What is the pendulum theory and how to judge where we are in the swing?
Marks observed markets swing like a pendulum between extremes:
⬅️ One end: Extreme pessimism (panic, selling, extremely low valuations)
➡️ Other end: Extreme optimism (euphoria, chasing, extremely high valuations)
⏺️ Middle: Reasonable state (but the pendulum spends the least time here)
🔍 Clues for current position:
1. News headline sentiment (all bad news = near pessimistic extreme)
2. IPO market heat (IPO frenzy = near optimistic extreme)
3. Credit standard tightness (easy lending = near optimistic extreme)
4. People around you (taxi drivers discussing stocks = extreme optimism)

Usage Tips
Is the AI's 1-10 rating reliable?
⚠️ The cycle score's value lies in "positioning" not "predicting" — it tells you where the pendulum is, but cannot precisely predict when it will reverse.
The rating's special significance:
- Extreme high/low scores are most informative — the pendulum is more likely to reverse at extreme positions
- Scores in the middle range have lower discriminative power, as the pendulum rarely lingers at the midpoint
- The speed of score change matters more than the absolute value — rapid changes suggest violent sentiment swings
Usage principles:
- The pendulum won't exactly repeat history, but the tendency toward "mean reversion" is eternal
- When the score shows an extreme, don't try to pick the exact bottom — scale in gradually
- AI's cycle assessment is based on historical patterns, but each cycle has unique drivers
