For anyone who has/is doing this now: What's the best setup in terms of operation/types of trading accounts if a family member/friend wants me to trade their money for them? Is it as simple as that person opening up a new trading account (or keeping the one they already have), and adding me as "power of attorney"? This is not a big-time operation, and it only involves 1 or 2 people. I'm not planning on starting my own fund and issuing shares, we just want me to have the power to execute trades on behalf of these folks? Would I need any kind of licenses, or have to form my own company first, or can I just execute the trades whenever with no obstacles? Thanks in advance for any replies.
