Using the methodology described by Dater, Naik and Radcliff (1998) in their work "Liquidity and Stock Returns: An Alternative Test", I first examined the relationship between the rate of return and systematic risk measured by the beta coefficient and company size measured by the logarithm of market capitalization and turnover ratio (model 1) for the data collected, and obtained the results described in Table 3.
where [r.sub.i,t] - rate of return of particular stock i for a period from t-1 to t, [[alpha].sub.i] - constant of regression model, [[beta].sub.i] - regression coefficient or beta coefficient of the stock i, [r.sub.w,t] - rate of return of world market portfolio for the period from t-1 to t, [[mu].sub.i,t] - regression residual, n - number of stocks in the sample, T - periods in days, weeks, months.
