上市公司主席持有自己公司的股票是否

1. Yes.

2. The way how the CEO (and other executives) get the shares is the key of the profit.

Usually, the executives get the shares by exercising their stock options or award from the company. At that time, the company uses the stock's par value for the transaction.

Once the transaction is completed, these executives sell the shares in the open market in market rates.

Since the par value is usually way below market value, the difference will be the profit.
