<prompt> Human: So, I should be getting my tax return soon. Im a student, 22 years old, and would like to get into starting an investment portfolio. Im a Finance major and know the book side of investing, but I dont really know much about which companies to do with. Would it be worth it to sign up with TD Ameritrade or other company, insert your opinion here and start trading ETFs for no commission? I could probably pull together about 500 to start my portfolio with. If the odds feel in my favor, I could add money from my emergency fundsavings in the future.I only make about 100week take home pay due to classes, for what that is worth.  <response>: Please read the FAQ and the sidebar links, particularly the Long-Term Investing Start-Up Kit
