Your first 90 days as a DIY investor

List goals and dates, essential monthly expenses, cash reserves, debts and their interest rates, employer benefits, current accounts, and beneficiaries. Locate statements and fee disclosures. Decide which money must remain available and which goals have an investing horizon. If a debt, tax, legal, or benefits question is consequential, verify the rules with an appropriate professional.

Write an initial one-page policy. Learn the account's menu and costs before funding it. Check that the firm is legitimate through independently found official sources, enable strong account security and multifactor authentication, and avoid links in unsolicited messages.

Compare a few understandable, diversified investment approaches that match the goal. Read primary documents, holdings, fees, tax treatment, and the risks covered in this course. Choose a contribution cadence you can sustain and confirm whether the plan invests automatically or merely transfers cash.

If you invest, make sure the amount and any concentration fit your policy. There is no requirement to invest all available money immediately. Test your plan against a downturn in a spreadsheet or in writing, not with essential cash in a live experiment.

Verify contributions and account settings, save records, and compare holdings with the written plan. Make only evidence-based changes. Set the next scheduled review, note one lesson learned, and share your policy or progress with a trusted person if that helps you stay accountable.

A sound first 90 days may include doing nothing in the market while you build the foundation. The milestone is understanding why each decision exists, what could go wrong, and how you will respond—not beating a benchmark in three months.
