Investment Basics

The costliest beginner mistakes are not bad fund picks - they are investing before the foundation exists, paying 1%+ in fees for decades, concentrating in single stocks or employer stock, and panic-selling in the first real downturn. This skill produces a boring, durable starter plan and a written allocation the user can hold through a crash.

This is general financial education, not personalized investment, tax, or legal advice. Markets carry risk and losses are possible. Account types, contribution limits, and tax rules vary by country - always verify local rules.

Operating procedure

Order matters: readiness gates come before allocation, and allocation comes before any fund discussion, because allocation drives the large majority of a portfolio's risk and return - fund selection is a rounding error next to it.

Step 1: Gather inputs

Collect, with defaults where the user is unsure (label guesses as guesses):

• Emergency fund status (target: 3-6 months of expenses in cash; route to emergency-fund-planner if absent).
• Any debt above roughly 7-8% interest - payoff usually beats expected market returns; anything at 15-25% (credit cards) always does. Route to debt-payoff-planner.
• Employer retirement match available and whether it is being captured.
• Time horizon per goal (retirement, house, education) and honest reaction to a hypothetical 30% portfolio drop.
• Amount available monthly to invest.

Step 2: Apply the readiness gates

Do not proceed to market investing until, in order: (1) any employer match is captured - it is an immediate 50-100% return and beats everything else; (2) high-interest debt (above ~7-8%) is gone; (3) the emergency fund exists. Investing money that may be needed within ~5 years belongs in cash or short-term instruments, not stocks.

Step 3: Set the asset allocation

The stock/bond split is the single decision that matters most. Anchor points:

• "110 minus age" in stocks is a defensible starting heuristic (age 30 → ~80% stocks / 20% bonds); shift 10-20 points more conservative if the user says they would sell in a 30% drop.
• Horizon under 5 years: mostly cash/bonds. 5-15 years: blended. 15+ years: stock-heavy is rational because volatility washes out over long horizons.
• Stocks deliver higher long-term growth with higher short-term volatility; bonds cushion downturns; cash is liquid but loses to inflation; real assets are optional diversifiers, not core.

Write the target percentages down. An allocation that only exists in the user's head gets abandoned at the first crash.

Step 4: Choose vehicles - diversified and cheap

• Core holdings are broad, low-cost index funds spreading risk across hundreds or thousands of companies - never single stocks. A total-market stock fund plus a total bond fund covers most needs; a target-date fund is a legitimate one-fund answer.
• Expense-ratio red lines: broad index funds are widely available under 0.10%; treat anything above 0.50% as needing strong justification, and above 1% as a red flag. A 1% annual fee compounds into losing roughly a quarter of a portfolio's value over 30 years versus a 0.1% fund.
• Cap any single stock - including employer stock - at 5-10% of the portfolio, treated as satellite money the user can afford to lose.

Step 5: Order the accounts for tax efficiency

General priority (verify local equivalents): employer match first, then tax-advantaged retirement accounts up to their limits, then taxable brokerage. Hold tax-inefficient assets (bond interest, high-turnover funds) inside sheltered accounts where rules allow.

Step 6: Automate and pre-commit behavior

Set an automatic monthly transfer on payday (dollar-cost averaging) - investing regularly regardless of headlines removes the timing decision, and time in the market generally beats timing the market. Have the user write one sentence now: "When the market falls 30%, I will do nothing except continue my automatic contributions." Panic selling locks in losses; this sentence is the cheapest insurance available.

Step 7: Rebalance on a rule, not a feeling

Once or twice a year - or when any asset class drifts more than 5 percentage points from target - sell what grew and buy what lagged back to target. This enforces buy-low/sell-high mechanically. Prefer rebalancing with new contributions in taxable accounts to avoid realizing gains.

Worked artifact: starter plan

INVESTMENT STARTER PLAN - [FILL: name], [FILL: age]
Gates:      Match captured: [FILL y/n]  High-interest debt: [FILL none/plan]  Emergency fund: [FILL months]
Allocation: [FILL]% stocks / [FILL]% bonds  (basis: [FILL horizon + risk tolerance])
Vehicles:   [FILL: total-market index fund, ER < 0.10%] / [FILL: total bond fund]
Accounts:   1) employer plan to match  2) [FILL: tax-advantaged account] to limit  3) taxable
Automation: $[FILL]/month on payday, auto-invested
Rebalance:  every [FILL: 6/12] months or at 5-point drift
Crash rule: "When markets fall 30%, I will do nothing except keep contributing."

Bad: "Markets look shaky, so hold cash until things settle, then buy quality stocks like the ones in the news." Good: "80/20 total-market index allocation, $500 automated monthly, rebalance each January, ignore headlines" - no forecast required, every action is a standing rule.

Deliverable

Produce a one-page starter plan containing: the readiness-gate results, a written stock/bond allocation with its rationale, named vehicle types with expense-ratio ceilings, the account priority order with a note to verify local tax rules, the automation amount and date, the rebalancing rule, and the signed crash-behavior sentence.

Do NOT

• Do not discuss fund picks before the allocation is set - allocation drives most of the outcome.
• Do not let a beginner start with single stocks or crypto as core holdings; cap speculative positions at 5-10%.
• Do not skip the readiness gates; investing while carrying 20% credit-card debt is a guaranteed negative-return decision.
• Do not quote country-specific account names or contribution limits as universal facts; flag them for local verification.
• Do not present past returns as promises; use them only to explain why long horizons favor stocks.

Quality bar

• Every gate (match, debt, emergency fund) is explicitly checked, not assumed.
• The allocation is written down with both horizon and risk-tolerance justification.
• Every recommended vehicle type carries an expense-ratio ceiling.
• The plan contains standing rules only - no action requires a market forecast.
• The education disclaimer and local-rules caveat appear in the deliverable.

Escalation

This skill educates; it does not advise. Route to a licensed, fee-only fiduciary advisor for: significant windfalls or concentrated stock positions, equity compensation decisions, cross-border tax situations, or anyone who wants a recommendation on a specific security.
