price-weighted的股票拆分不改变index吧

Maybe I can't agree on this.

Notes stated that price-weighted index tends to be baised downward as large growth companies may issue stock-split which downwards price-weighted index.

Also, after stock-split, stock prices decrease which leads to lower price-weighted index.

Welcome for any comment.

楼上的太牛了。楼上的楼上，我同意你的思路，偶也是这样分析滴，但是回忆了一下，具体的计算我似乎还是做错了。

上海考的，感觉比Note6看起来要容易得多，做得也快，但是有很多题不是很有把握，都有一些模棱两可的感觉。

求证一下那道关于regression的题：

Intercept=1  Corralation coefficient=0.56

后面的选项好像都不对阿：一个说如果market return=0, stock return=1.31,应该是1

                        一个说Coefficient of determination=0.78,应该是0.31

                        一个说这个stock的market risk小于market，这个也不对啊

                        一个说能解释的variation大于一半，但也是错的阿，因为R2小于0.5阿。

我抓瞎了好久，只好选了最后那个。

祝大家一起过关！

philip curve那题短期是不是有个假设不变的？ 只是描述价格水平和失业率的关系啊

index那题我记得很清楚题目是说：immediately after split, 那应该是不变的，但是因为除权了，所以以后的增长是对指数的影响变小了，downward bias是指这层意思吧

第三个是对的 beta<1

Sorry, I cann't agree with you too.

The Shwester notes fail to include a concept called 'divisor'.

To get the price-weighted index, sum up the prices of the stocks in the index and then divide that number by a divisor. Remember, this divisor is not simply the number of different stocks included in the index and should be changded to maintain the continuity of the index bafore and after a stock split.  How can you emagine DJI changes a lot just because a stock split of a single stock?

This content is in the Reading Material 56, not the notes.

hehe, so i chose the unchanged answer.
