Action
Why It Works
Turn off financial news
Removes fear-inducing content
Delete portfolio apps
Prevents obsessive checking
Unfollow finance accounts
Reduces social panic
Avoid market conversations
Limits herd influence
During COVID crash: Investors who did not check portfolios outperformed those who did.

Automation
Benefit
Auto-contributions to 401(k)
Buys more when prices are low
Auto-rebalancing
Removes emotional decisions
Target-date funds
Professional management
Direct deposit to brokerage
Investing before you see cash
When decisions are automated, panic cannot interrupt the process.
Strategy 3: Write an Investment Policy Statement
Create this document before panic strikes:
Section
Content
My investment goal
“Retirement at 65”
My timeline
“30 years”
My risk tolerance
“I accept 40% drops for higher long-term returns”
My strategy
“Hold index funds, never sell in downturns”
When to sell
“Only for rebalancing or retirement withdrawals”
Read this during every market drop. Past you was not panicking.
Strategy 4: Zoom Out
Timeframe
What You See
Daily
Chaos and fear
Monthly
Volatility
Yearly
Cycles
10-year
Growth with dips
30-year
Steady upward line
Every historic crash is a blip on a long-term chart.
Strategy 5: Reframe the Narrative
Panic Thought
Reframe
“I am losing money”
“My shares are on sale”
“It will never recover”
“It has always recovered”
“This time is different”
“They said that every time”
“Smart people are selling”
“The smartest are buying”
“I cannot afford to lose more”
“Selling guarantees the loss”
Strategy 6: Have Cash Reserves
Reserve
Purpose
Emergency fund (3-6 months)
No need to sell investments for bills
Upcoming expenses in savings
House down payment not at risk
Sleep-at-night money
Cash that lets you hold stocks
People with cash reserves panic sell less often.
Strategy 7: Know the Recovery Stats
Drop Size
Average Recovery Time
10-20%
3-6 months
20-30%
1-2 years
30-40%
