ARKK data FAQ
How are ARKK dividends adjusted?
ARKK paid 6 cash dividends in the data period, most recently $0.7826 per share with an ex-date of 2021-12-29. 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 first day start at 10:26?
ARKK listed on 2014-10-31. On an IPO day the first trade only prints after the opening auction, around 10:26 in this case, so the first 1-minute bar starts then.
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.
