What Is the Expert Market, and Why Can't I Sell My Shares?

The short explanation of the tier that traps retail shareholders, and what it means for your position.

If a broker tells you a stock is on the Expert Market, or you see it marked unpriced or not available to trade, this is usually why.

The one-sentence version

The Expert Market is a restricted tier of the over-the-counter market where broker-dealers cannot publish public quotes, because the company is not making current information available. Trading there is limited to certain professionals, so most individual investors can neither buy nor sell.

The weekly Flags Watchlist: small-caps now showing dilution or promotion signals, each linked to the SEC filing behind the flag.

How a stock ends up there

In September 2021 the SEC's amended Rule 15c2-11 took effect. The rule says a broker-dealer may only publish a quote for a security if current information about the company is available to the public. When a company stops filing, brokers must stop quoting it, and the security moves to this restricted tier. More than two thousand companies moved on the day the rule took effect, and others have followed as they fell behind on filings.

What it means for you

Your shares still exist and you still own them. What you have lost is a public market to sell them in. Whether that is temporary or permanent depends almost entirely on whether the company starts filing current information again. For a company that is simply behind, there is a path back. For one that is insolvent or has gone dark for good, there usually is not.
