Unsure about your table although it looks believable. Whats the source on it? From my report trading on 5 June only 2.8m shares traded but yours shows Morgan Stanley buying 3.8m worth of shares?

In counter to your points - if Institutional investors were split 50/50 Buy/Sell positions then if retail money is net buy (which it historically is) then that would tip the buy side up hence pushing a rally. Assuming Retail money makes up 10% of the money in the market on a given normal cycle - how would the market react if that doubled to 20%?

So lets say $9B institutional money v $1B retail money. That is now $2B retail money being traded. A 10% increase in liquidity is going to have an impact on prices. It'll amplify the buys, and the sells thus creating price distortion and ramps & crashes.

Very few experts I've asked give much credibility to the "retail money is moving this" but in isolated cases that looks to be the case (Airlines surge/Hertz etc)
