Hedgelaying (or hedge laying) is the process of partially cutting through and then bending the stems of a line of shrubs or small trees, near ground level, without breaking them, so as to encourage them to produce new growth from the base and create a living ‘stock proof fence’.

In mathematical finance, the Greeks are the quantities (known in calculus as partial derivatives; first-order or higher) representing the sensitivity of the price of a derivative instrument such as an option to changes in one or more underlying parameters on which the value of an instrument or portfolio of financial instruments is dependent.
It further neglects the cost of hedging the Vega risk. This has led to a more general formulation of the Vanna-Volga method in which one considers that within the Black–Scholes assumptions the exotic option's Vega, Vanna and Volga can be replicated by the weighted sum of three instruments:
The superhedging price is a coherent risk measure.The superhedging price of a portfolio (A) is equivalent to the smallest amount necessary to be paid for an admissible portfolio (B) at the current time so that at some specified future time the value of B is at least as great as A.

A hedge or hedgerow is a line of closely spaced (3 feet or closer) shrubs and sometimes trees, planted and trained to form a barrier or to mark the boundary of an area, such as between neighbouring properties.

The main principle behind the model is to hedge the option by buying and selling the underlying asset in a specific way to eliminate risk. This type of hedging is called "continuously revised delta hedging" and is the basis of more complicated hedging strategies such as those used by investment banks and hedge funds.

It is used for turning around with farm implements during field operations and is the first area to be harvested to minimize crop damage. The rows run perpendicular to the lay of the field and are usually two, three or four times the width of the implement used for planting the field.
