The QuantQuote Stock Valuation Metrics API delivers daily fundamental valuation ratios and market statistics for US-listed equities. These metrics provide a quantitative lens on how the market is pricing a company relative to its earnings, book value, sales, and overall enterprise value. Tracking these ratios over time is essential for value investing, relative valuation analysis, and building factor-based strategies.
Each daily record includes trailing and forward P/E ratios, price-to-book, price-to-sales (trailing and forward), market capitalisation, enterprise value, dividend yield, and earnings yield. Data is available for a specified date range and returned in JSON or CSV format via a simple REST endpoint.
