Trading & Sentiment Glossary
The concepts behind Sintinel's signals, explained in plain English — from how sentiment is scored to how positions are sized.
Stock Sentiment Analysis
Stock sentiment analysis measures the collective mood around a ticker from news, social media, and search data to anticipate price moves.
Composite Sentiment Score
A composite sentiment score blends sentiment from multiple sources — Reddit, news, search trends — into one weighted, comparable number.
EV Gap
An EV gap is the divergence between where sentiment points and where price has actually moved — a potential mispricing and trading edge.
Kelly Criterion
The Kelly criterion is a formula for position sizing that maximises long-run growth by betting a fraction proportional to your edge.
Position Sizing
Position sizing is deciding how much capital to allocate to a trade — the discipline that most often separates survivors from blow-ups.
Directional Accuracy
Directional accuracy is the share of signals that correctly predict whether price goes up or down — the honest scorecard for any model.
Paper Trading
Paper trading is simulated trading with fake capital — the safest way to test a strategy or signal before risking real money.
Technical Indicators (RSI, MACD, SMA, EMA)
RSI, MACD, SMA, and EMA are core technical indicators that summarise momentum and trend from price and volume data.
Reddit Stock Sentiment
Reddit stock sentiment tracks the mood of communities like r/wallstreetbets and r/stocks to spot crowd conviction and emerging momentum.
News vs Social Sentiment
News sentiment and social sentiment measure different crowds at different speeds — knowing when to trust each is its own edge.
