Presence of Day-of-the-Week Effect in the Karachi Stock Market

Musarrat Shamshir, Khalid Mustafa


This study investigates the day-of-the week (DOW) effect and volatility in Karachi Stock Exchange (KSE), from 2009-2013, using all four indices in the exchange. The objective is to assess the reliability of the four indices working at KSE, from investor perspective of portfolio and risk management of KSE. By using OLS and autoregressive technique with lagged value of returns the study shows Tuesday and Thursday effect in case of KSE-100 and KSE-all share respectively. No DOW effect in KSE-30 and in KMI-30 indices found. This is in favour of the free-floating concept of shares in these indices. The GARCH (1,1) technique with student’s t distribution revealed highly persistent volatility in  KSE-100 index, comparatively less persistent shocks in KSE-all share and KSE-30 index and a rapid decay in KMI-30.

Keywords: Day-of-the-week effect; KSE-100 index; KSE-30 index; KMI-30 index; KSE-all share index; GARCH (1,1)
