The sales are part of a 10b5-1 plan entered into in March which is designed to allow company execs to sell shares in their company without it alarming investors.

Huang sold 100,000 Nvidia shares in two transactions last Friday and yesterday worth $14.4 million. A filing shows that the sale of another 50,000 shares is planned soon.

Before last week, Huang is reported to have sold about $1.9 billion worth of Nvidia shares.

Huang has Nvidia shares worth about $126 billion making him the world’s 12th richest person.
