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

Contrarian Analysis Framework

The contrarian principle: extreme sentiment reliably marks turning points.

  1. Identify extremes — use 2+ standard deviations from mean (statistical analysis)
  2. Confirm with breadth — sentiment + breadth divergence = strong signal
  3. Wait for price confirmation — sentiment alone is not a timing tool
  4. 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.

CMT Exam Application
