FSMA is addressed by avoiding inducements to engage in investment activity.
UK GDPR rights — access, rectification, erasure, portability, objection — are honoured for trader and visitor data.
This page is editorial content, not legal advice. The Financial Services and Markets Act and the FCA Handbook are dense; consult an SRA-regulated solicitor for specific questions.

NakedPnL operates a public registry of verified investment performance produced by individual traders who voluntarily connect read-only exchange API keys or sign on-chain wallet attestations. Daily NAV snapshots feed a time-weighted return calculation; results are recorded in an append-only, SHA-256 chained ledger and Merkle-anchored to Bitcoin via OpenTimestamps so that any third party can independently re-verify them.

This page describes how that activity is positioned under UK regulation. It is written for traders, journalists, prospective users, and counsel who want to understand the platform's framing under the Financial Services and Markets Act 2000 (FSMA), the Regulated Activities Order (RAO, S.I. 2001/544), and the FCA Handbook.

How NakedPnL is classified in the United Kingdom

NakedPnL's published activity is the production and distribution of factual performance data. It does not hold any FCA permission, does not appear on the Financial Services Register, and does not carry on any regulated activity within the meaning of section 19 FSMA — the general prohibition.

Article 53 RAO: advising on investments

Article 53 of the Regulated Activities Order regulates the giving of advice to a particular person on the merits of buying, selling, subscribing for, exchanging, redeeming, holding or underwriting a particular investment. The advice must be a personal recommendation to count — generic information that does not direct itself at the recipient's circumstances is outside Article 53.

NakedPnL publishes the same registry data to every reader of a given page. Nothing on the platform is tailored to a specific user's portfolio, objectives, or risk tolerance. The platform does not collect financial-suitability data, does not run a know-your-suitability process, and does not offer model portfolios. On those facts, the content is generic information and not advice within the meaning of Article 53. PERG 8.28 (the FCA's perimeter guidance on the meaning of personal recommendation) describes the line in detail.

Article 54 RAO: the journalist exemption

Article 54 of the RAO excludes advice given in a newspaper, journal, magazine, or other periodical publication, the principal purpose of which is not to give advice of a kind regulated by Article 53 or to lead to a regulated activity. PERG 8.20 to 8.22 of the FCA Handbook elaborate the test, with the Authority looking at the publication's principal purpose, its breadth of editorial content, and whether it is a vehicle for promoting specific dealings.

NakedPnL's principal purpose is the publication of verified, factual performance data. It does not promote dealings in any particular investment, does not solicit subscriptions to any fund, and does not earn commission for routing trades. The Article 54 framing is consistent with the platform design. As with all RAO exclusions, suitability is fact-specific and is ultimately a matter for a court or the FCA.

Section 21 FSMA: the financial-promotion regime

Section 21 FSMA prohibits, in the course of business, communicating an invitation or inducement to engage in investment activity unless the communication is approved by an authorised person, or an exemption applies. The Financial Promotion Order (FPO, S.I. 2005/1529) sets out the exemptions in detail.

NakedPnL does not communicate invitations or inducements to engage in investment activity. Registry pages are presented as factual performance data with explicit disclaimers, the registry is structured as a record of past results rather than a sales channel for products, and the platform earns no fees tied to specific trades or fund subscriptions. Where a trader's profile is shared on social media, the platform is conscious of the FCA's 2024 finalised guidance on financial-promotion approvals (PS24/2) and aims to avoid framing that converts published data into a promotion.

What NakedPnL does not do

No copy trading. The platform cannot replicate one trader's positions into another user's account.
No personal recommendations. The platform does not collect suitability data and does not provide tailored advice.
No broker affiliate links. The platform does not earn commissions for routing users to specific brokers or venues.
No investor-trader matching. The platform does not arrange deals between investors and traders.
No custody. Read-only API keys cannot move funds; wallet attestations are signature-based and do not grant transfer authority.
No execution. The platform never sends orders to any venue.

