What is a grey market in trading?
By taking a position on a grey market, you’re taking a position on a company’s potential market cap ahead of its initial public offering (IPO). The price of a grey market is a prediction of what the company’s total market capitalisation will be at the end of its first trading day.
If you think the estimated value of the company is over- or under-priced, a grey market enables you to take advantage of this disparity before the shares are released publicly on the stock exchange.
