IWM data FAQ

Why do early IWM prices look so low?

Because the data is split-adjusted. IWM had a 2-for-1 split in 2005, so every price before the first split is divided by 2. That keeps the whole history comparable with today's price and the returns correct. Choose "Unadjusted" if you need prices as originally traded.

How are IWM dividends adjusted?

IWM paid 79 cash dividends in the data period, most recently $0.750436 per share with an ex-date of 2026-09-15. Each dividend gives a factor of 1 − dividend ÷ prior close, and every price before the ex-date is multiplied by it. Many sources only adjust for splits, which leaves a fake drop on every ex-dividend date in your returns.

Why does the data start on 2003-09-10 and not the listing date?

IWM listed on 2000-05-22, but our minute-level history begins on 2003-09-10. Earlier data isn't available.

Do you have overnight (20:00–4:00 ET) data?

Not yet. The data comes from the consolidated tape (SIP), which covers 4:00–20:00 ET. US exchanges plan to add overnight trading to the SIP from 2026-12-06, and we will follow.

Can I keep the download up to date with the API?

Yes. Downloads and the market data API share the same data and the same adjustment. Download the history once, then pull each new day from the /v2/aggs endpoint.
