华尔街股票交换十分频繁，甚至前1分钟购买的股票在后一分钟就转手出售了。密苏里大学经济学教授Michael Hudson称，平均每只股票持有的时间为22秒，比一年前的20秒要改进不少。Hudson称，金融业是分秒必争，一切兼源于计算机化的快速交易系统。70%的交易都是通过高频交易系统完成的。个人投资者如何与电脑竞争？
What, you bought a stock one whole hour ago? And you still own it? That stock is practically a dinosaur in Wall Street's new reality.
The average time a stock is held is 22 seconds. But that's an improvement from a year ago, when it was 20 seconds, according to analyst Michael Hudson, an economics professor at the University of Missouri.
It's all because of computerized split-second trading. "The financial sector is short term," Hudson said in an interview. "They talk as if they're long term."
Wired has an excellent overview of how computerized trading has taken over Wall Street. It's so bad now, in fact, that computers now read news articles at lightning speed, searching for key words that will help them buy stocks. Post continues after video:
"The machines aren't there just to crunch numbers anymore; they're now making the decisions," Wired reports. Computerized high-frequency trading makes up about 70% of all trades, experts say.
How can the individual investor compete with that?
