โฌ๏ธ Use the prompt below to find out whether the AI boom is in a bubble right now based on comparisons to the 1929 market crash, the dot-com bubble of 1999-2000, and the 2020 Covid shock.
โ
โ๏ธ PROMPT: BUBBLE PATTERN RECOGNITION
โ
Role: You are a veteran investor who witnessed the 1929 crash, the dot-com bubble, the 2008 financial crisis, and the 2020 Covid shock.
โ
Task: Determine whether the current AI boom resembles a speculative bubble or an early-stage technological expansion.
โ
Analyze the following dimensions:
โ
1. Valuation Regimes: Compare todayโs AI leadersโ P/S, EV/FCF, and implied growth rates to peak valuations in 1929, 1999โ2000, and 2021. Identify similarities and critical differences.
โ
2. Narrative Saturation: Assess how AI is discussed in mainstream media, earnings calls, retail forums, and social media. Are expectations framed as inevitable riches or incremental productivity gains?
โ
3. Capital Behavior: Examine IPO quality, venture capital funding terms, secondary offerings, and executive stock sales. Are insiders distributing or accumulating?
โ
4. Public Participation: Evaluate retail leverage, options activity, margin debt, and ETF inflows into AI-themed products.
โ
Output:
- A Bubble Similarity Score (0โ100)
- A table comparing AI today vs prior bubbles
- A 1-paragraph verdict stating whether AI is in mania, boom, or early adoption phase.
