Dotcom Bubble (1995-2000)

Timeline

1995-1997: Displacement (Trigger)

• Netscape IPO (August 1995): More than doubled on first day
• Internet penetration: US 5% → 20%
• Legitimate technological innovation and investment opportunities

1998-Early 1999: Boom (Expansion)

• NASDAQ 100: Sustained +40% annual growth
• Adding ".com" to name alone drove stock prices up ("the .com effect")
• IPO first-day returns averaged +70%

Late 1999-March 2000: Euphoria (Exuberance)

• "Old Economy vs New Economy" binary opposition
• "Clicks vs Bricks" (online is invincible)
• Valuation metrics ignored: "P/E is outdated"

March 10, 2000: Peak (NASDAQ 5,048.62)

March 2000-October 2002: Panic & Crash

• NASDAQ: -78% (5,048 → 1,114)
• Many bankruptcies: Pets.com, Webvan, eToys, etc.

Bubble-O-Meter Score Estimate (March 2000)

Total: 15/16 points (Critical Zone)

Lessons

1. The Magic of the ".com" Suffix Name change alone drove +50%+ stock price gains (e.g., Zapata → Zap.com)

2. IPO Mania Danger First-day returns of +100%+ becoming normal = abnormal demand overheating

3. "Growth Without Profits" Limits Many "Get Big Fast" strategies failed, ignoring cash flow consequences

4. Fed Rate Hikes as Trigger Consecutive rate hikes 1999-2000 → funding cost rise → valuation justification impossible

Crypto Bubble (2017)

Timeline

2016-Early 2017: Displacement & Boom

• Bitcoin: $1,000 → $3,000 (June 2017)
• Emergence of ICO (Initial Coin Offering)
• Rise of altcoins like Ethereum, Ripple

August-November 2017: Accelerating Boom

• Bitcoin: $3,000 → $10,000
• Coinbase app #1 on US App Store
• "Blockchain revolution" narrative spreads

December 2017: Euphoria Peak

• Bitcoin: $10,000 → $19,783 (December 17 peak)
• Taxi drivers preaching crypto (iconic episode from text)
• University lectures producing "instant experts"
• Family gatherings dominated by investment talk

December 18, 2017-December 2018: Crash

• Bitcoin: $19,783 → $3,200 (-84%)
• ICO scams exposed, regulatory crackdown

Bubble-O-Meter Score Estimate (Mid-December 2017)

Total: 16/16 points (Critical Zone - Perfect Score)

Lessons

1. "Most Dangerous Phase: Rapid Rise After Selling" Example from text: Took profit at $8k→$13k → 10 days later approaching $20k → regret and re-entry impulse

2. Leverage Destructive Power 100x leverage = total loss on 5% adverse move, liquidation cascade accelerates crash

3. ICO Scam Proliferation Raised billions with only whitepapers → many absconded

4. Regulatory Risk Underestimation "Impossible to regulate" narrative → collapse when China/Korea closed exchanges

Pandemic Bubble (2020-2021)

Timeline

March-June 2020: Displacement

• COVID-19 panic → historic monetary easing
• Fed asset purchases, zero rates, fiscal support
• "TINA" (There Is No Alternative): No investment alternative to stocks

July 2020-Early 2021: Boom

• NASDAQ 100: +50% (2020 full year)
• Work-from-home/DX stocks lead (Zoom, Peloton, Shopify)
• Robinhood account openings surge, "Stonks" meme culture

Early 2021: Euphoria

• Meme stocks (GME, AMC) wild swings
• SPAC boom (Q1 2021: 298 formations)
• NFT mania (Beeple artwork $69M, "Bored Ape" etc.)
• Crypto resurgence (BTC $64k, "DeFi Summer")

November 2021: Peak (NASDAQ 16,057)

2022: Reversal

• Fed hawkish pivot (inflation response)
• Interest rate rises → growth stock plunge
• NASDAQ: -33% (2022 full year)
• Crypto bubble collapse (Luna, FTX failures)

Bubble-O-Meter Score Estimate (November 2021)

Total: 14/16 points (Critical Zone)

