Knight Capital Group Chief Executive Officer Thomas Joyce said in a letter to clients yesterday the company is “in good standing” with clearing firms and its broker-dealer units have sufficient capital. Joyce also said the post-tax loss stemming from Knight’s trading error was about $270 million, compared with a previously reported pretax loss of $440 million. The letter comes a week after Knight, one of the biggest market-making firms in the U.S., was driven to the brink of bankruptcy after a technology malfunction spewed orders into the market by mistake.
