[ by Howard Haykin ] Knight Capital Group Inc. (KCG - part of the C-I Financial Index), a leading market maker in the U.S., estimates that it lost as much as $35 million trading Facebook Inc. (FB) on that stock's first day of trading - 5/18/12.  And KCG places the blame squarely on Nasdaq OXM, and has filed a claim against Nasdaq OMX to recover that amount. Claims were submitted to Nasdaq, though "there are no assurances that the company will be able to recover any of its losses resulting from the numerous issues and problems at Nasdaq," according to a filing today with the SEC.  As such, the company is "evaluating all remedies available under law." Total Losses of $100 Million. Knight CEO Thomas Joyce said in an interview on 5/21 that he "wouldn’t be shocked" if total brokerage losses from the IPO reached $100 million. Technical problems simply ruled the trading session on Friday, 5/18 - and they began before the opening bell.  Nasdaq OMX’s computer systems used to establish the opening price for Facebook were overwhelmed by order cancellations and updates during the "biggest IPO cross in the history of mankind," according to Nasdaq OMX CEO Bob Greifeld. After those problems were repaired, more technical issues arose.  In one instance, order updates for 30 million shares didn’t participate in the auction because of an error, Nasdaq reported in a notice the next day.  Reports of who received executions in the cross were delayed until 1:50 p.m. ET on that day, Friday, 5/18. Placing Blame. "This wasn’t in any way, shape or form an industry failure," Joyce told CNBC.  He said Nasdaq should have delayed trading, possibly to May 21.  "It wasn’t a systemic issue.  The failure was Nasdaq’s."
