Thank you so much for the amazing content
Thank you sir, your course on statistics is much better than the explanation of Kaplan
Thanks and welcome
Thank you ift team you are really helping me in understanding the lecture not just memorizing!
I'm preparing for CFA Level 1 exam in Feb, it will be enough to study on your channel the lectures to pass the test?

Thanks for providing such great content and explanation for free!
A small doubt, for the practice question at 7:09, the question under the table is to find "the portfolio which minimizes the probability of investor's portfolio falling BELOW 100K.
So accordingly, the required return should be 0% instead of 4% in my opinion.
If the required return is 4k, shouldn't the question be written in a different way?
Please correct me if I'm wrong, Thanks!
Thank you
Thank you!!!
You're welcome!

Thanks :)
Hi. Really appreciate your videos. Subscribed earlier. Was wondering if you cover continuously compounded return (CCR) and how to solve natural log with the calculator somewhere?thx

Need help with Schweser Notes- Pg.240 Q.2> For a continuous random variable X, the probability of any single value of X is> a. One b. Zero . c. Determined by the CDF. Although the answer is zero, I didnt understand the rationale behind the solution. Thanks in advance! :)
Hi there and thanks for your comments. However we cannot comment on the Notes or questions from others. We can help you with curriculum issues or any IFT materials. Have you tried IFT Notes? Here is a link to free Study Notes for Level I : Ethics and Quant >>> ift.world/freestuff/#notes
Since a continuous RV can take infinitely large values, the prob. of any one of them occuring would be 1/infinity which is zero.
Thank you very much
You are welcome
Are log normal distribution and monte carlo simulation important in the Level 1? Thank you
yes, since these topics are covered in the learning outcome.

Hello, isn't it possible to consider that by the end of the year, for the practice question of 7:09,the minimum level is to have a -96% return? This would be Return of (4k/100k-1) = 4%-1= -96%, considering that at the end of the 1y investment he would also receive the 100k initial position., therefore the answer would be A as SF_A=10.1= (5%-(-96%))/10% [SF_B=8, SF_C=6.24]. Just curious about the way in which I got it before checking your answer.
No. On investment of 100,000, the investor requires a return of 4000, i.e. 4000 / 100,000 = 4%.

@@IFT-CFA I have a quite similar question. The question under the table is to find "the portfolio which minimizes the probability of investor's portfolio falling below 100k. So I have assumed that the required return is 0%. If the required return is 4k, shouldn't the question be written in a different way?
@@felipecunha6287 Agree. I also have the same question
I want to ask about the difference between the Sharp ratio and Safety-first ratio since these two have a very similar equation. Always thanks for your good lectures!
Dear Taewan,
The Sharpe ratio uses the risk free rate to calculate the excess return, whereas, the Roy's Safety First ratio uses the investors required rate of return to calculate the excess return.
