## What is rho in?

Rho is the rate at which the price of a derivative changes relative to a change in the risk-free rate of interest. Rho measures the sensitivity of an option or options portfolio to a change in interest rate. The most common Greeks are delta, gamma, vega, theta and rho.

## What is rho constant?

ρ-value (rho-value) A measure of the susceptibility to the influence of substituent groups on the rate constant or equilibrium constant of a particular organic reaction involving a family of related substrates.

## What is the micro symbol called?

Micro (Greek letter μ (U+03BC) or the legacy symbol µ (U+00B5)) is a unit prefix in the metric system denoting a factor of 106 (one millionth). Confirmed in 1960, the prefix comes from the Greek μικρός (mikrós), meaning “small”. The symbol for the prefix is the Greek letter μ (mu).
