Our Take
Portfolio123: Portfolio123 is the most powerful quantitative screening and backtesting platform available to retail investors. Its combination of institutional-grade FactSet data, 20-year point-in-time backtesting, multi-factor ranking systems, and commission-free broker integration creates genuine analytical depth that no consumer alternative matches. The learning curve is steep and the interface is dated, but for systematic investors willing to invest the time, no other platform delivers this level of quantitative rigor at $25-83/month.
Pricing Comparison
Portfolio123 Pricing
Portfolio123's pricing is straightforward and competitive for the depth of tooling it provides. The free tier includes broker integration with Tradier and Interactive Brokers, fundamental charting, and a consolidated brokerage account view — useful but limited for research. The Screener plan at $25/month unlocks the full financial database, 460-plus screening metrics, and five years of backtesting data. The Pro plan at $83/month adds 20 years of backtesting, multi-factor ranking systems, rolling screens, position sizing, and API access. Annual billing saves 28% on Retail plans and 23% on Pro plans. A 21-day trial at $19 provides full Pro-level access with 10 years of data and no auto-renewal — a low-risk way to evaluate the platform. For context, Stock Rover Premium Plus costs $28/month with shallower backtesting, while Trade Ideas starts at $118/month for a narrower use case.
What Users Say
Portfolio123
User sentiment is overwhelmingly positive among those who invest the time to learn the platform. On Trustpilot (4.8/5, 50 reviews), 88% of ratings are five stars — an unusually high concentration. Users describe it as "the best quant platform for retail users" and "simply the best product for quantitative stock analysis." Several long-term members report that Portfolio123 "genuinely changed my life as an investor," citing the shift from intuition-based to systematic, data-driven decision-making. Professional reviewers at GreatWorkLife and LiberatedStockTrader both award 4.1/5, praising screening depth and backtesting power while noting the learning curve. The sole recurring negative theme is the steep onboarding — not the platform's capability or value. One Trustpilot reviewer gave a single star citing community dynamics, but this is an extreme outlier against 49 four- and five-star ratings.
