以下是引用japhyhan在2007-12-3 9:35:00的发言: 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. [em01] |
