Dear sir
like to seek your clarification whether we will be tested to calculate VAR figue?
thanksJune 6, 2011 at 11:16 am #82638You could be asked VAR, but I think less likely from this examiner.
August 31, 2011 at 2:14 pm #82639Dear John,
Could you please clarify how the figure [/b]1.65 was derived in the example given in June 2011 Revision. Thank you beforehand.“[/i]A bank has estimated that the expected value of its portfolio in 2 weeks time will be $50M, with a standard deviation of $4.85M. At the 95% confidence level, what is the VaR?”
The answer is: 50M – 1.65 x 4.85M = $42M
November 6, 2011 at 4:49 pm #82640From the normal distribution tables 1.64 standard deviations has a 5% chance of being exceeded.
So there is a 95% chance of being more than the average/expected less 1.64 standard deviations .May 15, 2012 at 3:53 pm #82642This still does not explain it though. Where does the 1.65 for a 5% chance and 2.33 for a 1% chance come from? is is expected that we know this? do we perform a calculation? if so what? it refers to the standard devation table – this does not work for me, unless I am using it wrong? I have searched everywhere for answers and all I get is the same to figures, 1.65 and 2.33 – where do they come from??!! : (
a reply would be mucg appreciated.
thanks vicky
May 26, 2012 at 8:40 pm #82643take your standard normal distribution table and work backward
5%=0.5-0.05=0.45
from tables you get 1.645 for the value of 0.45
i hope it helps you.November 26, 2013 at 2:29 pm #147916thank you so much slobodanm…. you’ve helped me out GREATLY! I almost gave up on this… but your approach has solved it all for me. God Bless you!

I JUST READ THE OTHER DISCUSSIONS REGARDING VAR!
& discovered your detailed explanation regarding 1.64 nd 2.33 valuesTHANK YOU LOADSSSSSSSS!!
🙂November 28, 2013 at 9:40 am #148213Great – you are welcome 🙂
November 28, 2013 at 1:04 pm #148284Hi,
could some one please post that link here. I don’t understand this 1.64 if 5%and 2.33 if 1%
November 28, 2013 at 4:09 pm #148312If you look up 1.64 standard deviations in the normal distribution tables, then you get 0.4495
What this means is the 44.95% (virtually 45%) of all values lie between the average and 1.64 standard deviations away from the average.
Because the distribution is symmetrical, it means that 50% of all value lie below the average.So….it means that 5% (50 – 45) will be below 1.64 standard deviations from the average (or that there is a 5% chance that it will be below this figure).
If you look up 2.33 in the tables and follow the same logic you should find you end up with 1%
November 30, 2013 at 11:48 pm #148727Thank you , for explaining this sir . I have p7 on monday, had been revising that from last 2 days .
Is there any chance you could give us 10-15 questions from Kaplan revision kit that would cover most of the topic on last day.
I am not very confident about swaps, collars, floors, caps i guess that is going to take most of my time last day.
December 1, 2013 at 8:01 am #148765You are welcome.
Concentrate on past questions – especially the section A ones.
Do not spend to much time on the exams from 2009 and 2010 (they were a previous examiner).December 1, 2013 at 8:07 am #148766AnonymousInactive- Topics: 0
