USING STOCK SCREENERS & RESEARCH TOOLS
Plain English
Stock screeners let you filter thousands of stocks down to a shortlist that matches your criteria — like 'P/E under 20, dividend yield over 3%, 52-week high, small cap.' They're one of the most useful tools for finding trade ideas fast.
Going deeper
Stock screeners filter the entire market based on quantitative criteria. Fundamental filters: P/E ratio, P/S ratio, earnings growth, revenue growth, profit margins, debt-to-equity, dividend yield, market cap. Technical filters: price above/below moving averages, RSI levels, new 52-week highs/lows, volume surges, price breakouts. Key screener tools: Finviz (free, powerful), TradingView Screener, Morningstar (fundamental focus), and broker platforms (TD Ameritrade, Fidelity). SEC filings (10-K, 10-Q, 8-K) provide authoritative financial data. Earnings estimates from Zacks, Seeking Alpha, or FactSet show analyst consensus. EDGAR (SEC's database) is free and definitive for regulatory filings.
Examples

Screen parameters: Revenue growth > 20% YoY, EPS growth > 15% YoY, Gross margin > 40%, Market cap $1B-$50B, P/E < 40. This screens for companies growing rapidly but not priced for perfection. Finviz can return this list in seconds from 8,000+ stocks.
Dividend Income Screen
