Estimated investor money in (+) or out (−) of each ETF, from the daily change in the fund's share counts. This is investors buying or selling the ETF itself, not Cathie Wood's decisions — the fund then buys or sells every holding in proportion, which is why those moves are left out of the trades above.

Calmest to wildest over the past year (volatility): ARKW → ARKX → ARKF → ARKQ → ARKK → ARKG. Volatility is how much the fund's price swings in a typical year; max drop is its worst fall from a peak over 5 years; beta above 1 means it tends to move more than the S&P 500.
