二是优化停牌制度设计。停牌的核心意义不仅在于保障所有投资者公平获取信息，更应包括排除人 为制造的不确定性对市场的干扰。投资本就伴随不确定性风险，但并购重组能否通过审批、最终能否落 地也存在重大不确定性，此时贸然复牌可能危及信息弱势投资者的合法权益。因此，在特定场景下，停 牌对防范欺诈、保护投资者利益的作用，应优先于复牌保障交易权的作用。 三是严格重大事项运作与内幕交易的挂钩机制。可明确规定，若相关主体（无论性质与类型）因重 大事项涉及内幕交易、市场操纵，被证券监管部门立案调查或司法机关立案侦查，对于尚未受理的重大 事项申请，交易所应不予受理；对于已受理的，交易所应暂停审核，证监会应暂停注册。有关主体若想 借运作重大事项之机实施内幕交易、市场操纵，将导致重大事项被迫终止，结果是搬起石头砸自己的 脚。 四是多措并举抑制非理性炒作。可在相应板块探索取消涨跌停板制度，实施与新股上市前五天类似 的交易机制。鼓励媒体与研究人员对二级市场的异常波动、异常交易行为发挥监督作用，及时提出质 疑。对于明显偏离公司基本面的股价波动，交易所可组织专业机构开展估值分析和风险提示，引导市场 理性定价。同时，对频繁发生异常交易的账户，可采 ...
