In this study, we have attempted to seek evidence for weak-form of market efficiency for KSE 100 Index because over the last five years KSE 100 Index has shown substantial growth as compared to other emerging stock markets. Index returns have been studied from 1st January, 1992 to 30th April, 2013. For further analysis, return series has been divided into sub-periods. The paper has made use of primarily Non-Parametric tests as well as parametric tests. For further analysis, Runs test has also been run on 20 companies return series for comparison purpose with the results of index return series. In addition, from KSE 30 Index, 20 companies return series based on the free-float of shares have also been analyzed through Runs test to check if increase in numbers of floating shares does increase the randomness in return series or not. To our knowledge, this paper is the first one on KSE 100 Index to study the overall time frame of return series of KSE 100 Index of 22 years with the several random walk and weak-form efficiency tests to ensure the consistency of results; and to compare the results of runs test of index return series with the results of runs test on companies return series from KSE 100 and KSE 30 Indexes. Overall KSE 100 Index has been found to be weak-form inefficient, but unlike other studies, our study illustrates how the last 4 years have shown some signs of efficiency. Companies return series from KSE 30 Index are found to be more random than companies return series from KSE100 Index.

This study examines the valuation, liquidity, volatility, and efficiency before and after the integration of Islamabad Stock Exchange (ISE) and Lahore Stock Exchange (LSE) with Karachi Stock Exchange (KSE) to form the Pakistan Stock Exchange (PSX). The firm level daily data is analyzed to determine the effects of regulatory change. Based on regression analyses, results indicate mixed evidence for different market measures following the integration of domestic bourses. However, the post-integration period in Pakistan is fraught with political turmoil and weak economic indicators. Thus any improvement that is hypothesized following the merger is offset by poor economic and political factors.

This paper has investigated the Efficient Market Hypothesis (EMH) through the concept of lead-lag relationship of the future market prices and spot market prices in the context of Pakistani stock market. The study has used data of randomly selected one hundred and forty firms listed on the Karachi Stock Exchange from January 1995 to March 2012. Spot and future indices were developed from the closing prices through the Price-Weighted index method. First stationarity of the data was checked through Augmented-Dicky Fuller test; then GARCH (1,1) model was estimated for both the spot and future index returns in order to investigate the volatility in either of the index. The results of GARCH (1, 1) suggest that the impact of the previous day volatility in both the spot and future index has impact on the current day volatility. The future market price volatility has more prominent role to explain the spot market prices as compared to that of the explanatory power of the future market prices based on the spot market prices. Therefore, it is concluded based on the GARCH (1,1) there exists lead-lag relationship between the future and spot index where future market leads the spot market. Granger casualty test has been used to triangulate the results of GARCH (1,1) model. The results showed that future market Granger causes the spot market while the spot market does not Granger causes the future market. Thus, it can be concluded that it is the future market prices that lead the spot market prices and thus there exist a Lead-Lag relationship between the future and spot market prices in Karachi Stock Exchange and one can predict changes in spot market price based on the changes in the future market price. Moreover, these empirical results support the view that it's the future market where information is created about the security prices and then it disseminates to the spot market.

"The World Scientific Handbook of Futures Markets serves as a definitive source for comprehensive and accessible information in futures markets. The emphasis is on the unique characteristics of futures markets that make them worthy of a special volume. In our judgment, futures markets are currently undergoing remarkable changes as trading is shifting from open outcry to electronic and as the traditional functions of hedging and speculation are extended to include futures as an alternative investment vehicle in traditional portfolios. The unique feature of this volume is the selection of five classic papers that lay the foundations of the futures markets and the invitation to the leading academics who do work in the area to write critical surveys in a dozen important topics."--$cProvided by publisher.
