    YouTube T5-08: Convexity and risk premium impacts on shape of term structure

    In this video, I'm going to try to illustrate all of the important ideas that are in Tuckman's Chapter 8: The Evolution of Short Rates and the Shape of the Term Structure. This chapter discusses the shape of the term structure and the key influences on the shape of the spot rate term structure...

    YouTube T4-42: Fixed Income: Duration and Convexity Summary

    In this playlist, David has already recorded at least ten videos on duration and convexity which are the two most common measures of single-factor interest rate risk. So, in this video, we wrap it up in one simple explanation that tries to illustrate both duration and convexity and how we apply...

    YouTube T4-38: Fixed Income: Duration plus convexity to approximate bond price change

    Duration plus a convexity adjustment is a good estimate (approximation) of the bond's price change. We can express this change in percentage terms(%) as given by ΔP/P = -D*Δy + 0.5*C*(Δy)^2; or we can express this in dollar terms ($) as given by ΔP =∂P/∂y*Δy + 0.5*∂^2P/∂y^2*(Δy)^2.

    Convexity and Volatility

    Hi everyone, It's my first time posting but I've been reading the forums since I enrolled for the FRM part I more than a year ago and I wanted, before anything else, to thank you all, particularly David, for all the help I've gotten from such a knowledgeable and supportive community while...

    The price sensitivity of bonds is measured using convexity, duration..

    Please, could you anyone explain me why the convexity increase at an increasing rate as duration increase. I think that the duration should be decrease at an increasing rate. Best regards

    Convexity and V+ / V-

    Hello, I am trying to work on convexity and duration exercises but every time I need the V+ and V- of a bond for my formulas and can't find how to calculate them. Here's an example: I have a bond 9% Coupon. 20 year 6% YTM At 134.622 And a 20bp change in Yield. The convexity formula asks me...

    P1.T3.714. Duration, modified duration and dollar duration (Hull Chapter 4)

    Learning objectives: Calculate the duration, modified duration, and dollar duration of a bond. Evaluate the limitations of duration and explain how convexity addresses some of them. Questions 714.1. A very risky two-year bond with a face value of $100.00 pays a semi-annual coupon of 18.0% and...

    Short convexity/ gamma

    Just thought I would like to share how you actually loose money regardless of the direction of the underlying when you are short gamma (or convexity) by shorting an option. ∆a be the underlying shares (or bonds whatever) we know convexity as ∆a+ 1/2 Г a^2 Thus, our net position will be ∆a -...
