Washington Post Stock Up 100%, Triggers Circuit Breaker After Errant Trades 225,000% Above NBBO Fry System
Update: According to Bloomberg, this was yet another mini flash crash, where an errant trade somewhere, somehow caused a massive surge in the price as several trades cross at $900+, a few million percent above where the stock has been trading in forever. The stock has now resumed.
Not sure what reason is just yet. But at least those new circuitbreakers get a workout... to the upside.