Special Factors

1. Composite Bubble Stocks, crypto, NFTs, SPACs simultaneously erupting, capital swirling

2. Memeification Investment decisions shift from "fundamentals" to "memes" and "community" (GME, DOGE)

3. Zero-Rate Side Effects "Risk-free rate = 0" → illusion that theoretical price of all assets approaches ∞

Lessons

1. End of Monetary Easing = Bubble Collapse Trigger Reversal moment Fed turned hawkish (November 2021)

2. Multi-Asset Simultaneous Bubbles Amplify Danger Correlation approaches 1.0 → diversification benefit vanishes

3. Meme Investment Limits Short-term crowd frenzy unsustainable, fundamental reversion inevitable

Common Patterns

Pattern 1: Trigger Always "Monetary Policy Shift"

Pattern 2: Bubble Stage Time Allocation

Typical Bubble Cycle (total 18-36 months):
Displacement:   20% of duration (tech innovation, policy change)
Boom:           40% of duration (rational expansion)
Euphoria:       30% of duration (exuberance)
Profit Taking:  5% of duration (caution period)
Panic:          5% of duration (crash)

Important: Euphoria occupies 1/3 of total = source of "lasts too long" impression

Pattern 3: Staged Social Penetration Expansion

Phase 1: Experts, early adopters (institutional investors, tech enthusiasts)
    ↓ 1-2 years
Phase 2: Educated class, white-collar workers (doctors, lawyers, salarymen)
    ↓ 6-12 months
Phase 3: General public (taxi drivers, housewives, students)
    ↓ 1-3 months
Peak reached

Lesson: When Phase 3 detected, 1-3 months remaining

Pattern 4: Media Role

Boom Period:

• Cautiously optimistic "expert views"
• Risks also mentioned

Euphoria Period:

• FOMO incitement: "Don't miss out"
• Over-exposure of success stories
• Risk warners labeled "outdated"

Panic Period:

• Flip to pessimism
• "Who's to blame" witch hunt

Pattern 5: Price Patterns

Uptrend:

Stage 1: Gradual rise (+15-25% annual)
Stage 2: Acceleration (+40-60% annual)
Stage 3: Parabolic (100%+ in months)
         ↑ Public entry here

Downtrend:

Stage 1: Correction (-10-15%) → "buying opportunity" perception
Stage 2: Failed bounce, double top forms
Stage 3: Collapse (-50%+) → Panic

Pattern 6: "This Time Is Different" Excuse Patterns

Lesson: When "this time is different" becomes the mantra, historical repetition is near

Application to Practice

Case Study: Ideal Response During 2017 Crypto Bubble

Premise: Purchased Bitcoin in January 2017 at $1k with $1,000

Actual Price Progression:

• June: $3k (+200%)
• August: $5k (+400%)
• November: $10k (+900%)
• December 17: $19.8k (+1,880%, peak)
• December 2018: $3.2k (-84% from peak)

Scenario A: "Perfect Timing" Illusion (Impossible to Execute)

Sell everything at $19.8k = $19,800 profit

Problem: Cannot predict peak in advance, pure luck

Scenario B: Stair-Step Profit-Taking (Executable)

$3k   → Sell 25% = $750 (remaining $2,250 invested)
$5k   → Sell 25% = $1,250 (remaining $1,500 invested)
$10k  → Sell 25% = $2,500 (remaining $750 invested)
$15k  → Sell 25% = $3,750 (position fully closed)

Total Profit: $8,250 vs Peak: 42% (less than half of perfect) But: Reliably executable, psychologically stable

Scenario C: ATR Trailing Stop (Executable + Upside Capture)

• Early December 2017, ATR (20-day) ≈ $1,500
• Using coefficient 1.5: Stop = $10,000 - ($1,500 × 1.5) = $7,750
• December 17 peak $19,800 → Stop updated: $19,800 - $2,250 = $17,550
• Decline starts → Sell all at $17,550

Total Profit: $16,550 (-11% from peak exit) Benefits: Maximum upside capture, early decline exit

Integrated Lessons

1. Abandon "Perfection" Peak selling impossible. Aim for "satisfaction" with stair-step profit-taking

2. Mechanical Rule Superiority ATR trailing eliminates emotion, exits early in bubble collapse

3. Flexibility by Bubble Stage

   • Boom period: Stair-step profit-taking (conservative)
   • Euphoria period: ATR trailing (aggressive)
   • Panic signs: Immediate exit (defensive)

4. Managing Post-Hoc Regret Evaluation criterion: "secure profit capture" not "could have made more"
