My brother wants me to open account with Vanguard so he can buy and sell funds. I think he knows a lot about it. But I am responsible for his money. Not him. I called the special needs trust line at the bank the trust is in. They said I'm not going to get someone to tell me yes or no to individual purchases my brother wants to make. That a financial advisor makes the investment plan for the trust themselves. My brother won't want that he wants to pick the investments. Not sure what to do.
