Time Series Analysis of Prices and Quantities at the Bulgarian Electricity Exchange in Conditions of Low Liquidity
Summary:
This article analyzes the time series of prices and quantities on the Bulgarian electricity exchange. The focus is on the period between January 2016 and June with the assumption that in this initial period for its operation, the stock exchange trade is not sufficiently liquid. Statistical tests and seasonal decomposition of quantities and prices are made. This allows the determination of their statistical properties. The analysis shows that both time series are characterized by mean reversion and have a weekly seasonality.
