Kuppy appears on Zer0es.tv and runs through shareholder unlocks in this episode of Short-Selling 101. In many IPOs and new SPACs, insider shareholders are restricted from selling shares for a certain period of time. The devil is in the details for when this supply comes to market. Kupperman walks through a couple of instances where the unlocking of insider shares can cause a major selloff in the stock. He reveals that these unlocks can be major catalysts for short-sellers and it’s extremely important to watch in newly public companies.
