Coverage depends on each instrument
Daily prices may extend back 30+ years for some established instruments. A recently listed company, a security that changed symbols or a less detailed international filing will necessarily provide a shorter period.
Annual and quarterly statements, ratios, dividends, estimates and transcripts each have their own depth. AInvestor presents the observations actually received instead of promising one uniform number of years.
Available data categories
Depending on the instrument, AInvestor can connect quotes and price history, income statements, balance sheets, cash flows, ratios, metrics, dividends, sector data, commodities, news and market sentiment.
Canonical fields normalize shared concepts across providers. Source data, deterministic calculations and artificial-intelligence-assisted interpretations remain separate to preserve traceability.
Freshness controlled by data type
A quote changes more quickly than an annual balance sheet. AInvestor therefore applies validity periods suited to each category: volatile data is checked frequently, while fundamentals are updated after new publications.
Commodities are refreshed automatically by a scheduled process. Security research progressively enriches historical and fundamental data when its validity period has expired.
No invented values to fill a history
A missing period remains missing. AInvestor does not artificially extend a series, turn a missing value into zero or present a ratio as reliable when its source data is insufficient.
This transparency shows the period on which a trend, simulation or reading was actually calculated. Results support learning and independent research; they are not a recommendation to buy or sell a security.
