A professional individual or firm registered with the SEC or state securities authorities that provides investment advice for a fee.
A Registered Investment Adviser (RIA) is a professional individual or firm that offers personalized financial advice and is registered with either the U.S. Securities and Exchange Commission (SEC) or state securities authorities.

RIAs often use financial models to provide investment advice. One common model is the Modern Portfolio Theory (MPT), which emphasizes diversification to optimize risk and return.
The role of RIAs is crucial in the financial industry, as they provide tailored investment strategies that help individuals and institutions achieve their financial goals. They play a key part in fostering investor trust and maintaining market integrity.
RIAs serve a diverse clientele, including individual investors, retirement plans, charitable organizations, and institutional clients. Their services can range from portfolio management to comprehensive financial planning.
