The efficient market hypothesis (EMH) in the stock market index is validated by utilising autocorrelation, Kwiatkowski Phillips Schmidt Shin (KPSS), and variance ratio tests. The tests constituted of daily, extreme maximum and minimum, and three sub-periods data reflecting different economic condition in the market. Results indicated the strong influences of the financial crisis in the series movement. Mixed evidences were acquired; nonetheless, the overall results show that the Malaysia extreme stock return does not follow a random walk, only the series during the crisis and recovery period are in weak-form market efficiency. </p>}, number={2}, journal={MATEMATIKA}, author={Marsani, Muhammad Fadhil and Shabri, Ani and Basri Badyalina and Mat Jan, Nur Amalina and Mohd Kasihmuddin, Mohd Shareduwan}, year={2022}, month={Aug.}, pages={141–155} }
