Professional model development and validation
How the Qualtix stock research model was built and validated
Qualtix scores any US stock with SEC filings using FMP fundamental data. The model is tested on a fixed baseline universe of 1,170 US stocks, with point-in-time filing controls and SPY benchmark comparisons.
The live Qualtix model is implemented as a deterministic scoring workflow. It separates business quality, valuation, entry timing, red flags, and data confidence before presenting a verdict.

Data The Model Uses
- SEC filing-based fundamentals accessed through FMP where supported.
- Company profile fields such as market capitalization when available.
- Market price, momentum, benchmark, and sector context used for timing and risk checks.
- Data quality controls for filing lag, share-count drift, missing metrics, and extreme market-data anomalies.
How Scores Are Produced
- Business quality is evaluated separately from valuation so a strong company is not automatically treated as an attractive setup.
- Entry timing is evaluated separately from both quality and valuation because price action can change faster than fundamentals.
- Red-flag and exclusion checks can prevent a superficially attractive stock from receiving a clean verdict.
- The displayed score is the model output shown to users; AI explanation is downstream of that score.
What The Model Does Not Know
- It does not predict unexpected news, future management decisions, litigation, regulatory shocks, or sudden macro events.
- It cannot guarantee that strong business quality will produce strong stock returns.
- It cannot know whether an elevated valuation will normalize quickly or remain elevated for a long time.
- Its output can change when price, fundamentals, filings, or data quality change.
