The Chicago Board Options Exchange, operated by CBOE Holdings (NYSEMKT:CBOE) 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.
