What about the Gray Sheets?
A Grey Sheet company is a Pink Sheet company that has not filed a 15c2-11. Due to this fact, all orders to purchase the accompanying stock must be unsolicited and the issue is “non-piggyback” qualified for market makers. This means that each market maker is responsible for conducting their own due diligence and cannot rely upon the due diligence of another market maker who has previously quoted a bid or ask price for the stock.
There are no market makers in a Gray Sheet Company’s stock. It is not listed, traded or quoted on any stock exchange, the OTCBB or the Pink Sheets. Trades in grey market stocks are reported by broker-dealers to FINRA and FINRA distributes the trade data to market data vendors and financial websites so investors can track price and volume. Because grey market securities are not traded or quoted on an exchange or interdealer quotation system, investor’s bids and offers are not collected in a central spot so market transparency is diminished and Best Execution of orders is difficult.
Gray Sheet Companies may have been created under questionable legal circumstances.
For these reasons, most professional advisors will advise you to steer clear of attempting to get a Gray Sheet listing.
