SEC rules say that underwriters (i.e. most of Wall Street) aren't allowed to hype their own handicraft until a suitable number of days have passed. The length of this "quiet period" keeps changing, but according to this article, it's now 10 days on the books, with most underwriter/analyst firms choosing to play it safe and observe 25 days of restraint.
What is a underwriters/handicraft? Are they writers paid by the company to write bearish articles about them and have 'no' affiliation so there's no disclaimer?
In an IPO, the underwriters are the investment banks who handle the initial distribution of the stock. From Wikipedia:
"Securities underwriting refers to the process by which investment banks raise investment capital from investors on behalf of corporations and governments that are issuing securities (both equity and debt capital). The services of an underwriter are typically used during a public offering in a primary market.
This is a way of distributing a newly issued security, such as stocks or bonds, to investors. A syndicate of banks (the lead managers) underwrites the transaction, which means they have taken on the risk of distributing the securities. Should they not be able to find enough investors, they will have to hold some securities themselves. Underwriters make their income from the price difference (the "underwriting spread") between the price they pay the issuer and what they collect from investors or from broker-dealers who buy portions of the offering."[1]
When the comment above said "underwriters aren't allowed to hype their own handicraft", the "handicraft" he's referring to is the new stock that they just distributed, and hyping it generally takes the form of the banks' analysts issuing "buy" recommendations.
