GOVT data FAQ
How are GOVT dividends adjusted?
GOVT paid 175 cash dividends in the data period, most recently $0.073641 per share with an ex-date of 2026-11-02. 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 2012-02-24 and not the listing date?
GOVT listed on 2012-02-14, but our minute-level history begins on 2012-02-24. 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.
