What considerations are there for making investments on behalf of a friend?
If you want to do #1, then you should form an "investment club." This is an entity that is recognized by the SEC and the IRS.  From the SEC: An investment club is a group of people who pool their money to make investments. Usually, investment clubs are organized as partnerships and, after the members study different investments, the group decides to buy or sell based on a majority vote of the members. Club meetings may be educational and each member may actively participate in investment decisions. https://www.sec.gov/investor/pubs/invclub.htm You should do your own legal research on how to organize, but I believe that a common way is to form a formal partnership, which then provides the legal structure for distributing gains, tax liability, income, and other costs to the members.  IRS publication 550 has a section on Investment Clubs from a tax perspective, but I'd definitely recommend get professional help on this in addition to whatever you can read yourself. As for #2, I believe that's illegal unless you're licensed.
