How we work this out

ARK publishes every fund's full holdings each day. We compare each day with the one before. When money flows into a fund, ARK buys more of every stock by the same percentage, so we strip that out and count only the moves beyond it as real decisions. Dollar values are estimates: shares traded × that day's price from ARK's own file.
