(85,373 posts)20. 3 Years Later: Learning to Live With Flash Crashes
http://www.cnbc.com/id/100709978
Rather than being simply a one-off event that Wall Street could dismiss as an aberration, the first Flash Crash now looks like it was just the opening warning shot. In 20 breathtaking minutes that happened three years ago MAY 6TH, the stock market saw the Dow Jones Industrial Average lose nearly 1,000 points, only to rebound just as quickly. Academics and market experts have pondered the cause and effect of the event since, and market circuit breakers have been used to good effect at least to rein in similar events before they get out of control. But indeed there have been numerous subsequent flash crashesnone as dramatic as the initial one but each a reminder that a certain dynamic has been changed in the stock market, likely on a permanent basis.
What makes the first Flash Crash especially troubling is the lack of concrete findings about the cause. Most of the blame has been narrowed to irregular trading over a futures contract related to the Standard & Poor's 500the "e-mini" to be specific. Regulators moved to install trip mechanisms that shut down trading if similar patterns repeat, and for the most part they have worked. But it's clear the machines have taken over, and with that will come mistakes that only machines can make.
Most recently, the market endured a flash crash social media-style. An April 23 post on The Associated Press' Twitter feed indicated that two explosions had occurred in the White House, injuring President Barack Obama. The report triggered a brief but aggressive market sell-off that reversed itself when it quickly came to light that the AP Twitter feed had been hacked and the post was a hoax....Over the years, many companies have seen shares plunge and spike due to little else than the vagaries of the electronic high-speed trading that has come to dominate the market. The cumulative result: Little in terms of actual stock value, but much in terms of market credibility
Indeed, while there has been drop in market trading volume, simply sitting out of the market has been an expensive form of protest. Despite all the hoopla over the initial crash and its smaller cousins, the Dow is up a staggering 42 percent since the initial event. And for how scary it may have been, the term "flash crash" seems much more significant to market insiders than it does the typical investor.

"Flash crashes will occur and it will happen again," said Todd Schoenberger, managing director at LandColt Capital. "If you are a retail investor, you're always going to look at the market with a cautious eye because you're going to be nervous over whether Wall Street has your best interests in mind."

"You have 60 percent of America invested in the market either directly or through 401(k) or pension plans. That means six of every 10 are vulnerable to a flash crash, and the only way to reduce or eliminate that risk is just not to be invested at all," Schoenberger said. "And that's not an option, either."

"The market's moved past it. The Flash Crash came and went so quickly that, other than being a news event, most retail clients would not have even noticed it," said Mitchell Goldberg, president of ClientFirst Strategy. "It was kind of like watching a boxing match," Goldberg said. "You get set, you get your pretzels and your beverage, you put your beverage down on the floor, you look up and the fight's over."
