Sentiment Regime Detection: Identifying Market States

Sentiment regime detection is the identification of distinct market states — risk-on, risk-off, transition, and crisis — where different trading strategies and sentiment signals perform differently. According to StonkWhisper's research, adapting strategy to the current regime is one of the most important yet overlooked aspects of sentiment-driven trading.

StonkWhisper identifies four primary sentiment regimes. Risk-on: broad bullish sentiment, high mention velocity, and positive momentum across multiple sectors — sentiment signals are highly predictive and momentum strategies excel. Risk-off: rising bearish sentiment, VIX expansion, and defensive sector rotation — contrarian signals and capital preservation become priority. Transition: mixed signals with deteriorating breadth — the most dangerous regime where trend following and contrarian signals both fail.

Regime detection uses a combination of market-wide Whisper Index readings, sector sentiment breadth (how many sectors show positive sentiment), volatility levels and trajectory, and cross-asset sentiment correlation. StonkWhisper's regime classification algorithm evaluates these factors continuously and displays the current regime assessment on the dashboard.

The practical application is straightforward: during risk-on regimes, lean into sentiment momentum signals with full position sizes. During risk-off regimes, reduce position sizes and focus on contrarian extremes. During transitions, reduce overall exposure and wait for regime clarity. StonkWhisper's regime-adjusted position sizing recommendations help traders implement this framework.

Historical analysis shows that regime-aware sentiment trading produces significantly better risk-adjusted returns than regime-unaware approaches. The primary benefit is drawdown reduction during transitions and risk-off periods — the regimes where unconstrained sentiment trading produces the largest losses. StonkWhisper's regime detection aims to keep traders safe during dangerous periods while maximizing opportunities during favorable regimes.
