这题算组合VAR的时候为什么又不需要乘以weight了？？

为什么100（1+S12）=100（1+S6/2）（1+K/2），这里的K不是合同利息吗？应该用真实利息吧？

A 是不是也没错啊

为啥不选C呢

老师好，关于选项A，我不是很理解。我认为当时间越长的时候，融资者会有更多的时间来进行融资，这样他的融资风险应该是下降的。

课件66页的duration2.733是怎么算出来的？谢谢！

信用风险第5课，第90分钟左右，讲义111页那个表格，A表的显示porfolio A，value大于1000000，那要让B交抵押品，是775000，porfolioB value大于1000000，也要A交抵押品625000，对吧，双边netting一下才是B给A交150000，对吧，是这个意思吗？

信用风险第5课里面53分钟老师举的这个·例子，若b和c之间不存在交易，也可以这样netting？

请问在within asset classes 中，要得到流动性溢价是不是就是买入流动性差的 ，卖出流动性好的？ 比如 买入 off the run 卖出on the run

"The CAPM was revolutionary because it was the first cogent theory to recognize that the risk of an asset was not how that asset behaved in isolation but how that asset moved in relation to other assets and to the market as a whole. Before the CAPM, risk was often thought to be an asset's own volatility. The CAPM said this was irrelevant and that the relevant measure of risk was how the asset covaried with the market portfolio--the beta of the asset." What else does he say is true about the CAPM? A.CAPM is known to be a spectacular failure with respect to its predictive power. B.Neither finance professors nor CFO employ CAPM C. Equilibrium asserts that factors are temporary because arbitrageurs eventually eliminate factors. D. Investors make very different predictions about asset returns, variances and correaltions; equilibrium is theory that says this diversity of beliefs is reconciled via the market price mechanism of supply and demand.请老师解释下这题，谢谢！
