US stock market data for UK Investors

US stock market data for UK investors

FinzData provides US stock market data UK users need for research on US-listed stocks and ETFs. The service covers every US stock including delisted companies, plus 231 ETFs, with history going back more than 26 years. Bars are available from 1-minute to daily and point-in-time fundamentals are sourced from SEC filings. Macro data is provided with vintages as first published and CFTC COT positioning is included for futures context.

UK readers often research names they know from domestic markets that trade in the US. Shell, BP and Unilever are examples of well-known companies from the UK that have US-listed shares or ADRs and can be researched in US data. FinzData covers US-listed stocks and ETFs, not local exchanges.

The US regular session is 9:30 am to 4:00 pm New York time. For most of the year this is 2:30 pm to 9:00 pm UK time. That window fits after the UK working day and allows evening review of prints, closes and news for US names held in ISA and SIPP research workflows.

API access and data formats

Access is via a Python package pip install finzdata and a REST API that returns JSON, CSV and parquet downloads. The API supports point-in-time queries for fundamentals and macro vintages, 13F institutional holdings, and end-of-day options chains for US stocks and ETFs with nightly dealer gamma levels as a $29 a month add-on.

Pricing is in US dollars and paid by card. One ticker from $19 and whole US market from $195 once plus $19.95 a month. A free API key, no card, 1,000 calls a day is available for testing.

Use cases for UK research

The macro series with vintages as first published supports analysis of policy shifts and market reactions. CFTC COT positioning provides weekly commitment of traders data for context on futures markets that influence US equities.
