高频率交易 – Are you a HFT or a sucker?

两天前看了思托沃特（Jon Stewart）的晚间秀 – Dailyshow, 有一个小品讲的是高频率交易，非常好笑，和大家分享：

 小品后，思托沃特打趣道：如果有人在一天前获悉市场交易的消息，是“内幕交易”的话，那在一秒前市获悉场交易的消息，是什么交易呢？

 由此联想到玛莎·思托沃特 （Martha Stewart）当年因为在ImClone 的股票下跌前一天，卖出了仅区区3,928股的ImClone 股票，而被SEC 起诉“内幕交易”，最后入狱半年加罚款。真不知道她会对今天的股市，特别是“高频率交易”怎么想。

 股市自昨天开始调整，今天传来失业率上升的消息，但是如果你是高频率交易者，你还需要市场消息吗？
