Fund Net Assets Historical Data

Hi all,

(I tried to find this but to no avail, that’s why I am asking here):

Do you know of a resource of historical net asset for ETFs (the total value of the fund, not just daily volumes)?

Background: I do own big chunk of my portfolio in somewhat lower volume fund (VDEV: ~800 mil USD) and I am trying to decide if I am ok with keeping it. It is buy and hold.

Thanks!
