Reception and transmission of orders on behalf of third parties is defined as receiving a client's order and transmitting it to an authorised provider for execution. For example, an online broker that transmits its clients' share purchase orders to an authorised dealer. This activity is distinct from order execution, where the provider itself concludes the transaction. (Article L.321-1 of the Code monétaire et financier)

Article L.321-1 of the Code monétaire et financier lists the nine distinct investment services, including reception-transmission of orders, order execution, portfolio management, and others. This article is fundamental as it defines the legal framework for provider activities. (As stated in the source material)

Investment advice requires a full suitability assessment evaluating the client's financial situation, objectives, and knowledge. This contrasts with reception-transmission of orders, which only requires an appropriateness test. (Articles L.533-10 to L.533-24 of the CMF)

Non-guaranteed placement operates on a best-efforts basis without any commitment to results, unlike guaranteed placement where the provider commits to a minimum subscription amount. This distinction is crucial as it impacts the provider's liability in the event of a failed issuance. (Article L.321-1 of the CMF)

Services can be classified as services on behalf of third parties (such as reception-transmission of orders) or on own account (such as dealing on own account). Some services, such as investment advice, involve a direct relationship with the client based on personalised recommendations, while others, such as underwriting, concern securities issuance. (Articles L.321-1 et seq. of the CMF)

Portfolio management on behalf of third parties is distinguished by the existence of a management mandate granting the manager discretionary authority to make investment decisions in the client's interest. Without this mandate, the activity would not be considered portfolio management. (Article L.321-1 of the CMF)

Dealing on own account involves the firm committing its own capital, as does a market maker who ensures liquidity of a security by continuously quoting bid and ask prices. This activity differs from services on behalf of third parties as it uses the firm's own funds. (Article L.321-1 of the CMF)

This obligation is set out in Articles D.533-4 to D.533-13 of the CMF. Client categorisation is essential as it determines the level of protection applicable and the specific obligations of the provider towards each client category.
