Insiders: The reason that it matters is at some point, somebody is left holding the bag.
Today, you have record numbers of CEOs selling their stock.
A great indicator markets are bad is when, at peak prices, companies are buying shares to continue to prop up their stock.
And maybe the incentive structure of their CEOs is based on their share price.
The only thing that mattered was pump the stock.
And if you're along for the ride, that's great.
But when the CEO starts selling—now 10 billion in Musk’s case and billions of dollars in many other cases—the people left holding the bag are the people that were last in.
The tragic thing would be if those people are lower-income or lower-middle-income people that shouldn't be gambling or speculating, but they see all of their friends making money, their stock portfolios getting bigger, and they are lured deeper and deeper at the worst time.
