Maybe game changing news (like positive or negative TLD) is imminent from Schwab’s perspective though they probably know less than we do.

As the Reddit crowd found out, trading can be halted because the share price can be doing too well.

It is just the notice that the SHO short sell restrictions are in effect.

Not sure why, but I got to fly. So goodby. :-)

EDIT: I do not have a Schwab account. So I do not know if they have flagged it or not. Only saying what the flag would mean.

JRII, I don't see that (regulatory circuit breaker) on my schwab, not on account summary or detailed quote. Also not sure what that would mean.

NASDAQ:
The U.S. equity, options and futures exchanges have established procedures for coordinated cross-market trading halts in the event of a severe market price decline. These procedures, known as market wide circuit breakers, may halt trading temporarily or, under extreme circumstances, close the markets before the normal close of the trading session.

The SEC recently approved a joint exchange plan to modify the market wide circuit breaker rules in the following manner:

Reduce the market decline percentage thresholds needed to trigger a circuit breaker to 7%, 13% and 20% from the prior day's closing price, rather than declines of 10, 20 or 30 percent.
Simplify the market circuit breaker rules by reducing the number of relevant trigger time periods and trading halt durations.
Use the broader S&P 500 Index (rather than the Dow Jones Industrial Average) as the pricing reference to measure a market decline and require that the trigger thresholds be recalculated daily (rather than quarterly).
The revised Market Wide Circuit Breaker rule 2013 was implemented Monday, April 8, 2013. For messaging details, refer to the approval order on the SEC website.

I have not seen it yet. It certainly could signify impending news, but it is not just triggered on a drop, a circuit breaker is neutral also is triggered in a rapid rise.

“Limit Up-Limit Down Mechanism – On May 31, 2012, the SEC approved a “Limit Up-Limit Down” mechanism to address market volatility by preventing trades in listed equity securities when triggered by large, sudden price moves in an individual stock. The limit up-limit down mechanism is intended to prevent trades in individual securities from occurring outside of a specified price band. This price band is set at a percentage level above and below the average price of the stock over the immediately preceding five-minute trading period. These price limit bands are 5%, 10%, 20%, or the lesser of $.15 or 75%, depending on the price of the stock. Additionally, these price bands double during the opening and closing periods of the trading day. If the stock’s price does not naturally move back within the price bands within 15 seconds, there will be a five-minute trading pause.”

“The single-stock circuit breaker is designed to prevent trades from occurring outside specific price bands of a security, which are 5% above and 5% below the average reference price of a security in a 5-minute interval. This means that a circuit breaker is activated for a stock if it trades up or down 5% from its set average price in a 5-minute interval. Trading is halted for 5 minutes but can be extended to 10 minutes.”
