The Influence of Weather and Calendar Cycles on Trading Volumes at World Stock Exchanges
Kovaľová, Andrea ; Vozárová, Pavla (advisor) ; Slaný, Martin (referee)
Studies investigating stock-exchange anomalies -- mainly with respect to returns and volatility -- have been emerging in recent years and decades. This work explores whether weather conditions, days of the week, length of daylight, seasonal affective disorder, holidays, and lunar phase affect trading volume. Segmented into two parts, the work primarily analyses time-series cross-sectional data covering 12 major stock exchanges and spanning from January 2010 to March 2015. The other part of the work focuses on a detailed analysis of the New York Stock Exchange using only time-series data obtained for the time period from January 2001 to December 2009. Additionally, this period is further split to two time spans as the NYSE fundamentally changed its trading system during the period in question. We find strong evidence of the Monday effect -- manifested in low trading volume on Mondays -- recognizable in the time-series cross-sectional part of the analysis, as well as in the time-series part. Other aforementioned anomalies either do not affect the trading volume significantly or their effect is statistically significant only in one of the two parts of the analysis.
