Great video Fabian! With a numerical description, I now have a very clear understanding as to how price and reinvestment risks are offsetting each other. Great content.
Thanks Fabian this video is really great! For those who are also struggle with Fixed Income like me, this video is very useful for the CFA level 3 (2022-2023) curriculum book 2 Reading 12 cf exhibit 5.
Great video@@FabianMoa, I've liked and subscribed as well. What about loan portfolio with different coupon frequencies? are we going to calculate cashflows using smallest frequency period?
A lot of the examples I see are with rounded time periods or years to maturity, what is the best way to adjust for fractional periods such as 14.58 years or more real world scenarios?
In summary, for immunization, the money duration (modified duration x market value) of the assets must be equal to or exceed the money duration of the liabilities. For a single liability, the convexity of assets must be minimized. For multiple liabilities, the convexity of assets have to exceed the convexity of the liabilities.
Hey Fabian - Question on the last bit. Can I say if the liability is immunized (liability is due at ~6.008 years) and the portfolio is held to Macaulay-duration maturity, then no matter where the yield goes (ups or downs), the portfolio can still cover my liability. It's just the fact that, in your example, the portfolio value does change upon yield changes got me thinking if this portfolio still has the ability to immunize the liability? thanks!
"Can I say if the liability is immunized (liability is due at ~6.008 years) and the portfolio is held to Macaulay-duration maturity, then no matter where the yield goes (ups or downs), the portfolio can still cover my liability" - Yes "It's just the fact that, in your example, the portfolio value does change upon yield changes got me thinking if this portfolio still has the ability to immunize the liability" - You can observe that regardless whether there was an upward or downward shift, the value of the portfolio was quite similar (under the two scenarios). And the values under both scenarios are higher than if there was no change in yield at all (so that creates a buffer for covering the liability too).

So excellent and learnt financial modeling at the same time....
Thanks Fabian this video is really great!

I'm preparing the Exam, the video is very helpful ,thank you!
Thank you. Excellent illustration.
This video is so helpful for me. Thank you a lot!
Great job as always! Very much appreciated!
Thank you! Cheers!
Great explanation
Awesome explanation! Quick question at 22:27. I think you meant assuming the YTM increases by 1% and not cash flow yield?
The cash flow yield is the YTM of the portfolio
Love your videos Fabian. For annual coupon bonds, how would you calculate the dispersion and convexity?
You would do it the same way as in the video but the periods 1, 2, 3, ... will be in annual terms.
Great video@@FabianMoa, I've liked and subscribed as well. What about loan portfolio with different coupon frequencies? are we going to calculate cashflows using smallest frequency period?
Using daily cashflows would provide more accuracy
Hi While calculating modified duration you are already using annualized MacDur. Why did you have to divide by two then?
A lot of the examples I see are with rounded time periods or years to maturity, what is the best way to adjust for fractional periods such as 14.58 years or more real world scenarios?
fabian can u share the excel sheet template so we work along with the video as well
Thanks Fabian for the video. May I ask if you could explain how we can use both duration and convexity in immunization, please?
In summary, for immunization, the money duration (modified duration x market value) of the assets must be equal to or exceed the money duration of the liabilities.
For a single liability, the convexity of assets must be minimized.
For multiple liabilities, the convexity of assets have to exceed the convexity of the liabilities.
great video
Thanks!
very helpful
Glad to hear that, Alex!
