    An Empirical Test of the Validity of the Capital Asset Pricing Model on the Zimbabwe Stock Exchange
    (2016) Nyangara, Melody; Nyangara, Davies; Ndlovu, Godfrey; Tyavambiza, Takawira
    We test the empirical validity of the capital asset pricing model (CAPM) on the Zimbabwe Stock Exchange (ZSE) using cross-sectional stock returns on 31 stocks listed on the ZSE between March 2009 and February 2014. We conclude that, although the explanatory power of beta tends to fall rapidly for prediction horizons >6 months, beta significantly explains average monthly stock returns on the ZSE. Tests to validate the CAPM reject its validity for the ZSE however, primarily due to liquidity and skewness anomalies. We nevertheless fail to detect any size effects. There is encouraging evidence to suggest that the CAPM performs reasonably well in predicting average monthly returns over prediction horizons of between 3 and 6 months. We recommend that investors and analysts must exercise extreme caution in applying the CAPM. Furthermore, we discourage strategies based on the existence of a size premium on the ZSE. Instead, investors may consider neglected and negatively skewed stocks, albeit over appropriate horizons. Further research on other African Stock Markets will help verify if the optimal performance range of the CAPM is indeed 3-6 months. Development of standard continental proxy market portfolios will also improve the estimation of betas and enhance results of cross-country tests of the CAPM.

    Financial Sector Development and Economic Growth: Evidence from Zimbabwe
    (EconJournals, 2013) Ndlovu, Godfrey
    The relationship between financial system development and economic development has attracted interest of a number of researchers all over the world, however institutional differences and capital allocation variations between and within economies, make it very difficult to generalize findings and thus increasing the need for country-specific studies. This study examines the causal relation between financial system development and economic growth from a Zimbabwean perspective, based on two inter-related broad aims, the first being the established of cointegration relationship between the two and the ultimate direction of the causal relationship. Using multivariate Granger causality test the study finds existence of demand following financial development in Zimbabwe, there is unidirectional causality from economic growth to financial development. Financial system development is therefore an outcome of the pressure for institutional development in capital markets and introduction of modernized financial instruments. As such policy concern should focus on trade liberalization and other related activities in order to spur economic growth, since financial system development is a passive reaction to economic growth. Such policies might include investment promotion and removal of barriers for foreign investments.
