I think it's disingenuous to compare those two numbers. The mass majority of that trading is alogos trading within short time spans, not entities entering or exiting long positions. This includes all the market makers that have to hedge options under the insane stock volatility by exiting and enter both short and long positions as the stock moves. It further includes every flavor of HFT that can potentially syphon some value from high volatility combined with momentum. This volume doesn't tell us anything about the actual change in stock held by various entities nor how easily 70MM shares could be obtained from entities.
