Market Sentiment
Sentiment is the only signal that's deliberately wrong on purpose. Six independent surveys of the crowd's emotion get rolled into one number 0–100, and the rule is the same every time: when the gauge screams euphoria, prepare to sell. When it screams panic, prepare to buy. The crowd is the exit liquidity for the move it just refused to take.
"Be fearful when others are greedy, and greedy when others are fearful." — Warren Buffett
The Composite Gauge — One Number From Six Inputs
CNN's Fear & Greed Index aggregates six market-internal signals into a 0–100 score. It's the headline number on the dashboard, but the value is in unpacking what each input tells you.
Why it works: markets are zero-sum at extremes. When everyone is positioned long (Extreme Greed), there's no one left to buy → only sellers remain → reversal. The reverse holds at Extreme Fear. The composite isn't predicting — it's measuring the size of the imbalance.
The Six Components Behind the Headline
Reading just the headline is shallow. Each component captures a different fear/greed dimension — knowing which is dominant tells you what kind of move is brewing.
1. Stock Price Strength — 52-Week High/Low Ratio
Number of NYSE stocks at 52-week highs vs lows. A handful of mega-caps can mask a weakening tape — this catches that.
- ▸ Many highs >> lows = Greed (bullish breadth)
- ▸ Many lows >> highs = Fear (capitulation signal)
- ▸ Index up but lows > highs = "narrow rally" — index disguises weakness, watch for reversal
2. Stock Price Breadth — McClellan Volume Summation Index
Cumulative difference between advancing and declining VOLUME (not just count). Captures how much capital is moving with the trend.
- ▸ Rising index = volume in winners > volume in losers — strong tape
- ▸ Falling index = bearish accumulation; even neutral price action hides distribution
- ▸ Bearish divergence (price up, breadth down) = late-stage rally warning
3. Put/Call Ratio — Options Hedging Demand
Ratio of put volume (bearish bets) to call volume (bullish bets). Pure measure of how nervous traders are RIGHT NOW.
- ▸ Ratio > 1.0 = more puts than calls — Fear, often bearish-extreme contrarian buy
- ▸ Ratio < 0.7 = call-heavy — Greed, complacency warning
- ▸ Inverse logic: high P/C usually marks panic bottoms; low P/C marks tops
4. Junk Bond Demand — High-Yield Spread vs Treasuries
Risk appetite proxy. Spread between high-yield ("junk") corporate bond yields and safe Treasury yields. Narrower spread = investors reaching for yield = risk-on.
- ▸ Narrow spread = chasing yield = Greed (risk-on environment)
- ▸ Wide spread = flight to quality = Fear (credit stress emerging)
- ▸ Spread blowout often leads equity selloff by weeks — credit market gives early warning
5. Safe Haven Demand — 20-Day Bond vs Stock Returns
Difference in 20-day returns between Treasuries and stocks. When bonds outperform stocks short-term → defensive rotation = Fear.
- ▸ Stocks >> bonds (20d) = risk-on rally = Greed
- ▸ Bonds >> stocks (20d) = defensive rotation = Fear
- ▸ Watch the crossover — flip from one regime to the other often marks turning points
6. Market Volatility — VIX vs 50-Day Average
VIX = implied 30-day volatility on S&P 500 options. Compared to its 50-day moving average. The "fear gauge" everyone references.
- ▸ VIX < 15 = complacency, low hedging — Greed
- ▸ VIX 15–25 = normal regime
- ▸ VIX > 30 = active panic, hedging surge — Fear
- ▸ VIX spike + reversal candle in 30+ zone = capitulation; one of the strongest contrarian signals available
Per-Asset Sentiment — Retail Long/Short %
Beyond the macro composite, you also need symbol-specific retail positioning — what % of retail traders are long vs short on a given pair / asset right now. Different game, different rules.
Where The Number Comes From Matters
Per-asset retail % can come from real broker order books (FX) or be derived from price/volume (everything else).
- ▸ Real broker books = actual client positions — high signal quality
- ▸ Derived / synthetic = inferred from VP and price action — noisier, treat with discount
- ▸ Always check the source label before sizing a trade off this number
Retail Crowding Logic
- ▸≥ 75% long = retail crowded long → fade signal
- ▸≥ 75% short = retail crowded short → fade signal
- ▸50–60% = balanced → no contrarian edge
- ▸Sudden flip while price spikes into a stop cluster = orchestrated stop-hunt likely
Watch for divergence: macro composite says "Greed" while per-asset retail is 80% short on a specific FX pair → that pair is unlikely to follow the broader risk-on tape. Macro and asset-level sentiment can disagree, and when they do, the asset-specific signal usually wins for that instrument.
Contrarian Logic — Why Inverse Reading Works
Sentiment is the only indicator most traders read backwards on purpose. Understanding why prevents misuse.
Mechanic 1: Position Saturation
When 85% of retail is long EUR/USD, it means most marginal buyers have already bought. There's no fuel left for upside — only stops to be taken below current price. The crowded position has nowhere to go but down.
