More convex vs less convex

Is higher or lower convexity better?
A bond with more convexity will offer you more upside if rates decrease, while promising less downside if rates increase.
While a par bond has a price of $1,000, the 10% bond will have a price that is $59.75 lower, or $940.25, match- ing the price we calculated above..
What does greater convexity mean?
Understanding Convexity
In the example figure shown below, Bond A has a higher convexity than Bond B, which indicates that all else being equal, Bond A will always have a higher price than Bond B as interest rates rise or fall.

As interest rates fall, bond prices rise..
What does less convex mean?
Less convex means less power or more focal length.
If the lens is split into two half plano convex lenses then then each piece has half the power of the original one.
Also, we make a lens using greater radius, then again it has less power._{Mar 20, 2015}.
What is more convex vs less convex?
The more convex (or thicker) the lens, the more severely the light rays are bent and the shorter the focal length (conversely, the thinner the lens the longer the focal length).
Different focal lengths create different kinds of image effects..
Which is more convex lens vs less convex lens?
A thick convex lens has more power than a thin convex lens because it has greater curvature or lesser focal length than a thin lens.
A thick convex lens has greater curvature or lesser focal length, whereas a thin convex lens has lesser curvature or greater focal length..
A bond is said to have positive convexity if duration rises as the yield declines.
A bond with positive convexity will have larger price increases due to a decline in yields than price declines due to an increase in yields.
A convex lens makes objects look larger and farther away.
Convex lenses correct farsightedness.
A concave lens makes objects look smaller and closer.
Convex lenses are used in eyeglasses for correcting farsightedness, where the distance between the eye's lens and retina is too short, as a result of which the focal point lies behind the retina.
Eyeglasses with convex lenses increase refraction, and accordingly reduce the focal length.

Convexity measures the relationship between bond prices and bond yields, which shows how a bond's duration changes with interest rates.Understanding ConvexityBond DurationConvexity and RiskExample

What Is Convexity?

Convexity is apparent in the relationship between bond prices and bond yields. Convexity is the curvature in the relationship between bond prices and interes…

Understanding Convexity

Convexity demonstrates how the duration of a bond changes as the interest rate changes. Portfolio managers will use convexity as a risk-management tool, to meas…

Bond Duration

Bond durationmeasures the change in a bond's price when interest rates fluctuate. If the duration of a bond is high, it means the bond's price will mov…

Convexity and Risk

Convexity builds on the concept of duration by measuring the sensitivity of the duration of a bond as yields change. Convexity is a better measure of interest r…

Example of Convexity

A bond issuer, XYZ Corporation, has two bonds on the market: Bond A and Bond B. Both bonds have a face value of $100,000 and a coupon rate of 5%. Bond A…

Negative and Positive Convexity

If a bond's duration increases as yields increase, the bond is said to have negative convexity. The bond price will decline by a greater rate with a rise in yields …

The Bottom Line

Convexity is a measure of the curvature of its duration or the relationship between bond prices and yields. It describes how the duration of a bond changes in re…

Are NE functions convex or concave?

ne functions: f(x) = aT x + b (for any a 2 Rn; b 2 R)

They are convex, but not strictly convex; they are also concave: ne functions are the only functions that are both convex and concave

Some quadratic functions: f(x) = xT Qx + cT x + d

{ Convex if and only if Q 0

{ Strictly convex if and only if Q 0

Does a convex function have a unique minimum?

A strictly convex function will always take a unique minimum

For a convex function which is not strictly convex the minimum needs not to be unique

For example, f(x) f ( x) above takes its minimum everywhere between -4 and 4

Hence, the minimum is not unique

For g(x) =x2 g ( x) = x 2, however, there is only one unique minimum at x = 0 x = 0

What happens if a function is strictly convex?

geometrically, if it's strictly convex, it cannot have line segments on its graph, so in a sense it always "bends"

While, if you do away the "strict", then the function may become linear at some part of its domain

f(λx + (1 − λ)y) ≤ λf(x) + (1 − λ)f(y) f ( λ x + ( 1 − λ) y) ≤ λ f ( x) + ( 1 − λ) f ( y)
