SHANGHAI/SINGAPORE, Sept 26 (Reuters) - China's securities regulators have told market participants that tighter rules for programme trading were not designed to kill the business, but were a response to calls for more oversight, according Asia's largest financial lobby group ASIFMA. "There's no intent to be prejudiced against high frequency trading firms," said Lyndon Chao, ASIFMA managing director and head of equities and post trade. Quant funds in China include global players such as Winton, Two Sigma and D.E.Shaw though these three aren't members of ASIFMA. The rules "came out all of a sudden because the regulators might be facing pressure from investors suffering from recent poor stock market performance," he said. There are a lot of quant funds out there that do a great job of injecting liquidity when needed.
