Understanding Stock Market Industries

The Global Industry Classification Standard (GICS) subdivides the stock market into sectors and industries, giving investors a structured way to compare companies that share similar business models, revenue drivers, and competitive dynamics. While sectors provide a macro-level view of the economy, industries offer the granular lens needed for peer analysis and targeted stock picking.

Stock Expert AI currently tracks 50 industries spanning 28,662 publicly traded stocks across all 11 GICS sectors. The largest industry by company count is Asset Management with 8,332 stocks, while the most specialized is Leisure with 142 stocks.

Each industry page on Stock Expert AI includes AI-powered MoonshotScore ratings, real-time top gainers and decliners, market-capitalization distribution charts, and a complete stock table. Our proprietary scoring model evaluates every company across nine quantitative dimensions including revenue growth, profitability margins, analyst consensus, insider activity, and technical momentum to produce an actionable 0-to-100 rating.

Industry analysis is a cornerstone of the top-down investment approach. By identifying which industries are outperforming their sector peers, investors can allocate capital toward secular growth themes while avoiding structural headwinds. The data below is organized by parent sector so you can drill from macro trends to micro opportunities in a single workflow.

The MoonshotScore is Stock Expert AI's proprietary 0-to-100 rating that evaluates each stock across nine quantitative factors including revenue growth, profitability, analyst consensus, insider activity, and technical momentum. Scores above 70 indicate strong growth potential, while scores below 40 suggest caution.

Our Analysis Methodology

Stock Expert AI evaluates every publicly traded U.S. stock using the MoonshotScore, a proprietary 0–100 composite rating. The score synthesizes nine quantitative dimensions: revenue growth trajectory, profitability and margins, analyst consensus estimates, insider transaction patterns, institutional ownership shifts, short interest dynamics, technical momentum signals, earnings surprise history, and valuation multiples relative to peers.

Price data is sourced from Financial Modeling Prep (FMP) with Yahoo Finance as a fallback. Fundamental data comes from SEC filings, FMP, and Alpha Vantage. Sentiment signals are derived from aggregated analyst ratings and news flow. All metrics refresh during market hours; after-hours data reflects the most recent closing values.

Sector and industry classifications follow the Global Industry Classification Standard (GICS), the same taxonomy used by S&P and MSCI. Companies are assigned to one of 11 sectors and further classified into 50+ industries based on their primary revenue source.
