The Beta of a stock is an index which measures its volatility relative to the market rate of return (Systematic risk). The beta of a stock is a critical component in not just valuing a stock but a company as well. Beta gives investors a fair idea of the risk associated with a particular security relative to the market, as such, enables them make informed decisions. Arguably, the absence of valid beta data of companies listed on the Ghana Stock Exchange (GSE) has partially contributed to the unattractiveness of the stock market as both local and foreign investors are not well informed about the risk of particular stocks. Thus, this research, seeks to provide investors and academicians with valid beta data.
