Is there a way to know when institution is buying to the level of days instead of quarters?

Question

https://www.nasdaq.com/market-activity/stocks/amd/institutional-holdings

NASDAQ lists institution ownership only to the resolution of quarters. For example, the dates are 06/30/2021 which refers to the Q2 of 2021. Is three a resource that provide institution buying/selling days instead of quarters?

Answer 1

No. That's the whole point of the system.

There is a balance to be struck between regulatory necessity and commercial confidentiality.

Daily data is commercially sensitive, quarterly data is sufficient for regulatory purposes.

Bonus answer:

I would also take a moment to warn you against trying to trade off institutional ownership data. It is inherently dirty data:

• It is (as you discovered) historical data covering a large period.
• It doesn't have the necessary level of detail to make it useful (i.e. own-book vs client).
• If the institution operates certain types of fund, you might be merely seeing the result of quarterly window-dressing.
• Many other aspects
