UNIVGARCH implements various
Garch models (including N-GARCH, E-GARCH and O-GARCH). Proprietary optimisation
techniques implemented under 32-bit Windows are utilised which finally enable
the practical use of Garch models in a trading environment. The Garch model
increases the accuracy in the pricing of standard and exotic options (including
Windowed Barriers and Windowed one and two touch options) where the underlying
does not follow a perfect lognormal distribution (e.g. it has fat tails or
non-standard Kurtosis). The Garch model has been proven more accurate than
"Black-Scholes" type models, especially for out of the money options which are
close to maturity.
The Garch model is considered an effective volatility
forecaster. UNIVGARCH thus enables the forecast of
the forward volatility for any time period and this volatility forecast can also
be used in a standard option pricing model, increasing the accuracy of the
standard option pricing model.
Simulations can be carried out with variable step length,
including the handling of discrete dividends and a term structure of interest
rates. These substantially increase the accuracy and types of options which can
be analysed. Advanced variance reduction techniques are also implemented to
substantially increase the accuracy/speed ratio.
UNIVGARCH can also be used for
the Monte-Carlo pricing of standard and exotic options assuming a constant
volatility, therefore increasing the scope of usage to situations where a
standard log-normal distribution is desirable.
The add-in is fully callable from Excel, Visual Basic, C, C++,
Access etc.
