Where each one shines

What Portfolio123 and QuickFS each do best.
Show
Portfolio123 logo

What Portfolio123 does best

  1. Tools for building multifactor ranking systems, stock screens, ETF screens, and complete rules-based strategies through a web research environment.
  2. Tools for running simulations and backtests with long historical equity data, custom universes, buy and sell rules, position sizing, hedging, rebalancing, and realistic assumptions.
  3. Point-in-time data designed to avoid survivorship and look-ahead bias, with fundamentals, estimates, corporate actions, sector and industry classifications, and historical issues.
  4. Tools for creating ranking systems from fundamental, technical, sentiment, and macro factors, including public factor documentation and FRED-linked economic series.
  5. AI Factor to train machine-learning predictors for expected returns and feed those predictions into rankings, simulations, and asset-level analysis.

What QuickFS does best

  1. Official homepage says QuickFS will not relaunch and that the founder introduced FastFS.org to a data vendor that could support a successor with major QuickFS-like features.
  2. Legacy product offered 20-year history for 200+ standardized metrics and statements across 40,000+ international stocks.
  3. Legacy Excel add-in used =QFS("ticker","metric","period") to pull data directly into models; Microsoft AppSource listings may still exist but require a QuickFS account and should not be treated as an active standalone service.
  4. Legacy API and exports covered fundamentals, market data, company metadata, CSV/Excel exports, and bulk downloads; current official homepage does not advertise active API access.
  5. Ticker format with country suffix (e.g., AAPL:US) and global coverage across U.S., Canada, Europe, Australia, and more were legacy capabilities.

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 Pricing, features, and availability may be incomplete or out of date.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.
