Greeks (in finance)

In finance, "Greeks" refer to a set of metrics used to measure the sensitivity of an option's price to various factors. The main Greeks include Delta (price sensitivity to the underlying asset's movement), Gamma (rate of change of Delta), Theta (time decay of the option's price), Vega (sensitivity to volatility), and Rho (interest rate sensitivity). Understanding these helps traders assess risks and make informed decisions about buying or selling options, thereby enhancing their strategy in managing investments and hedging against market movements.
