Analysis vs management vs consultancy

Brazilian regulation does not treat "giving investment advice" as one thing. It separates distinct regulated activities, each with its own rules and its own registration. Confusing them — or claiming to do one while actually doing another — is a common and serious mistake.

The three activities, simply put

• Analysis (análise de valores mobiliários) — producing reports and recommendations about securities for the public at large. This is the analista, the activity most directly relevant to selling signals and public calls.
• Portfolio management (gestão / administração de carteiras) — actually making investment decisions on someone else’s behalf, managing their money with discretion. A copy-trading "master" who is effectively trading other people’s capital can stray into territory that resembles management — a heavily regulated activity in its own right.
• Consultancy (consultoria de valores mobiliários) — giving personalised, individual advice tailored to a specific client’s situation, without managing the money directly.

Why the boundaries are not academic

The category you fall into determines which registration you need and which duties you owe. Selling a signal feed to the public looks like analysis; running money for followers looks like management; advising one client on their personal portfolio looks like consultancy. Each demands authorisation; doing any of them unregistered carries legal risk.

The honest reading for signal sellers and copy-masters

A great deal of online "signal" and "copy" activity sits uncomfortably close to one or more of these regulated activities while pretending to be mere "education" or "entertainment". That fig-leaf framing does not necessarily protect the provider — and it certainly does not protect you. Again: rules evolve, scope is fact-specific, and you should verify current CVM rules and consult a professional. This is not legal advice.
