The Chicago Board Options Exchange, operated by CBOE Holdings and the largest options exchange in the United States, early this morning reported on its website that some quotes were delayed or entirely unavailable for a 13-minute period beginning at 8:00 a.m. EDT.
It also said a "limited number" of orders that were canceled yesterday were executed this morning, and some orders that should have expired remained active. Shares in the exchange operator were down more than 3% at the time of this writing.
The technological mishap follows a glitch that caused a three-hour halt in trading last Thursday on the tech-heavy Nasdaq. Only two days before that, as CNBC reports, Goldman Sachs mistakenly flooded the market with bogus options trades likely to cost the bank tens of millions of dollars.
