Sentiment Indicators & Market Psychology

What is Market Sentiment?

Definition: Overall attitude (bullish/bearish) of investors toward markets.

Importance: Sentiment drives short-term price movements; fundamental value drives long-term.

Sentiment Indicators

VIX (Volatility Index): "Fear gauge"

  • VIX > 30: High fear
  • VIX < 15: Complacency
  • Contrarian use: High VIX = buying opportunity

Put/Call Ratio: Ratio of put options to call options

  • High ratio: Bearish sentiment
  • Low ratio: Bullish sentiment

AAII Sentiment Survey: % of individual investors bullish/bearish

  • Extreme readings (>60% bulls or >40%bears) signal reversals

Fund Flows: Money into/out of equity mutual funds

  • Large inflows: Peak optimism (contrarian sell signal)
  • Large outflows: Peak pessimism (contrarian buy signal)

Using Sentiment Contrarily

Crowd is Wrong at Extremes:

  • Extreme optimism → Overvalued → Sell
  • Extreme pessimism → Undervalued → Buy

Example: March 2020 COVID crash

  • VIX hit 80+ (extreme fear)
  • Contrarian signal: Buy
  • Result: Market +50% in 5 months

Indian Context: During 2021 bull run, record Dem at account openings signaled euphoria → Correction followed.
