Start with the source
Investor.gov separates short-term savings from investing and explains diversification and time horizon. Read the Investor.gov introduction to investing before using this exercise. The source explains the general process; check its date and any product-specific instructions before acting.
Work through the decision
List company-specific risk, market-wide risk, and product fees. Mark which diversification can reduce and which still needs a separate control.
Write down what you know, what remains unknown, and what evidence would change the plan. Use hypothetical figures or a blank template if you are sharing the exercise with someone else.
Check the boundary
This practice note is educational. It does not establish a live market price, a guaranteed outcome, or a personal recommendation. For a real decision, verify current terms and seek qualified advice where appropriate.
