8/22/2013 2:07:00 PM Nasdaq halts trading due to technical issue
NEW YORK (AP) — Nasdaq halted trading Thursday because of a technical problem, the latest glitch to affect the stock market.
The exchange sent out an alert to traders at 12:14 p.m. Eastern saying that trading was being halted until further notice because of problems with a quote dissemination system. More than an hour later, trading was still halted.
The glitch was the latest incident to raise questions about the dangers of trading via machine, following a sudden plunge in stocks in May 2010 that came to be known as the “flash crash” and the glitch-plagued initial public offering of Facebook last year.
Nasdaq said it wouldn’t be canceling any open orders, but that customers could cancel orders if they wanted to.
The days of stock brokers in colorful jackets, roaming the floor of the stock exchange, are fading. Now, powerful computer programs dominate trading by sifting through reams of data and executing trades in fractions of a second. That makes trading faster and, arguably, more efficient. But it also introduces more possibilities for errors that can jolt the entire market.
