Abstract:
This study investigates the impact of inflation and the Consumer Price Index (CPI) on stock
market returns in Sri Lanka from 2007 to 2021. Inflation and the CPI are used as
independent variables, while the All Share Price Index (ASPI) serves as the dependent
variable for analyzing the stock market in Sri Lanka. Inflation, a key macroeconomic
variable, adversely affects the macroeconomic equilibrium of an economy. ASPI data was
collected from the Colombo Stock Exchange (CSE) website, with a sample of 180 monthly
observations. The objective of the research is to examine how inflation and the CPI
influence stock market returns in the Sri Lankan context and to understand the potential
implications of these variables on stock returns in the Sri Lankan capital market. The study
employs both correlation analysis and a linear regression model. The results show that
correlation analysis indicates a weak positive influence of the ASPI on inflation and the CPI.
However, the regression model reveals a significant negative relationship between the ASPI
and both inflation and the CPI.
