正大国际讲解道琼斯工业指数到底是什么?
2022-04-23 09:51:00 【saberpet】
道琼斯工业指数(DJIA)是由Charles H. Dow和Edward Jones创立于1896年,历史相当悠久的一项股价指数
所谓指数指的就是透过一个数字就能了解整个市场的变化,股价指数的计算就是将整个市场许多公司的股价表现反映到一个数字上。
那个年代是工业革命后一段时间,火车、汽车产业正刚开始崛起的时候,当时重要的股票也都属于工业类的股票,也因此它名称中有「工业(Industrial)」两个字。
但事实上到今天,它的成分股大部分都已与重工业不再相关,道琼工业指数的成分股包含30家在纽约证券交易所(NYSE)和纳斯达克交易的大型上市公司的指数。
比道琼工业指数更早的一档叫做道琼交通平均指数(Dow Jones Transportation Average,DJT),成分股包含20档运输类股,在百年以前那个年代的龙头产业也是铁路运输业,当然到今天就只是众多产业的其中之一而已。
如果你在这行做得久 可以自己开主账户去招商或者自己操作 成本较低saberpet
