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 uses a fixed Russell 1000 baseline universe, 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.
