Do Sleep Disorders Affect Stock Markets? Evidence from Borsa Istanbul
The aim of this study is to investigate the effect of “daylight saving time” (DST) changes on Borsa Istanbul, covering the periods from 1988 to 2015. In this context, daylight saving anomaly was examined by using stock market returns and volatilities following DST changes on daily and weekly basis. The results indicate that both market returns and volatilities following daylight saving time changes do not differ from other days and weeks. Thus, it can be said that there is no evidence of daylight saving time effect in Borsa Istanbul.