These design decisions are encoded as feature flags in the codebase, all set to false, and protected by a continuous-integration test that fails the build if any flag is changed.

What UK users should know

UK users should treat the registry as factual performance data and nothing more. Past performance is not a reliable indicator of future results, a phrase the FCA's Conduct of Business Sourcebook (COBS 4.6) requires regulated firms to display when discussing past performance. NakedPnL displays an equivalent statement on every trader profile.

If a third party offers to manage your money on the basis of a NakedPnL track record, you should check whether that third party is on the FCA's Financial Services Register and holds the appropriate permissions. NakedPnL does not vouch for any third-party manager and does not benefit from any such arrangement.

The platform is a data controller for the personal data of UK users under UK GDPR and the Data Protection Act 2018. Lawful bases used include performance of a contract for users who have created an account, legitimate interests for visitor analytics that are minimal and aggregated, and explicit consent for the public listing of a trader's handle and TWR series in the registry.

Data-subject rights — access, rectification, erasure, restriction, portability, and objection — are exercised through the privacy contact. Erasure removes the public-facing registry entry and the associated account, subject to retention obligations imposed by other applicable law. Complaints can be raised with the Information Commissioner's Office (ICO).

Tax considerations

NakedPnL is not a UK financial-services intermediary and does not produce HMRC-facing tax statements for users. Traders remain responsible for reporting gains under the Capital Gains Tax regime or, where applicable, income-tax treatment under HMRC's Cryptoassets Manual (CRYPTO22000 onwards). A chartered tax adviser is the right point of reference for specific questions.

United Kingdom disclaimer variant

The platform applies a UK-specific disclaimer at the surface of the user interface. The disclaimer variant key is uk, configured in lib/jurisdictions.ts, and reads: NakedPnL is not authorised by the Financial Conduct Authority. Information presented is not a personal recommendation under Article 53 RAO. UK users also see a cookie banner because UK PECR (Privacy and Electronic Communications Regulations) requires informed consent before non-essential cookies are set.

Frequently asked questions

Frequently asked questions

Is NakedPnL authorised by the FCA?

No. NakedPnL does not hold a Part 4A permission under FSMA and does not appear on the Financial Services Register. The platform's posture is that its activity falls within Article 54 RAO (the journalist exemption) and outside the scope of Article 53 (advising on investments). That posture is not an FCA determination.

Does the platform make personal recommendations under Article 53 RAO?

No. The platform publishes the same registry data to every reader of a given page, does not collect suitability information, and does not tailor any output to a specific user. PERG 8.28 of the FCA Handbook describes the line between generic information and a personal recommendation; the platform's content is on the generic side.

Is the public display of a trader's TWR series a financial promotion under section 21 FSMA?

The platform's posture is that the registry is factual performance data presented as a record, not as an invitation or inducement to engage in investment activity. Authorised firms or third parties that re-frame the data as a promotion in their own communications are responsible for their own section 21 compliance.

How do I exercise my UK GDPR rights?

Traders can withdraw their public-listing consent from account settings, which removes the registry entry from public endpoints. For broader rights — access, rectification, erasure, portability, objection — contact the privacy team through the channel listed in the privacy notice. Complaints may be referred to the Information Commissioner's Office (ICO).

If a fund manager wants to advertise their NakedPnL track record, can they?

That is a question for the manager and their compliance function. An FCA-authorised firm referencing third-party verified data must satisfy COBS 4 (in particular, fair, clear, and not misleading), Conduct of Business rules on past-performance disclosure (COBS 4.6), and any consumer-duty considerations. NakedPnL does not approve those communications and is not responsible for them.

Does NakedPnL pay HMRC on my behalf or issue any tax statement?

No. NakedPnL is not a UK financial-services intermediary, does not custody assets, and does not have transaction-level data for any user. Traders are responsible for their own tax reporting under HMRC's Cryptoassets Manual or general capital-gains and income-tax rules. A qualified tax adviser is the right resource for specific questions.
