Before inviting Buffett to dinner, the young man had already bought those stocks at a low price and cashed out at the peak, making far more money than what it cost to treat Buffett to a meal.
It was after that event Buffett clearly stipulated that stock-related topics were forbidden during his meal engagements.
Everyone in the stock-trading community knew about this.
However, even those not involved in trading knew that not long ago, to ensure that a certain star got more screen time, middle-aged men had managed to drive up the stock of that toilet company by several times.
Jie Qingshuai, who claimed to be a billionaire, caused the stock of a company he had previously worked for to skyrocket for several days.