Mechanic 2: Liquidity Targets
Algorithmic books LITERALLY look at retail clustering data. When 80% are long with stops at the same price level, those stops become a liquidity pool — institutions sweep them on purpose. Crowded positioning = stop-hunt magnet.
Mechanic 3: Emotional Symmetry
Extreme fear = panic selling at any price = price overshoots fair value to the downside = mean reversion. Extreme greed = FOMO buying at any price = overshoot to upside = correction. Sentiment quantifies the overshoot.
When contrarian fails: in genuine regime change (war, currency collapse, rate panic), Extreme Fear can persist for weeks while price keeps falling. Contrarian works on REVERSIONS, not on directional shifts in the underlying. Always check if the move is structural (Wyckoff Phase E breakdown) or emotional (overshoot).
Sentiment = Wyckoff Crowd Psychology Quantified
Wyckoff's framework rests on one premise: the public is wrong at extremes, smart money exploits that. Sentiment composites are the modern measurement of that exact premise.
| Wyckoff Phase | Composite Sentiment Signature | Per-Asset Signature | Confluence Read |
|---|---|---|---|
| Phase A (SC) | F&G < 15, VIX spike, P/C > 1.2 | Retail 80%+ short / panic | Capitulation confirmed — A+ contrarian long |
| Phase B (TR) | Drifting toward neutral, slow VIX decay | Retail confused, oscillating long/short | Background sentiment heals quietly during accumulation |
| Spring (Phase C) | Brief F&G dip back to Fear | Retail flips to short on stop-hunt | Crowd takes the bait — strongest entry confluence |
| Phase D (LPS) | Rising back through neutral | Retail starts unwinding shorts | Trend confirmation — momentum traders late-join |
| Phase E (markup) | F&G drifts to 70s, VIX low | Retail piles in long | Late-cycle euphoria — trim, don't add |
| UTAD / Top | F&G > 85, P/C < 0.7 | Retail 80%+ long | Mirror image of capitulation — A+ contrarian short |
Reading principle: Wyckoff phase + sentiment match = thesis confirmed. Wyckoff phase WITHOUT sentiment match (e.g., apparent Phase A but composite still Greed) = fake bottom warning. The crowd hasn't capitulated yet — the move has more downside.
Failure Modes — Where Sentiment Lies
Sentiment is bias, not timing. These are the documented blind spots.
Crisis Persistence
Extreme Fear can sit at < 15 for weeks during real crises (2008, March 2020, regional bank failures).
- ▸ Contrarian buy at first dip can crater another 30%
- ▸ Need confirmation: stabilising VIX + base-building Wyckoff Phase A
- ▸ Don't catch falling knives just because the gauge is red
Macro vs Asset Disagreement
Composite F&G is US equity-flavoured. Doesn't always map to FX or crypto.
- ▸ "Extreme Greed" composite can coincide with crashing JPY (different driver)
- ▸ Always consult per-asset sentiment for the instrument you trade
- ▸ Macro sentiment is regime context, not entry signal
Direct vs Derived Data
A retail % derived from price/volume is not the same as a real broker positioning report.
- ▸ Direct broker data = actual client positions, high signal
- ▸ Derived gauges = inferred from price action, noisier
- ▸ Always discount derived readings vs direct ones
Sentiment ≠ Imminent Reversal
F&G can hold > 80 for entire bull runs that last quarters.
- ▸ "Extreme Greed" alone is not a sell trigger
- ▸ Need divergence: price up + breadth declining + VIX rising
- ▸ Use as filter ("don't add" / "trim") not standalone entry
Operational Cheatsheet
Daily routine when reading the sentiment widget.
| Read | Confirm With | Action |
|---|---|---|
| F&G < 15 + VIX > 30 | Wyckoff Phase A signs (selling climax) on HTF | Premium contrarian long bias — wait for Spring |
| F&G > 85 + VIX < 13 | Wyckoff Phase E or topping pattern | Premium contrarian short bias — wait for UTAD |
| Per-asset retail ≥ 75% one side | Direct broker data (not derived) | Fade the crowd — entry at structural level |
| Liquidity Grab Alert | Sudden retail flip + price spike | Stop-hunt detected — trade with smart money direction |
| Bearish breadth divergence | Index up + Stock Strength flat / down | Late-cycle warning — trim longs, don't short yet |
| Junk bond spread blowout | Credit stress visible before equity drop | Risk-off coming — reduce position size |
| F&G ≈ 50, VIX 15–20 | Neutral regime, no extremes | No sentiment edge — defer to Wyckoff / Pattern |
| Only derived (not direct) gauge available | No direct broker positioning data for this pair | Discount the reading — confirm from another source |
Closing principle: sentiment tells you the SIZE of the imbalance, not the timing of the resolution. A capitulation read at the wrong Wyckoff phase is just a deeper capitulation. Pair sentiment with structure for entries — never alone.
