relation between market capitalization and stock market indices at Nairobi Stock Exchange (NSE). The various functions fulfilled by market indices make it important to assess their suitability as indicators of market performance alongside the market capitalization.The Nairobi Stock Exchange was used as the case study. The study employed time series analysis where E-views software was used to analyze the data to assess the relation among the variables. The study established that there exists a strong positive relationship between market capitalization and the NSE indices. However, the NSE-20-share index was found to be more significant in explaining most of the changes in the market capitalization than the NASI. This was mainly due to the nature and composition of the indices. Within that period of study, it was determined there was a very strong positive correlation between market capitalization and NASI and a rather moderate positive relationship between market capitalization and NSE 20 share index. ix CHAPTER ONE: INTRODUCTION 1.1 Background of the study Stock markets have existed for a number of centuries and have historically played a significant role in economic development by facilitating mobilization of long term capital (Ngugi, 2003). They do so by providing liquidity to various market players. Stock markets also provide investors with a platform for investing in various financial instruments (both underlying assets and derivatives). Key drivers in these markets are the returns and capital gains from respective securities. As a result, accurate measurement of the stock market performance is critical to information users as it helps to understand the demand, liquidity and return levels as well as the ease with which investors can mobilize capital. 1.1.1 The Concept of Market Capitalization and Stock Market Index Olson (2005) defines market capitalization as the price of a stock at any given time multiplied by the amount of shares outstanding. From a market perspective, market capitalization comprises the sum of individual outstanding shares by their prices for all the companies listed in a given stock market. According to Olson market capitalization can be classified as follows; one, large –cap ranging from $10 – 100 billion; mid-cap ($ 1 – 10 billion); Small-cap ($100 million – 1 billion) and micro-cap ($10 - $ 100 million). Olson notes that there
