😎 10-Second Show-off Pro Tip for Friends!
😎 Show-off Tip: 'When the CBOE Put/Call Ratio surges above 1.15, extreme retail panic has peaked. Historically, that contrarian fear spike marks exceptional bottom-reversal entries!'
📖 Beginner-Friendly Explanation
STEP 1
Core Concept & Meaning
The Put/Call Ratio (PCR) measures overall market sentiment by dividing total bearish put option trading volume by bullish call option trading volume across major exchanges like the CBOE.
STEP 2
Why It Matters & Mechanism
It functions as one of the most reliable contrarian market indicators used by institutional traders to pinpoint cyclical tops and bottoms.
STEP 3
Practical Investment Tips & Pitfalls
- High PCR (> 1.0 - 1.2, Extreme Fear): Traders are frantically buying protective puts to hedge downside risks. Contrarians view this panic saturation as a prime bottom-fishing signal.
- Low PCR (< 0.6 - 0.7, Extreme Complacency): Call buying overwhelms puts as euphoria takes over. This unhedged complacency typically foreshadows sharp short-term market pullbacks.
- Institutional Hedging Context: Distinguishing between total exchange PCR and retail equity-only PCR provides nuanced clarity on institutional hedging vs retail speculative fever.
📊 Put-call ratio (PCR) calculation formula
Put/Call Ratio (PCR) = Total put option trading volume (Put Volume) ÷ Call option total trading volume (Call Volume)
▶ PCR > 1.0: Downward betting advantage (fear) / PCR < 0.7: Upward betting advantage (greed)
⚖️ Key Comparison at a Glance
| Indicator figures | Market sentiment | Options Market Action | Contrarian Investment Strategy |
|---|---|---|---|
| PCR > 1.1 – 1.3 | Extreme Fear | Buying of put options for downside protection increases | Possibility of short-term bottom formation ↑ Active split purchase |
| PCR 0.8 – 1.0 | Neutral and Balanced | Call option and put option battle | Follow trends and maintain existing positions |
| PCR < 0.6 – 0.7 | Extreme Greed | Buying of rising leveraged call options is concentrated | Beware of short-term highs and increase the proportion of cash |
📌 Practical Market & Real-World Example
During deep stock pullbacks, a spike in the Put/Call ratio to 1.3 often exhausts selling pressure, paving the way for sharp short-covering relief rallies.
