#Definition
Market Sentiment is the prevailing bullish/bearish mood expressed via price levels and trends; can overshoot fundamentals.
#What is Sentiment?
Market sentiment represents the collective emotion and attitude of traders:
- Bullish sentiment: Optimistic, prices rising
- Bearish sentiment: Pessimistic, prices falling
- Neutral sentiment: Uncertain, prices stable
#Sentiment vs Probability
#Important Distinction
- Sentiment: How traders feel
- Probability: Actual likelihood
#Can Diverge
- High sentiment ≠ High probability
- Prices can exceed rational levels
- Emotions drive short-term moves
- Fundamentals win long-term
#Measuring Sentiment
#Price Momentum
- Rising prices: Bullish sentiment
- Falling prices: Bearish sentiment
- Volatility: Uncertainty/fear
#Volume
- High volume up: Strong bullish
- High volume down: Strong bearish
- Low volume: Weak conviction
#Price vs Probability
- Price >> Fair: Overoptimistic
- Price << Fair: Overpessimistic
- Price ≈ Fair: Rational pricing

#Trading Sentiment
#Contrarian Approach
Theory: Trade against extremes
When sentiment is:
- Extremely bullish: Consider selling
- Extremely bearish: Consider buying
- Neutral: Wait for conviction
Rationale: Extremes often overshoot
#Momentum Approach
Theory: Trend is your friend
When sentiment is:
- Bullish: Buy, ride the wave
- Bearish: Sell or avoid
- Changing: Early entry
Rationale: Trends persist
#Which to Use?
- Contrarian: Near resolution, clear data
- Momentum: Early, changing environment
- Hybrid: Use both for different timeframes
#Sentiment Examples
#Example 1: Overoptimism
Market: "Will new product launch on time?"
- Fundamental estimate: 40% chance
- Current price: $0.70 (70%)
- Sentiment: Bullish (hype from CEO tweets)
Analysis: Overpriced due to sentiment
Action: Sell at $0.70, buy at more reasonable level
#Example 2: Panic
Market: "Will GDP exceed 3%?"
- Fundamental estimate: 55% chance
- Current price: $0.30 (30%)
- Sentiment: Bearish (one bad data point)
Analysis: Overreaction to single news
Action: Buy at $0.30, sell when sentiment normalizes
#Causes of Sentiment Shifts
#News Events
- Unexpected announcements
- Expert opinions
- Data releases
- Social media trends
#Herd Behavior
- Following crowd
- Influencer opinions
- Platform trending lists
- FOMO cascades
#Cognitive Biases
- Recency bias: Latest news weighted too heavily
- Confirmation bias: Seeking supporting info
- Anchoring: Stuck on initial view
- Availability: Overweight memorable events
#Sentiment vs Fundamentals
#Short-Term
- Sentiment dominates
- Prices can be irrational
- Emotions drive moves
#Long-Term
- Fundamentals win
- Reality emerges
- Prices converge to truth
#The Trade-off
- Sentiment traders: Profit from moves
- Fundamental traders: Profit from corrections
- Both: Use sentiment for timing, fundamentals for direction
#Managing Sentiment Risk
#Don't Fight Too Hard
- Sentiment can persist
- Being early = being wrong
- Markets can stay irrational
#Position Sizing
- Smaller in sentiment-driven markets
- Larger when fundamentals clear
- Scale in/out gradually
#Time Horizon
- Short-term: Sentiment matters more
- Long-term: Fundamentals matter more
- Match strategy to timeframe
#Practical Tips
#Identify Extremes
- Price far from reasonable range
- Everyone agrees (red flag!)
- Emotional language in discussions
- Volume spikes
#Wait for Mean Reversion
- Extremes don't last
- Prices pull back
- Better entry points emerge
- Patience pays
#Use Limit Orders
- Don't chase sentiment
- Set target prices
- Let market come to you
- Avoid emotional decisions
#Trading Strategy: Contrarian Investing
"Betting against the public" is a classic strategy. When market sentiment reaches extreme levels (e.g., 90% confident in an uncertain outcome), contrarians bet the other way.
- Logic: The crowd is often emotional and overreacts to news.
- Goal: Profit when reality sets in and the price corrects.
