FactorsToday Review, Pricing, and Features
FactorsToday publishes factor returns and stock exposures through web tools, downloads, and an open REST API. Its portfolio analysis, attribution, optimizer, factor builder, and hedge builder are research models, not brokerage or accounting systems.
Best for
- Quantitative researchers studying factor returns, stock loadings, correlations, and attribution.
- Developers who need no-key REST endpoints for factor and portfolio analysis.
Watch out
- The site exposes public tools and a no-key API but publishes no long-term access or commercial pricing policy.
- The output assumes familiarity with factor models, regression, exposures, and model risk.

Key features
- Factor dashboards report intraday and multi-period returns, z-scores, pair relationships, correlations, seasonality, and valuations.
- Stock pages use ElasticNet regression with cross-validation to estimate exposures across four nested models.
- Portfolio analysis accepts holdings, compares exposures with a benchmark, and applies user-defined factor-return scenarios.
- Performance attribution applies rolling ordinary-least-squares regressions to uploaded or pasted returns and exports results to Excel.
- The factor builder searches for stocks matching target exposures and displays simulated historical results.
- The hedge builder suggests stock and ETF positions subject to liquidity, concentration, and position-size constraints.
- The REST API covers factor history, screens, stock loadings, portfolio analysis, hedging, and related-stock results without an API key.
- API access is limited to ten requests per second per IP address. The publisher says open access is temporary.
- Portfolio analysis, attribution, and factor construction depend on model assumptions and may omit stock-specific risks.

Curation & Accuracy
This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).
Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
