第一个问题，这里说rebalancing偏离 saa可能性越大 越是要小range约束它 否则会越来越偏离saa 但是momentum这种东西 如果越相信momentum 那么一个资产涨 它日后还会涨 此时这个资产就会相比于其他资产涨得越来越多 越来越偏离saa 此时为什么又是wider range呢？ 第二个问题，transaction cost和tax增大 也增加range是怎么解释的？

官网题衍生23题，汇率104.15哪来了？ The data she uses for her assessment show that the US bonds pay 1.75% and Japanese bonds pay –0.40% annualized. She plans to fully hedge the currency risk. The YEN/USD spot rate is 106.85, the one-year YEN/USD forward rate is 106.12, and the one-year YEN/USD cross currency swap basis is –0.63.A is correct. Stuyvesant can sell US$10,000 converted at a spot rate of 106.85 to invest proceeds of ¥1,068,500 at –0.40%. After one year, the Japanese bonds are sold (1,068,500 × 0.9960 = 1,064,226.00) and converted at the forward rate of 104.15, for proceeds of US$10,218.20. The fund has earned 10,218.20/10,000 – 1 = 2.18%. The 2.18% yield is higher than the 1.75% she could have earned in US Treasury bills. The difference is due to the basis given a high demand for US dollars.

Q12，为什么不能选25%，value越大越好

原版书R22的example12的第三问和第四问，一个问期初一个问期末的tax consequences，这个看了解析也听了课程讲解，不是很理解这两个问题的区别。资本利得税这些不都是在期末才会发生么？我看解释说premium的tax也不是在期初付吧？这两道题麻烦老师再解释一下

老师好，这里为什么是D10/D5，为什么不是D5/D10？ 谢谢老师

老师好，R14经典题-active portfolio manager， 问当20yr YTM steeper 0.20% inscreasing时，为什么 Δspread是正的0.4%，为什么不是负的呢？现在国债收益率上升了， 国债收益和公司债收益率的spread不应该narrow了吗？ 我选的B：0.4%， 谢谢老师

L3V3 P270 EXAMPLE 8. In the exam, is the highlighted sentence well enough to get a full mark for this question?

If an investor want to choose stocks under growth approach, should he evaluate the YoY growth for revenue or net income? Is there any difference between these two?

L3V3 p239. In Example B, company C's forward P/E is 2.2, which is absolutely and relatively low compared to other companies. (1) why should not this stock be a good candidate under the relative valuation approach？ （2）The solution said it's a good candidate under the deep-value approach. Through definition, deep-value approach chooses low P/B company and company under financial distress. How can I tell the P/B is low and it is under financial distress?
