"volatility confidence interval的" 给了vol的daily 值,给了一年working day 260, 要算最后95%的confidence interval, 这一题有没有人想起来怎么做的?
我算的方法比较奇怪,因为我觉得vol应该和interest rate 是相乘 [expected interest rate = current int * (1+vol%) ]不是相加的关系,最后选的interval最大的那个,一直很疑惑这样子解对不对?

这道题我临时想了这个方法算的:因为0.7%是每天的变化,所以是Continuous的,Continously compounded daily change (Ic) = Ln(1+0.7%)。然后用Current int*(1+1.96*e^Ic*260)来算。倒是凑出个答案来,不知道对不。。。

黄金的题目,前两问都是问gain or loss吧?如果是的话,就不要考虑期权费用本身价格的变化了。一级里面讲的g/l,不就是payoff加上原来期权的费用么?

postion是short call+gold inventary+gain on short=gold invertary×开始price

后来条件变了,position就变了啊,fair value hedge,derivative要mark to market的,不是卖掉就没事了

请问大家是否记得这题

 

有无人记得某个地图上找不到名字的两个国家(我觉得其实在写中国和美国关系), 有题问policy discourage immigration, as well as one family have two children.  问 对gdp, real wage, 还是 gdp/labor 有大影响? 应该选什么

糊涂了。

from wiki:

Economies of scope
are conceptually similar to economies of scale. Whereas economies of scale primarily refer to efficiencies associated with supply-side changes, such as increasing or decreasing the scale of production
economies of scope refer to efficiencies primarily associated with demand-side changes, such as increasing or decreasing the scope of marketing and distribution, of different types of products.

我觉得Economies of scope 是对的,因为合并后两个牌子的啤酒都可以打入对方的市场了,扩大了整个市场,而且还可能有一些其他的synergy。而learn curve,刚合并后肯定造成一开始效率的缓慢的啊,所以是negative的,我是这么想的

prop trading 是指公司自营盘交易,这几道ethics我和你选的都一样

第一题问得是关于material nonpublic info是不是Suffficent,我和你一样选了不能有效防止自由流动


我觉得这家公司的规定挺严谨的,分析和投行任何交流必须通过compliance,不管个人认为是否构成material non-public information。

感觉大家交流来交流去,其实很多题目还是拿不准的,特别是定性的题目.

 

很难讲谁是标准答案呀,就等CFA协会来评判了.

每年看Clawback,虽然PE看长期回报,但是不是PE企业的每个投资目标都是同一年exit的,所以还是需要每年clawback,而且按deal by deal评估
