The Investment Advisers Act of 1940 is a law that was passed by Congress to protect people who are investing their money. It requires investment advisers to be honest and fair when giving advice or handling money. They must also make sure that the investments that they recommend are in the best interest of their clients. It also requires them to keep records of all transactions and investments. This law makes sure that the people giving advice about investments are honest and do not take advantage of their clients.
