How to calcualte the splied stock?

In the price-weighted index of index construction methods, how to calcualte the splied stock?  

As it showed in the PPT, if $100/share stock was splited as $50/share, then the denominator becomes 1+1+100? Why not instead of 1+1+1+1?

And also whats the meaning of *3?

Could you explain the entire formular in a much simple way? or examples?

嗨,努力学习的PZer你好:


Price Weighting是假设所有股票都买相同数量,分子是所有股票股价之和,分母是股数之和。譬如index里面有ABC三只股票,股价分别为5,10,15元。B股票1股拆为2股,拆股后,股价瞬时变为5元。拆股前,index=(5+10+15)/3=10,分拆后index=(5+5+5+15)/4=7.5。所以是分母Denominator发生了变化。

虽然现在很辛苦,但努力过的感觉真的很好,加油!
