Forecasting and trading on the VIX futures market: A neural network approach based on open to close returns and coincident indicators
No full textPrevious work has highlighted the difficulty of obtaining accurate and economically
significant predictions of VIX futures prices. We show that both low prediction errors and
a significant amount of profitability can be obtained by using a neural network model
to predict VIX futures returns. In particular, we focus on open-to-close returns (OTCRs)
and consider intraday trading strategies, taking into account non-lagged exogenous
variables that closely reflect the information possessed by traders at the time when
they decide to invest. The neural network model with only the most recent exogenous
variables (namely, the return on the Indian BSESN index) is superior to an unconstrained
specification with ten lagged and coincident regressors, which is actually a form of
weak efficiency involving markets of different countries. Moreover, the neural network
turns out to be more profitable than either a logistic specification or heterogeneous
autoregressive models
