extended disruption

冲刺笔记下P94，variable annuities，用股票抗通胀，股票多了，不应该相关性变小么？

冲刺笔记下P93，prepayment penalties on debt investments，这不是提前还款，duration减小么？不应该减小相关性么？

老师麻烦解答下原版书这个case的solution2

convertable bond

2015真题 B老师看看我红笔圈出来的部分对不对

老师，casebook里有一题：Credit spread will tighten, sell 3 yr AAA corp bond, buy 30 yr AAA corp bond, risk? Spread tighten, long term interest rate could increase. Thus, price increase from spread tightening could be offset by price decrease form yield curve shift. 为什么利差收紧，长期利率上升？谢谢！

2016真题 A有没有显示illusion of control?

老师，所以forced_heirship高于遗嘱，但可以和在community_property里选哪个对我有利我就遵守哪个是吗？

老师好，这个题目不理解为什么选C？
