问题 单项选择题

从根本上决定股票价格长期变动趋势的是( )。

A.财政政策

B.货币政策

C.经济景气

D.股民心理

答案

参考答案:C

解析: 股票在交易市场上作为交易对象,同商品一样,有自己的市场行情和市场价格。由于股票价格要受到诸如公司经营状况、供求关系、银行利率、大众心理等多种因素的影响,具波动有很大的不确定性。影响股票价格的因素除了以上这些外,还有很多,例如:股市人气的高低、庄家对个股的控盘程度,国家政策对股市的调控等,其实,股价或股指的高低是各种因素影响的综合结果,并不是单个因素影响的结果。 从长期和根本上来看,一个国家的经济发展水平和经济周期决定着该国股票市场的基本走势。在经济发展的上升时期,企业经济状况良好,盈余较多,其股票价格处于上升态势。反之,在经济发展的不景气时期,由于投资和消费下降,企业销售不畅,收入锐减,盈余较少甚至亏损,其股票价格会不断下跌。因此,股票市场实际上是整个国民经济发展的“晴雨表”。故答案为C。
