我說的是Fall Edition. 我已投書兩次,發現這本有一些關鍵性錯誤, 而出版者也證實是錯誤. 因目前仍有疑問的地方, 我想請問大家有沒有發現除了: http://www.actexmadriver.com/client/client_images/pdfs/ACTEX_FM_Fall07.pdf 以外,還有錯的地方更新: Dear Tiffany: You are correct about the error you reported to us. Thank you very much for bringing them to our attention. As a token of our appreciation for your feedback, we are entering your name in our next drawing for $100 in I.P.A.S.S. points.

Hall Subject: Customer Feedback Form Opinion Form From Website Course: Actex Study Manual Soa Exam FM I found this manual: VeryGood I found the following helpful: Everything is helpful! I found the following problems: The concept on M10-32 and M10-33. Supplemental Exercises #4 Investstor A buys the index at time 0 and sells a 1025 strike call with T=.25. Investor B writes a 1025 strike put and "borrows" x. The two investors have the same payout functions. What is x? To improve manual: I think it should be "lends". Since a zero-coupon bond writer borrows money from a zero-coupon buyer. And the buyer "lends" money to the bond writter. And as the content of the text and the manual itself: Covered Call= payoff[index-call with strike K]=payoff[zero coupon bond for K - put with strike K]=> When we buy a bond, don't we "lend" the money not "borrow"? I thought "borrowing money" is "selling a bond." Maybe I'm confused. Please help! 急需討論Actex FM 2007 FALL Edtion!!!!! 請聯絡我~用我站內的信箱!!! 還有~我目前寫email給Actex: M11-23#6也有些許讓我覺得奇怪的地方, 明明是paylater strategy,卻沒有使用這個rules而有莫名其妙的解答. 請各位指教!!! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 61.224.46.28
