在量化交易引起了广泛讨论后，中国证监会上周五表示，程序化交易在特定市场环境下存在加大市场波动的风险，有必要因势利导促进其规范发展。请看本报昨日的报道：

China’s securities regulators tightened scrutiny over program trading, also known as quant trading, Friday, seeking to better regulate the use of computer-generated algorithms in stock trading.

The new rules comes after a raft of stimulus measures by the China Securities Regulatory Commission (CSRC) failed to drive a sustained market rally, for which some blamed apathetic selling from program trading.

报道中的quant trading即quantitative trading，也可以叫program trading，指“量化交易”，即基于量化模型和计算机数据处理作出的交易决定，此前是部分机构和对冲基金采用的交易方式，现在也被一些个人投资者接受。
