第十题，我认为a选项，不是期货合约，所以很容易违约啊。bc选项以为不是交易所交易，所以要找对手方啊，感觉没错。

18.应该怎么理解？为什么选a，是买入看涨期权收益无限，损失有限，write 指的是卖出的意思吗，卖出看跌期权收益有限，损失无限，因此综合来看，风险敞口为long对吗，这个理解对吗，不对应该怎么理解，谢谢

16.题目在问什么，考的是什么知识点，为什么选b，解答，谢谢

14.pool investment 不是集合投资的意思吗，跟这个指数有什么关系，解释，谢谢

请问老师，题目没有看懂中文意思。我觉得accrued revenue is record after cash collected anf before revenue is earned吧？所以应该选A吧。可是答案为什么是C？

10.哪里有相关的知识点？还有看不懂，题目和答案，选项，解释，谢谢

这一题为什么选C protective put=long put + long stock=fiduciary call=long call+long bond 怎么推导到C选项的呢

请问老师，这边的9%是怎么来的？

这道题的economic benefits是什么意思？profits的意思？

Comment 2: There is a difference between the pricing and the valuation of forward commitments. Pricing involves determining the appropriate forward commitment price or rate, typically after it has been initiated. Valuation involves determining the appropriate rate of the forward commitment when initiating the contract. 解答， B is correct. Characteristic 2 is incorrect. The conversion factor in a futures contract does not apply to accrued interest. It is a mathematical adjustment to the amount required when settling a futures contract that is supposed to make all eligible bonds equal the same amount—for example, adjust each bond to an equivalent 6% coupon bond. When multiple bonds can be delivered for a particular maturity of a futures contract, a cheapest-to-deliver bond typically emerges after adjusting for the conversion factor. 麻烦老师解释下，谢谢！
