On SEC EDGAR ↗

Positions as of Dec 31, 2018, from ARK Invest's 13F filing with the SEC. A 13F lists a manager's US-listed stocks and options at a quarter end and is filed up to 45 days later, so the fund may hold something else today. It leaves out short positions, cash and holdings outside the US.

As of Dec 31, 2018. Changes are in shares against Sep 30, 2018, so a price move alone never reads as a buy or a sale.

The filing on SEC EDGAR ↗

Price is a stock's reported value over its shares at the quarter end. The estimated gain is the shares held at both quarter ends times the change in that price: shares bought or sold during the quarter add nothing, options are left out, and a stock split is read into the earlier share count and price.

What made money

From Q3 2018 to Q4 2018: 182 stocks held throughout, down $610.4M (−23.4%).
