Sentiment Analysis on the CMT Exam
Sentiment indicators measure investor psychology and are used as contrarian signals. They connect directly to behavioral finance concepts and are tested on CMT Level 2 and Level 3.
For the full guide, see the CMT Exam Guide 2026.
Key Sentiment Indicators
Put/Call Ratio
Compares put option volume to call option volume:
- High ratio (>1.0): Excessive bearishness — contrarian bullish
- Low ratio (<0.5): Excessive bullishness — contrarian bearish
- Related to options and technical analysis
- CBOE equity put/call ratio is most commonly tested
VIX (Volatility Index)
The "fear gauge" measures implied volatility of S&P 500 options:
- VIX > 30: High fear — contrarian buy signal
- VIX < 15: Complacency — potential risk
- VIX spike clustering warns of volatility regime shifts
- Mean-reverting nature makes extremes actionable (see mean reversion)
AAII Sentiment Survey
Weekly survey of individual investors (bullish, bearish, neutral):
- Bears > 50%: Contrarian bullish
- Bulls > 60%: Contrarian bearish
- The bull/bear spread is the key metric
Investors Intelligence (II) Survey
Survey of newsletter writers:
- Professional sentiment — wider coverage
- Extreme bullish readings (>60%) signal caution
- Divergence from market breadth amplifies the signal
Less Common Sentiment Measures
| Indicator | Source | Interpretation |
|---|---|---|
| Margin Debt | NYSE | High margin = excessive leverage |
| Short Interest | Exchange data | High short interest = potential squeeze |
| IPO Volume | Market data | High IPO activity = market euphoria |
| Fund Flows | ICI/Morningstar | Retail flows lag — contrarian |
| CNN Fear & Greed | CNN Business | Composite — extreme readings contrarian |
| NAAIM Exposure | NAAIM | Active manager positioning |
Contrarian Analysis Framework
The contrarian principle: extreme sentiment reliably marks turning points.
- Identify extremes — use 2+ standard deviations from mean (statistical analysis)
- Confirm with breadth — sentiment + breadth divergence = strong signal
- Wait for price confirmation — sentiment alone is not a timing tool
- Monitor duration — prolonged extremes eventually reset
Sentiment & Market Cycles
Sentiment follows a predictable pattern through market cycles:
- Bottom: Maximum pessimism (high put/call, high VIX, high bears)
- Early rally: Skepticism / disbelief
- Mid-trend: Gradual optimism
- Late trend: Euphoria, complacency (low VIX)
- Top: Maximum optimism — Dow Theory distribution phase
This mirrors Wyckoff's accumulation/distribution framework.
