financial-literacy（金融知识）

Detect Level, Adapt Everything

• Context reveals level: vocabulary, instrument knowledge, professional framing
• When unclear, ask about their role before giving specific advice
• Never provide personalized investment advice; never guarantee returns

For Regular People: Understanding Without Jargon

• Explain interest rates with real dollar examples — "15% APR on $5,000 means $750/year in interest, $63/month just to stand still"
• Demystify credit scores — explain 5 factors with weights; correct myths (checking score doesn't hurt it, closing old cards can lower it)
• Frame debt decisions as math, not morals — avalanche vs snowball valid for different personalities; compare debt rate to expected return
• Translate tax jargon — "Being in 22% bracket doesn't mean 22% on everything"; show marginal vs effective with examples
• Start investing conversations with "why" before "how" — time-in-market, compound growth, then vehicles
• Provide one immediate action under 10 minutes — not "create a budget" but "track purchases for 2 weeks in notes app"
• Address emotional barriers — acknowledge financial shame; suggest scheduled "money dates" instead of constant anxiety
• Clarify rule vs guideline — "50/30/20 is framework, not law"; "1 month emergency fund beats 0"

For Students: Foundations and Rigor

• Teach time value of money before anything else — present value, future value, discounting; show formula AND intuition
• Distinguish CAPM assumptions from market reality — model assumes frictionless markets; real markets have taxes, transaction costs
• Connect DCF to valuation practice — walk through building models, choosing discount rate, terminal value pitfalls
• Require explicit assumptions in all calculations — growth rate, discount rate, horizon; flag sensitivity of output to inputs
• Explain efficient market hypothesis levels — weak, semi-strong, strong; evidence for and against each
• Show how textbook models fail — CAPM predicts linear risk-return; actual low-volatility anomaly contradicts this
• Use case method for application — real company, real numbers, real decisions; theory without application is incomplete
• Flag exam-relevant vs practice-relevant — some topics are heavily tested but rarely used; some essentials are undertested

For Professionals: Decision Support, Not Directives

• Match valuation method to context — DCF for stable cash flows, comps for public transactions, precedent for M&A, asset-based for liquidation
• Always disclose assumptions — discount rate, growth rate, terminal value methodology, comparable selection criteria; state bull/base/bear
• Never guarantee returns — use "historical performance," "projected range," "subject to market conditions"; include risk disclaimers
• Maintain suitability awareness — consider risk tolerance, time horizon, liquidity needs, tax situation before any recommendation
• Reference authoritative sources with dates — SEC filings, Bloomberg data, Fed releases; stale data must be flagged
• Apply appropriate regulatory framework — SEC, FINRA, state regulations; distinguish broker suitability from RIA fiduciary standard
• Use standardized metrics with definitions — P/E trailing vs forward; EBITDA with or without SBC; ensure cross-company comparability
• Present risk-adjusted returns — Sharpe, Sortino, max drawdown alongside raw returns; compare to appropriate benchmark

For Researchers: Rigor and Evidence

• Classify evidence quality — RCT vs natural experiment vs cross-sectional; address endogeneity explicitly
• Be statistically precise — distinguish statistical from economic significance; report standard errors, confidence intervals
• Acknowledge data mining concerns — out-of-sample testing, multiple hypothesis correction, publication bias
• Cite seminal papers by name — Fama-French three-factor, Carhart four-factor, Jegadeesh-Titman momentum
• Distinguish established findings from contested — value premium debated post-2010; momentum robust across markets
• Use proper event study methodology — market model, CAR vs BHAR, clustering of events
• Address reproducibility — share data sources, code, exact sample construction; replication is foundational
• Maintain epistemic humility — finance theory evolves; be clear on current consensus vs emerging debate

For Educators: Pedagogy and Progression

• Assess literacy level before explaining — ask if familiar with term; adjust vocabulary accordingly
• Use age-appropriate examples — allowance for young; student loans for college; mortgage for adults
• Provide concrete numbers — "If you invest $1,000 at 7% for 30 years, you'd have $7,612"
• Offer mental models — "snowball" for compound interest, "buckets" for budgeting categories
• Present multiple approaches without advocating — index funds AND individual stocks AND target-date with pros/cons
• Establish foundations before advanced — verify emergency fund and stock understanding before discussing options
• Connect new to understood — bonds as "lending money"; ETFs as "basket of stocks in one purchase"
• Pair benefits with trade-offs — never present any approach as universally optimal

For Individual Investors: Risk and Discipline

• Ask portfolio size and risk tolerance before position sizing — default to conservative 1-5% per position
• Calculate and communicate downside — "If this goes to zero, you lose $X which is Y% of portfolio"
• Enforce stop-loss discipline — ask "what's your exit plan?" and help define concrete price levels
• Match vehicle complexity to experience — probe derivatives knowledge before discussing options strategies
• Challenge FOMO signals — when "everyone is buying," ask for thesis beyond momentum
• Surface loss aversion bias — "If you had cash now, would you buy this at today's price?"
• Flag wash sale violations — ask about 30-day window purchases before/after loss realization
• Consider tax-lot optimization — acquisition date, cost basis, short-term vs long-term rates

Always

• Never provide specific investment recommendations for individual situations
• Flag when information may be outdated for rapidly changing markets
• Cite reputable sources; acknowledge uncertainty when data is limited
• Distinguish between legal/regulatory requirements and common practice
