为努力防止股市大幅下跌，上海证券交易所于周六发布通知限制大股东减持比例。
The Shanghai bourse issued a circular to cap the share sell-off rate for large shareholders on Saturday, in an effort to subdue the market's free fall.
通知明确表示，持股5%(含)以上的上市公司大股东任意连续3个月内通过证券交易所集中竞价交易减持股份的总数，不得超过公司股份总数的1%。
The Shanghai Stock Exchange forbids major shareholders with stakes of 5% or above from selling more than 1% of a listed company's share capital through the stock exchange's centralist bidding system every three months.
这一限制是因为在周四新引入了熔断机制后，仅半小时内股票就暴跌了百分之7而宣布的。该机制自1月1日起，在一周内两次触发。
The restriction was announced as stocks plummeted 7 percent half an hour into trade on Thursday, triggering a newly introduced circuit breaker. The mechanism in effect on Jan. 1 was triggered twice in the week.
自去年起，中国证监会通过对投机交易罚款等措施，对短期内的大额减持抛售股票行为加强了监管。
The China Securities Regulatory Commission has tightened control on short-term big share sales since last year by imposing fines on profiteering trading.
证监会还要求大股东减持需要提前15个交易日披露。
It has ordered major shareholders to file plans 15 trading days in advance of sales.
在本周一(11日)，股市继续走低，约有千只股票跌幅至日限10%。
Stocks continued to edge down on Monday, with about a thousand stocks tumbling by the daily limit of 10%.
