On Tuesday, the SEC extended its temporary rule restricting short selling on financial stocks including Fannie Mae, Freddie Mac, Lehman Brothers, Merrill Lynch, UBS, Bank of America and others. It remains to be seen what lasting effect the rule will have on the market – the initial action spurred a market recovery – but either way the rule has been a definite plus for OneChicago. The single stock futures (SSF) exchange has taken full advantage of the short selling rule by touting SSFs on the financial giants affected by it – Bank of America, Barclays, Citigroup, Deutche Bank, Goldman Sachs, Lehman Brothers, Merrill Lynch, etc. OneChicago CEO David Downey says that since the short selling rule was introduced, the exchange has seen some increase in business, especially in Fannie Mae SSFs. “Interestingly we have been taking many calls from traders who are taking another look due to the new rules,” he says, adding, “It still remains that the clearing members, ironically the very names that this ruling addresses, still resist letting the customers trade SSF.”
