What it is:
How it works/Example:
For example, let's assume that Company XYZ is a tech company with growing revenues but growing losses. Its stock, which trades on the New York Stock Exchange (NYSE), is valued at $20 per share even though the book value of the company is only $1 per share and its inexperienced management knows little about how the grow the company successfully. Nonetheless, Company XYZ gets a lot of press, does a lot of marketing, and has a charming sock puppet for a mascot. This fuels hype for the stock, which motivates people to bid the price up in order to get their hands on some shares. In reality, Company XYZ shares are goldbrick shares -- their value is based mostly on hype.
