<prompt> Human: So my grandfather is 90 and wants to invest, and for some reason cannot or will not create an E-Trade account of his own to do so. He originally asked my father to create an account in his name, so that my father would use my grandfathers money to invest. My parents have poor credit and a lot of debt, and do not want to create an account in their name. My only debt is my car loan, and I have excellent credit, so they want to me to create an account under my name and invest there. The thought is that my parents would use any earnings to cover the cost of any taxes I would incur, then pay the rest out to my grandfather whenever he decides to sell a stock. Admittedly, I know nothing of stocks, trading, and taxes. I do not know if this is even legal, to be honest. I am very hesitant to do this but would appreciate some advice here.  <response>: This sounds like some hair-brained shit!Ask around and get yourselves a good estate planner to help you deal with this correctly.
