What is betavexity?

Betavexity

Where have you heard about betavexity?

If you’re familiar with carrying out detailed, mathematics based analysis of investments, then there is a high chance that you’re aware of the concept of betavexity. There are also a number of studies and methods related to the use of convexity, and convex analysis is typically used when analysing textbook economics.

What you need to know about betavexity.

The beta coefficient is a marker that indicates whether an investment is more or less volatile than the market as a whole, and betavexity helps to analyse the health of portfolios that have a similar nature to indices that feature financial instruments with shorter maturities – meaning the financial instruments will end or need to be renewed after a relatively short period.

In this way, betavexity has similarities with bond convexity and gamma, which are analysis tools used with financial products such as options and bonds.
