- Investment Vehicles: Understanding alternatives such as hedge funds or limited partnerships complements your advisory services.
- Portfolio Choices: You might recommend low-cost index funds or dividend stocks based on a client’s risk tolerance and financial goals.
Important Considerations
Passing the Series 66 exam is a critical step, but you must stay current with evolving regulations and ethical standards to maintain compliance and client trust. State requirements can vary, so verify specifics where you plan to register.
Additionally, understanding complex investment structures like a C-corporation or obligations under different security types strengthens your advisory capabilities in diverse market conditions.
