This page describes how StrongBuyAnalytics retrieves third-party data, applies deterministic transformations, and presents research outputs. The platform contains feature-specific methods; it does not use one universal five-pillar model or one weighting scheme across every page.

The requested feature determines the provider path. Chart history may combine Polygon historical bars with recent Yahoo bars; intraday charts use Yahoo first and Polygon as fallback. Other implemented surfaces use Alpaca, SEC EDGAR, Financial Modeling Prep (FMP), CoinGecko, social/search feeds, news providers, or OpenAI. Provider availability, entitlement, symbol mapping, and asset type can change which fields are returned.
A retrieval timestamp is evidence that the application ran, not proof that every underlying observation was created at that moment. Filing period dates, market timestamps, and provider timestamps are the relevant freshness evidence where available.
Application code standardizes symbols, dates, intervals, numeric fields, and table shapes before calculating ratios, trends, chart indicators, valuation scenarios, or feature-specific classifications. Calculations depend on available inputs. For example, a report DCF is unavailable without positive free cash flow and a valid share count, and the standard corporate DCF is intentionally skipped for financial-style companies.
The fundamental report assigns points through defined section rules. Its overall rule score excludes the ten_year section and converts earned points over available maximum points to a 0–100 percentage. Separate confidence and freshness logic can suppress or qualify classifications. Statements no more than 120 days old are labeled fresh; 121–240 days stale; older statements very stale; unavailable dates are unknown.
Report labels describe fundamental quality and, when available, valuation attractiveness. They are research classifications—not Buy, Sell, or Hold recommendations. The simpler stock-page labels belong to a different calculation.
The five-input stock-page screen retains a reported finite zero and applies its own threshold: zero revenue growth is in the “0% or lower” band; zero gross margin is in the “35% or lower” band; zero net margin and zero return on equity are in the “0% or lower” band; and zero debt/equity is in the “below 0.30” band. Missing, invalid, and non-finite values are not scored as zero. A ratio with a zero denominator is undefined, not a measured zero. The separate report DCF requires positive free cash flow; a measured zero or negative TTM cash flow does not qualify for DCF.
OpenAI is used on implemented features to turn supplied data and computed results into readable narrative. It is not the source of exchange prices or SEC filings, and deterministic score arithmetic does not depend on the model inventing points. If AI access is unavailable, some paths use deterministic text while others may omit narrative or report an error.
Generated prose can still misstate, omit, or overemphasize facts. Readers should inspect the displayed tables, dates, assumptions, and primary filings rather than treating narrative as an authoritative record.
A user requests a daily equity chart and a fundamental report. The chart path requests Polygon history and Yahoo recent bars, merges available results, and caches the resulting series for its configured interval. Separately, the report loads its implemented financial datasets, computes section tests, excludes ten_year from the overall rule-score denominator and numerator, and normalizes the included points. If the included sections total 42 of 60 points, the result is 70.0. A narrative may explain those results, but it does not change the deterministic 42/60 arithmetic. Provider timestamps or filing dates may predate the page-generation time.
