针对2015年股灾所表现出的大盘断崖式下跌让投资者躲之不及的特点,以及启用熔断机制失败从而引发更大股灾的事实,本文提出一种应对大盘剧烈波动的新机制——红绿灯机制。红绿灯机制在大盘下跌或上涨达到某个指标时通过限制个股低卖或高买,防止投资者的过度恐慌,从而达到稳定股市和保护投资者的目的。
In response to the fact that the cliff-like decline in 2015 caused investors to hide behind the fact and the fact that the opening of the fuse mechanism failed to trigger a greater stock market crash, a new mechanism to deal with the drastic fluctuations in the broader market is proposed. Traffic light mechanism in the broader market fell or rose to reach an indicator by limiting the individual stocks sold low or buy high, to prevent excessive panic investors, so as to stabilize the stock market and investor protection purposes.
