KeepRule Use-Case Hub: Behavior-Driven Investing Playbooks

This hub turns common execution stress—panic selling in drawdowns, momentum FOMO, and overtrading loops—into repeatable behavior-first playbooks. Pick the page that matches your trigger, then run its checklist before you touch your portfolio. If you are unsure where to start, choose the playbook that matches your strongest emotion today and commit to one boundary before any order. Each playbook gives a fast diagnosis, 3–7 steps to slow down and re-check evidence, boundaries that stop risk escalation, and a next action via scenarios, principles, and prompts. Use it to improve process—not to get price targets or guaranteed trades.

Situation-specific playbooks for panic selling, FOMO entries, and overtrading—each built around a checklist, boundaries, FAQ, and a concrete next action.

Use Case: Market Crash Anxiety Without Panic Selling

Market crash anxiety is normal when prices gap down and headlines get loud, but the right response is not to guess the bottom or make one dramatic trade. Use this playbook to act in a strict order: protect near-term liquidity first, re-underwrite the thesis second, choose one pre-sized add/hold/reduce action third, and schedule the next review before you check price again. It gives you a fast crash checklist, misuse boundaries, and follow-up rules so a violent session does not turn into forced selling, oversized averaging down, or a permanent behavior mistake.

Use Case: Managing FOMO Before Entering Overheated Stocks

FOMO happens when price action and social proof overwhelm your process. The goal is not to predict the top, but to add a friction layer before execution: thesis-first, downside-first, and a cooling-off window. Use this page to convert urgency into rules so one hot trade cannot hijack your portfolio.

Use Case: Fixing Portfolio Overtrading and Decision Burnout

Portfolio overtrading is rarely about “more information”. It is usually a mismatch between stimulus and process: too many inputs, unclear rules, and no stable review cadence. The result is decision fatigue, inconsistent sizing, and reactive trading that feels busy but not effective. This playbook helps you slow down without freezing: install a trade cap, move decisions into scheduled windows, raise your minimum trade-quality bar, and audit rule violations (not just P&L). The goal is a portfolio you can manage calmly through noise.

FAQ

Who is the use-case hub for?

Investors who already have an investment thesis but struggle with execution under stress—panic selling, FOMO entries, revenge trading, or decision fatigue from too many decisions.

How do I choose the right playbook?

Match the playbook to your trigger, not to your preferred conclusion. Name the stress event (price move/news), your impulse (buy/sell/add), and the timeframe (minutes vs days). Then pick the page whose checklist directly addresses that impulse.

What is the minimum checklist before acting on a use case?

1) Name the trigger and the impulse. 2) Freeze changes for 15 minutes. 3) Run the playbook checklist and pick exactly one next action. 4) Write one boundary that would stop you from escalating risk if you feel worse after acting.

When should I use scenarios vs principles vs prompts?

Use scenarios when you need a guided decision rehearsal under uncertainty. Use principles when you need a stable rule to anchor your behavior across cycles. Use prompts when you want a structured analysis or a written record you can reuse in your journal.

When should I not use a use-case playbook?

If you want a price target, a guaranteed trade, or confirmation that your impulse is “right,” a playbook is the wrong tool. Use it only to set process guardrails and reduce behavior-driven mistakes. ⚠️ Educational only—no financial advice.

How should I measure whether a playbook is working?

Track process signals, not short-term P&L: checklist completion rate, number of impulse trades avoided, time between trigger and action, and whether you respected your written boundary. Improvement usually looks like fewer low-quality trades and calmer decision notes.

Choose the use case matching your current stress pattern, then execute its checklist before taking action.
