A Quiet Period is a set amount of time when a company's management and marketing teams cannot share opinions or additional information about the firm.The purpose of this is to allow the company to release accurate and unbiased information to the public. This allows potential investors to make informed decisions about whether or not they want to invest in the company.Quiet periods typically last for 30-60 days before an initial public offering (IPO). During this time, companies are prohibited from making any type of announcements that could potentially impact their stock price. This includes things like earnings reports, new products, partnerships, etc.After the IPO, companies are free to start sharing this type of information again.
