Bullets/Barbells and convexity
I’ve noticed in the book they say that barbell has more convexity but don’t explain why. I understand barbells perform better when yield is flattening.
I’ve also can see that the barbell is shown to be more convex but they don’t seem to give an explanation as well. They SHOW in exhibit 9 and 1 that a barbell has more convexity but it’s not explained in layman’s terms.
Can somebody explain to me why it has more convexity?
