convexity - Investment & Finance Definition
bond or note, a measure of the way duration and prices change when interest
rates change, as represented in the curvature of the price-yield relationship.
A bond or note has a positive convexity if the instrument’s value increases at
least as much as duration indicates when rates drop, and decreases less than
duration indicates when rates rise. Investors want positive convexity because
it makes a bond more valuable after a price change than its duration value
options, a measure of the way the value of the position changes in response to
the change in the volatility or price of the underlying instrument. An option
with positive convexity holds or increases its value more than delta (the
change in the price of the option with respect to a one-dollar change in the
price of the underlying asset) would predict when volatility increases or when
prices change by a large percentage.
The males are usually more brilliantly coloured than the females, and guard the eggs, which are often placed in a sort of nest made of the shell of some bivalve or of the carapace of a crab, with the convexity turned upwards and FIG.
Then when once across the stream it was discovered that unlike the normal slopes in the district the hillside in front of them showed a slight convexity under cover of which they were able to re-form in regular order.
West of this line the rocks are chiefly Tertiary and Quaternary; east of it they are mostly Palaeozoic or gneissic. In the western mountain ranges the beds are thrown into a series of folds which form a gentle curve running from south to north with its convexity facing westward.
When this is the case the gathering is carried to a block or half-open mould in which it is rolled and blown until it acquires, roughly, the shape of a hemisphere, the flat side being towards the pipe and the convexity away from it; the diameter of this hemisphere is so regulated as to be approximately that of the cylinder which is next to be formed of the viscous mass.
Where the water has little motion it is almost straight; where the current is considerable it is curved, with its convexity towards the stream.
