While the investigation is continuing, the Wall Street Journal is reporting that technology staff at CBOE Holdings, Inc. (NASDAQ:CBOE) had already been aware of?software issues hours before last Thursday’s outage.?
The staffers had believed the issues could have been fixed at the company, which has been become the buzz by CBOE executives and external parties. One question to be answered is whether or not the exchange could have switched to a backup system to be on the safe side, reported the Wall Street Journal.
On Friday, it was somewhat business as usual at CBOE but it did incur a decline in market share for some contracts perhaps as a result of placing the exchange in the ‘ol “penalty box.”?
But another problem did show up on Friday as CBOE had informed customers that from Thursday,?”numerous” trades had surprisingly appeared in the exchange’s system after the market had closed. Working with OCC, CBOE was trying to get rid of the them, stated an exchange notice.?
From Friday,?CBOE had executed approximately 22% of option contracts vs. its 24% month-to-date averag, as shown by data from BATS Global Markets Inc. Its stock closed at $35.53, down 0.22%.?
