who were invited ? and why ? imo most of the invited are not stock investors, but personalities in the entertainment industry, sports and media, maybe and only a handful interested inthe stock price ! And those interested calls their brokers for 10 -20- 30- 40- 50- million shares at a predetermined average price which the brokers will try to deliver !
Most of the people at that party were already rich! I doubt many of them sit at home everyday watching the stock market. I am sure some will buy though on a non Holiday week.
