## How do you calculate arbitrage pricing theory?

Arbitrage Pricing Theory Formula

The APT formula is E(ri) = rf + βi1 * RP1 + βi2 * RP2 + ... + βkn * RPn, where rf is the risk-free rate of return, β is the sensitivity of the asset or portfolio in relation to the specified factor and RP is the risk premium of the specified factor.

## What is arbitrage pricing theory explain?

## What is no arbitrage principle?

## What is the purpose of creating a multi factor model?

Multifactor models permit a nuanced view of risk that is more granular than the single-factor approach allows. Multifactor models describe the return on an asset in terms of the risk of the asset with respect to a set of factors.
