I just watched the full lecture so you can DISREGARD my previous comment

i applied this formula on excel sheet and the result coming out is 2204 instead of 4750.

2,000^2 = 4,000,000 (not 400,000)

yes.. i didn’t notice that..and may be there is a printing mistake on the note.. 400000 is written there…

You are correct – thanks. I will have it corrected.
However I think (hope!) that I show the correct figures in the lecture 🙂

Hello, I was able to work out the answer based on your comments. Please humor me as this aspect of math has never been my strong point.
I don’t get the rationale behind ‘2,000^2’ for the daily deviation. Explain this to me like you would a ‘5 year old’

The formula has the variance in it, and the variance is the square of the standard deviation. You cannot be tested on the rationale, but if you want to know more about the variance then watch the Paper MA (was Paper F2) lectures on statistics.

Could you please explain how did you work out the answer for Example 3 chapter 6. For the formulae Spread, I did not how did you do to get to to: 14,250? Thank you.

I am a bit puzzled as to which bit of the calculation you are not clear about, because I do go through the workings in the lecture and otherwise it is just calculator work.
(I assume you are clear that taking something to the power of 1/3 is another way of writing that it is the third root of what is in the brackets, and obviously for that bit you need to be using a scientific calculator.)

Thank you Sir, I got it.

Sir, why did you use the daily interest rate in the formula?

The calculations are as follows: (a) upper limit (b) lower limit (c) spread (d) return point
The spread is needed to calculate the return point and the upper limit

I don’t really know why you have written this 🙂
The calculations needed depend what information is given in the question. If you look at questions on this in your Revision Kit then you will see what I mean.

Okay sir noted. I did that just to recall what I learnt from your presentation.
