Further to that post, "The quiet period precedes the introduction of a company into the capital market. During that time, the amount of public exposure and hype must be minimized to hinder any potential interference with SEC efforts to evaluate its filings and the release of any information which may cause investors to "jump the gun" on valuations and expectations for the company. The SEC's intention is to create a level playing field for all investors in the capital market, ensuring that all have the same information about the company when it goes out for sale on the market."

To be clear, I was not meaning "quiet period" in this precise legal context, but who knows?
