Convexity (finance)

In mathematical finance, convexity refers to non-linearities in a financial model. In other words, if the price of an underlying variable changes, the price of an output does not change linearly, but depends on the second derivative (or, loosely speaking, higher-order terms) of the modeling function. Geometrically, the model is no longer flat but curved, and the degree of curvature is called the convexity. (Wikipedia).

Fixed income: Effective Convexity (FRM T4-37)

Effective convexity approximates modified convexity (just as effective duration approximates modified duration). Mathematically, convexity is a function of the bond's second derivative with respect to yield: convexity = 1/P*∂^2P/∂y^2. Convexity is illustrated by the curvature (i.e., non-li

Convexity and The Principle of Duality

A gentle and visual introduction to the topic of Convex Optimization (part 2/3). In this video, we give the definition of convex sets, convex functions, and convex optimization problems. We also present a beautiful and extremely useful notion in convexity optimization, which is the princ

What is the difference between convex and concave

👉 Learn about polygons and how to classify them. A polygon is a plane shape bounded by a finite chain of straight lines. A polygon can be concave or convex and it can also be regular or irregular. A concave polygon is a polygon in which at least one of its interior angles is greater than 1

Bond convexity

Just as (Macaulay) duration is weighted average maturity of bond, convexity is weighted average of maturity-squares of a bond (where weights are PV of bond cash flows). Dollar convexity is also the second derivative (d^2P/dy^2); i.e., the rate of change of dollar duration. Note: the corre

Fixed Income: Duration and Convexity Summary (FRM T4-42)

In this playlist, I've 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

Abstract : Some questions in mathematics are not answered for quite some time, but just sidestepped. One of those questions is the following: What is the quantile of a multi-dimensional random variable? The "sidestepping" in this case produced so-called depth functions and depth regions, a

How the portfolio possibilities curve (PPC) illustrates the benefit of diversification (FRM T1-7)

When correlations are imperfect, diversification benefits are possible. The portfolio possibilities curve illustrates this and it contains two notable points: the minimum variance portfolio (MVP) and the optimal portfolio (with the highest Sharpe ratio). At the end, I summarize four featur
