In quantitative finance, 'the Greeks' refers to a set of measures used to assess the
sensitivity of options and other derivatives to various factors. These factors are typically related
to the underlying asset, time, volatility, and interest rates. The Greeks are named after letters
from the Greek alphabet, such as Delta, Gamma, Theta, Vega, and Rho. They play a crucial role in
understanding and managing the risks associated with options and other derivative positions.
