The ARK Invest web app provides a weekly update of ARK's combined ETF holdings. The data shown in this web application is updated every weekend and all calculated buy/sell values are based on the previous two updates (one week apart). The source is the ARK Invest website where the company publishes their holdings for each publicly traded ETF: https://www.ark-funds.com/.

Sort modes: Amount ranks by ARK's current combined holding size for each stock (in $ mode this is total holding value, in Num. Shares mode this is total shares held). $ Change ranks by the dollar value of the buy/sell change over the selected timeframe. % Change ranks by the percentage change shown in green/red under each row. On the Buys and Sells tabs, the large number still shows the amount bought or sold over the timeframe, so the list can look different when Amount is selected or when the current display mode differs from the sort mode.
