Looking at the 13F filings is also a great way to track what Ark and other investors (like Buffett) are investing in: https://cheaperthanguru.com/portfolio/cathie-wood

Not really. 13F filings are quarterly with a 45 day delay. ETF holdings are published daily with no delay on the Issuers website.

Eh, my buddy runs a hedge fund that uses aggregate 13F info to generate alpha. Individually 13F filings may not be accurate, but taken together they can be very valuable.

If there's any trade its a "mean reverting" one - would be my educated guess.
