StockTwits is a stock-focused social network with real-time per-ticker opinion — think Twitter for stocks.
1. What it's good for
Search a ticker and a live feed of trader comments appears, with Bullish/Bearish tags — a fast read on reactions to news and overall mood.
2. Useful for momentum trading
Momentum names live on chart and sentiment. StockTwits shows where attention is gathering and how participants feel.
3. Caution
It's individual opinion — hype, doom and coordinated pumping mix in. Use it as a reference and cross-check with financials and charts.
