This study investigates impacts of sell-side analysts in the liquidity of firm’s shares of Brazilian Capital Markets. Liquidity hypothesis studied by Brennan and Subrahmanyan (1995), Brennan and Tamarowski (2000), Amihud and Mendelson (1986, 2000) and Amihud et al. (1997) defines that an increase in the number of analysts covering a particular stock increases its liquidity causing a positive impact on the stocks prices. This work investigates empirically whether increasing number of securities analysts impacts stock market liquidity, as observed in the American market by Brennan and Tamarowski (2000), using a sample of 179 listed stocks in the Brazilian stock exchange, BM&FBovespa. This work determines liquidity-measuring firm’s Lambda dollar derived by Kyle (1985) and then applying cross section regression of Lambda dollar as dependent variable and number of analysts as independent variable. Results indicate that stock market liquidity increased with number of securities stock analysts in favor of liquidity hypothesis.
