Quant Stock Screener: Rank Factors with Auditable Evidence
Build a transparent screen across quality, momentum, valuation, liquidity, volatility, and news risk.
Published: April 09, 2026 · By the QVeris Team
What Is a Quant Stock Screener?
A quant stock screener ranks stocks using measurable factor signals. Investors use quality, momentum, valuation, liquidity, volatility, and news risk to build candidate universes and compare stocks with a repeatable framework.
This QVeris scenario uses quant stock screener as the search entry point, then connects it to the QVeris Quant Factor Screen skill. The workflow helps agents screen many stocks, explain factor-driven rankings, and return source-backed analyst memos.
What a Factor Screener Should Rank
A useful quant screen combines factor scores with source context, exclusions, and explainable ranking logic.
Quality Factors
Rank profitability, balance-sheet strength, earnings quality, margins, return on capital, and operating consistency.
Momentum Factors
Track price momentum, earnings momentum, estimate revisions, relative strength, and trend persistence.
Valuation Factors
Compare multiples, free cash flow yield, earnings yield, revenue multiples, and valuation dispersion.
Liquidity Factors
Screen trading volume, spread risk, float, market cap, turnover, and position sizing constraints.
Volatility Factors
Measure drawdown risk, realized volatility, beta, gap risk, and factor instability across regimes.
News Risk
Flag earnings events, filings, analyst changes, product news, regulatory risk, and unusual catalyst context.

Static Stock Screener vs QVeris Factor Workflow
| Need | Static stock screener | QVeris factor workflow |
|---|---|---|
| Build a candidate list | Sort by fixed columns and manual filters | Ranks stocks with explainable factor logic and source notes |
| Explain rankings | Analyst manually interprets why a stock scored well | Returns factor contribution, evidence strength, and missing data |
| Blend signals | Fundamentals, price action, liquidity, and news are separated | Combines factors into a reusable workflow and analyst memo |
| Repeat at scale | Manual refresh slows down across universes | Reusable AI agent workflow for recurring factor screening |

Open the Quant Factor Screen skillHow to Evaluate Quant Screener Results
A quant stock screener should not be judged only by how many tickers it returns. For an AI investment research workflow, teams should inspect whether the screen explains the factor definition, reporting period, data freshness, ranking method, and exclusion rules. A transparent workflow also separates exploratory factor discovery from production portfolio decisions, so the agent can present candidates without overstating certainty.
QVeris-style capability routing helps because the agent can discover factor, fundamentals, price, filings, and news capabilities separately, inspect their schemas, and then combine them into a traceable screening workflow. That makes the screener more useful for research teams that need evidence and repeatability, not just a static watchlist.
