Out of curiosity what resolution and time scale is useful. Is it fair to assume the most hedge funds are relatively good at tracking recent information and the value is in older archives that's hard to collect?

Also are event streams and large connect event graphs like Forge.AI what sells actually useful?

Curious as my phd research potentially has applications for information extraction and event linking. But not entirely sure if those applications are actually valuable

No, like he said the most valuable data has a signal that is independent from other data sets, which generally means something proprietary, and almost always without a long history. Having a cleaned archive of standard data with a long history is valuable but already pretty well served. It would be hard to compete with CRSP.
