用每车年死亡率就是脑仁有虫。
显然应该用每车事故死亡率。
当然是只考虑被动安全性的前提下。
用exposure除一下每车年死亡率就有意义的多。
IIHS这帮蠢货知道要control for driver的特征，
怎么就不考虑可能影响事故严重程度的变量？
比如事故发生地区（多雪etc）。事故赔付金额。# of vehicle是 per exposure。 etc |

发帖数: 2911 | 9 我反感他们的原因是，学生事先看video自学其实是事倍功半的，而且没人讲解答疑
可能根本就看不懂。一个好的老师，比如我，可以把概念生动形象的讲解清楚。当然
一个烂老师根本就讲不清楚，那是老师的问题。所以说first exposure也要看效率。
至于second exposure，有课堂练习，课堂上老师可以及时给予反馈。有课后作业，做
不出来还有office hour答疑。
另外，那些所谓的新方法，所做的实验就是在比如Harvard选几个课堂，实验一下，然
后宣称结果很好，于是宣称应该推广到全国所有的学校。可惜啊，他们假装不知道普通
公立大学的学生素质（学术背景，智商，学习态度）跟Harvard的学生是不一样的。
另外，就我所知我们学校的情况是，教育系的学生的学术背景和智力水平其实是比较差

trades do so because they want to beat the market. Retail investors do so

发帖数: 1204 | 14 Rebalancing is still needed, not to time the market, but to adjust your
portfolio's equity exposure as you aging.
However, I was surprised by the finding of a recent study which showed that
the optimal equity exposure curve is not what we normally thought a L (with
a declining bottom), but rather a U (with the right side lower, though). |

发帖数: 278 | 15 Index fund不应该用performance 去衡量。需要就买，不需要就不买。
Bogle对international的否定态度不是完全没道理，在他那个年代至今，美国就是不二
的老大，其他经济体跟着它一荣俱荣一损俱损，关联很大，所以他认为只需要有US
market exposure就够了。但今后还是不是这样，就不好说了，我坚信将来经济的活力
就在新兴市场， 如果没有international 会有performance的损失。
另外，vanguard 的大部分international fund都是不hedge currency risk的，加
international fund 就等于加入了currency exposure, 多了一份diversification的
因素。如果你相信美元长期相对其他currency必定走弱, 有一个non-hedged的
international fund会boost performace. |

That said, IEMG (ishare core em etf) tracks MSCI EM IMI index which doesn't
include A-share. ER 0
