Methodology & Limitations
Version 1.3 · last updated 2026-07-30
How QMA computes its analytics — without publishing exact proprietary weights, but enough to understand what a result means and what it does not. QMA is an analytical and educational tool, not investment advice.
Analytical methodology: results are model-based and informational. They are not personalized investment recommendations and may contain errors or delayed data. Customers make all decisions independently.
Scoring — the 5 super-pillars
- Value — fair value + earnings quality.
- Momentum — technical strength, relative strength, trend.
- Smart Money — insider activity, institutional/13F, off-exchange, options (public/reported data).
- Sentiment — news sentiment + earnings-call tone.
- Catalyst — upcoming events and catalysts.
Scale & grades
Each pillar and sub-score is on a 0–100 scale; overall grades run A++ to F. Scores are relative to the universe, not absolute truth, and are descriptive — not a buy or sell instruction.
Missing data
When a pillar has no data, it returns "—" (not a fake neutral 50) and weights are redistributed only across available components. We do not fabricate.
Updates & regime
Scores refresh daily (liquid stocks multiple times per session). Weights adapt to the market regime (e.g. bear/volatile). The model version is shown with results.
Portfolio analytics
QMA describes your portfolio structure — concentration, risk, correlation, diversification — from data. It is a descriptive analytical view and model scenarios (e.g. projections, Monte Carlo), NOT portfolio management, rebalancing of your brokerage account, or personalized advice. Projections rest on assumptions (return, volatility) that differ in reality; they are not promises.
Backtests & paper simulations
A backtest is a historical simulation — not real trading, and not client performance. It may contain survivorship and look-ahead bias, does not perfectly model liquidity, spread, slippage, fees or taxes, and paper results exclude some real-world costs. Past performance does not guarantee future results.
AI (QMA Brain)
QMA Brain generates analytical summaries and research views from platform data. It is AI-generated research that can contain errors — verify important facts independently. It is not personalized investment advice, and Brain works with a simulated portfolio and virtual money; it does not connect to your broker.
Market data
QMA builds on public regulatory registries (SEC/FINRA), licensed market data, and its own analysis. Data may be delayed (by 15 minutes or more), cached, or erroneous, and is not a primary source of guaranteed real-time data. We show the source and age of data with results so you can verify the conclusion.
Limitations summary
- Every output is an analytical view, not a prediction and not a recommendation.
- Data may be delayed/erroneous; backtests and projections are simulations resting on assumptions.
- QMA does not execute orders, hold or manage funds, or provide personalized advice.
- Past performance does not guarantee future results.
