The Investment Advisers Act of 1940 is a key piece of legislation that was created with the aim of providing greater transparency and minimizing conflicts of interest within the investment advisor industry. This act was implemented to protect the interests of investment advisory clients. Its primary purpose is to ensure that advisors provide their clients with the most accurate and equitable advice, and to standardize the actions of those who are responsible for the financial well-being of their clients. By doing so, it has established higher levels of trust and reduced incidences of malpractice within the investment advisory industry.

The Act has proven fundamental in ensuring that all investment advisers operate in a manner that is fair, transparent, and in the best interest of their clients.
