Ironically, all these Tesla executives/insiders left hundreds of millions on the table by selling too early, and would have done much better hanging onto the shares they just acquired , going by their share sales track records, as Tesla shares had an incredible run over the last two years, rising nearly 2,000% since the company surprised investors with a profitable third quarter in 2019.It tells average people that, no one can 100% precisely predict the market, especially when gamblers are torn between selling and staying put at a critical moment(market plunge for example).
