^this as well as the portfolio, 2 asset, etc variance and std dev formulas are probably the hardest ones to remember for me. nice job all from memory!
fra payoff and the options formulas are particularly hard for me to remember.. it'll be a "night before" memorization for me hahaha作者: JGovender 时间: 2011-7-11 18:27
You're forgetting cost of ST borrowing. Difficult to retain but quite important作者: jim8z3 时间: 2011-7-11 18:27
its not that difficult trust me
look keep the point in mind that
ST is per period cost of borrowing devided by net proceeds
Bank loan for 2 months
Net expense= Interest for 2 months + any commitment fee for two months
Net proceeds= Loan amount (as you will be awarded full amount)
Banker's acceptence
Expense= discount for two months
Net proceeds= Amount-discount (what you get initially)
commercial notes
expense: (discount+dealer's commision+backup commision) for two months
Net proceeds= Amount-discount (what you get initially)
its not that difficult i guess
and yes
do remember Inverse floater's return
Payoff=L-R(rate) (correct me if i am wrong)作者: Finalnub 时间: 2011-7-11 18:27

where did you get these formulas from? i dont remember Schweser teaching me formulas for short term borrowing..? Just showed me what the different forms of short term borrowing were.
