Business Use Cases
How businesses use Financial Market Data data to make better decisions:
- Market data aggregation
- Financial research automation
- Portfolio monitoring
- Quantitative analysis data feeds
How It Works
Identify target financial data sources and tickers
Provide URLs from financial sites like Yahoo Finance, Macrotrends, or Finviz for the stocks, indices, or financial metrics you need. Most financial sites have consistent URL structures based on ticker symbols.
AlterLab retrieves the publicly visible financial data
Financial websites load market data via JavaScript in real-time. AlterLab renders the complete page and captures current prices, historical data, analyst ratings, and financial metrics as they appear to any visitor on the site.
Get market data structured for analysis
Receive stock prices, P/E ratios, market cap, trading volume, analyst consensus ratings, price targets, earnings estimates, and sector classifications — all from publicly available financial pages and ready for your investment research or portfolio tools.
Key Insight
Public financial websites like Yahoo Finance and Macrotrends provide most of the data that non-institutional investors need — current prices, historical data, analyst ratings, and key financial ratios. AlterLab lets you automate collection of this data at a fraction of the cost of enterprise data subscriptions, which are designed for institutional traders needing millisecond-latency feeds.
Data Freshness
Stock prices update in near-real-time during market hours (delayed ~15 min on free financial sites). For intraday trading data, collect every 15-30 minutes during market hours. For fundamental analysis data (P/E ratios, earnings estimates), daily or weekly collection is sufficient as these metrics update on earnings schedules.
