What does risk mean?
For a beginner, a useful question is: what could happen to this money, and could I cope with that outcome? Prices can fall. You may need to sell at an inconvenient time. Fees can reduce what you keep.

A portfolio is simply the collection of investments you hold. Owning several products does not necessarily mean they hold different underlying investments.
