Forecasting Stock Market Volatility: The Gains from Using Intraday Data
2016
There is evidence that volatility forecasting models that use intraday data produce superior forecast accuracy as compared with that delivered by the models that use daily data. However, this evidence is still sparse and incomplete in the stock markets. This paper extends previous studies on forecasting stock market volatility in several important directions and comprehensively assesses the gains in forecast accuracy provided by intraday data. First, we use an extensive set of intraday data on 28 single stocks and 23 stock market indices. Second, in our study we use forecast horizons ranging from 1 day to 6 months. Third, we compare forecasting abilities of several competing models. We find…
The Dynamics of Quote Prices in an Artificial Financial Market with Learning Effects
2007
In this paper we study the evolution of bid and ask prices in an electronic financial market populated by portfolio traders who optimally choose their allocation strategy on the basis of their views about market conditions. Recently, a growing literature has investigated the consequences of learning about the returns process1. There has been an increasing interest in analyzing what are the implications of relaxing the assumption that agents hold correct expectations. In particular, it has been asked the fundamental question of understanding if typical asset-pricing anomalies (like returns predictability, and excess volatility) can be generated by a learning process about the underlying econ…
Customer benefits of demand-side management in the Nordic electricity market
2016
The increasing share of renewable energy sources is likely to lead to price effects in Nordic electricity market, resulting especially in increased volatility of spot and imbalance prices. The greater price volatility and amount of required balancing power increase the need for Demand-Side Management (DSM) in the electricity market and may as well increase the financial benefits of DSM participants. In this research I study the DSM in electricity mar-ket and evaluate how large the financial benefits of DSM participants could be. Monte Carlo simulation method is used to simulate imbalance prices with different volatilities for Finland and Sweden. The results show that increasing volatility m…
