美证交会将于11月决定是否实施股价涨跌停限制

摘要:美国证券监管当局将多花上两个月时间决定是否采取“涨停-跌停”限制,
美国证券交易委员会(SEC)发布文件指出,11月28日将决定是否批准交易所4月所提出的
这项计划。
汇通网9月29日讯——据媒体周三(9月28日)报道称,美国证券监管当局将多花上两
个月时间决定是否采取“涨停-跌停”限制,以期在剧烈波动的时刻减慢交易速度,比
如像去年所发生的“闪跌”现象。
美国证券交易委员会(SEC)发布文件指出,11月28日将决定是否批准交易所4月所提
出的这项计划。
公众评论期将于9月29日截止,但SEC表示,在采取行动前需要更多时间考虑这些评
论。
涨跌停计划将为个股设定浮动的价格上下限,为因应2010年5月6日道琼工业指数在
数分钟内崩跌近700点的“闪跌”现象所采取的部分行动。
在股价崩跌后不久,即启动了所谓的熔断机制(circuit breakers)暂停个股交易。
涨跌停限制将搭配这些熔断机制,以及SEC计划调整的以指数为主的熔断机制。 | b*****n 发帖数: 221 | | y*****l 发帖数: 5997 | 3 他们是害怕大跌,提前做好防护措施。
现在还不会崩盘,我估计牛牛还有至少一周的时间出逃,逢高减仓。 | f******e 发帖数: 6488 | 4 呵呵
他們的限制和天朝不一樣吧
主要是針對大盤,而不是個股

个股是5分钟内涨跌不能超过10%,天朝是当天10%,不一样。
Circuit Breakers and Other Market Volatility Procedures
The major securities and futures exchanges have procedures for coordinated
market-wide trading halts if a severe market price decline reaches levels
that may exhaust market liquidity. These procedures, known as circuit
breakers, may halt trading temporarily or, under extreme circumstances,
close the markets before the normal close of the trading session.
The circuit breakers provide for market-wide trading halts during a severe
market decline as measured by a single day decrease in the Dow Jones
Industrial Average (DJIA). There are three circuit breaker thresholds—10%,
20%, and 30%—set by the markets at point levels that are calculated at the
beginning of each quarter. The formulas for these thresholds are set forth
in the New York Stock Exchange (NYSE) Rule 80B.
For example, for the fourth quarter of 2010, the Level One (10%) circuit
breaker is set at 1,050 points, the Level Two (20%) circuit breaker at 2,100
points, and the Level Three (30%) circuit breaker at 3,150 points. You can
find the current thresholds for market-wide circuit breakers by visiting the
NYSE's Circuit Breakers webpage.
In addition to market-wide circuit breakers, the SEC approved market rules
on a trial or “pilot” basis in 2010 allowing circuit breaker pauses for
certain individual securities whose prices move 10% or more in a five-minute
period. These circuit breaker pauses apply to stocks in the S&P 500 Index,
Russell 1000 Index, and several hundred exchange-traded products, and halt
trading in the applicable security in all U.S. markets for five minutes. U.S
. exchanges and the Financial Industry Regulatory Authority (FINRA) proposed
the rules in response to unusually volatile trading on May 6, 2010, that
affected some stocks but was not broad enough to trigger the existing market
-wide circuit breakers. This pilot is due to expire on January 31, 2012
unless exchanges and FINRA propose to extend the trial period or request
permanent approval of the rules.

Bulletin on that topic.
