Total: 66.90 GB of Parquet (zstd), 6,083,105,065 rows. Built 2026-10-30.
Layout
Each symbol is stored once: data/stocks/1m/<FIRST_LETTER>/<SYMBOL>.parquet (non-letter symbols under 0-9/), data/options/1m/<UNDERLYING>/<EXPIRY_YEAR>.parquet, data/futures/1m/<ROOT>.parquet, data/futures/tick/<ROOT>/…, data/indices/1m/…, data/vix/…, data/fed_rate/daily/…, data/macro/daily/…, data/other/<dataset>/part-*.parquet.
Groups (DIA30, NAS100, SP500, …) are configs that point at those same files, so nothing is duplicated. Membership lists are in groups/<GROUP>.csv.
Timestamps (ts) are UTC. Options right is C/P; expiry is the expiration date.

Any config name from the table works the same way. Big configs (all_stocks, options) are best streamed (streaming=True) or read one file at a time:
import pandas as pd
aapl = pd.read_parquet("hf://datasets/syncster-data/historical-market-data/data/stocks/1m/A/AAPL.parquet")
spy_opts_2025 = pd.read_parquet("hf://datasets/syncster-data/historical-market-data/data/options/1m/SPY/2025.parquet")
Group notes
- DIA30, NAS100 and SP500 membership is the published index constituents as of 2026-10-25, limited to symbols that have data here.
- RUT2000 is an approximation: US companies ranked 1,001-3,000 by market cap on 2026-10-21.
- Market-cap tiers use market cap on 2026-10-21: Large > $10B, Mid $2B-$10B, Small $300M-$2B, Micro $50M-$300M, Nano < $50M. Symbols without a market cap (mostly ETFs and funds) are in
other_stocks_etfs. - Indices include the cash index series plus the major index ETFs.
