What is the meaning of lock up expires? What happened after that?

Millionaire one day : When a "lock-up" expires, it refers to the end of a period during which certain shareholders or insiders (such as company executives, employees, or early investors) are restricted from selling or trading their shares in a company. This typically occurs after an initial public offering (IPO) or a major funding round.

The lock-up period is put in place to prevent large amounts of stock from being sold immediately, which could negatively impact the stock price. Once the lock-up period ends, these insiders are allowed to sell their shares on the open market, which can result in increased trading volume and potentially affect the stock's price.

In summary, the expiration of a lock-up means that previously restricted shareholders are free to sell their shares, which can lead to significant changes in the market dynamics of the company's stock.
