总的来说A股牛短熊长的原因是投机性过强，又没有做空机制，在市场行情好的时候，使劲的吹泡沫，股价上涨速度快，上涨周期短。泡沫一破就需要时间来修复透支的涨幅，具体原因可以参考以下3 点：

1、监管不足。A 股市场信息披露的真实性、完整性和及时性不够，上市公司财务造假、内幕交易等行为频频发生，使得投资者对A股价值投资没有信心，投机炒作之风盛行。

2、投资者结构以散户为主，机构行为散户化。散户投资者的心态往往以投机为主，而很多机构行为特征也趋向散户化，追涨杀跌，价值投资理念缺乏。

3、上市与退市制度问题。过去A股上市资源稀缺，上市即被炒作到达巅峰，后面就只能一路割韭菜。而且缺少退市机制，不能形成良好的优胜劣汰。
