The design of the analysis used was multiple linear regression using secondary data while the hypothesis testing used T-Tests and F-Tests. The findings of this study were fluctuations between inflation, world crude oil prices, and the Composite Stock Price Index (CSPI) in each year. Statistical analysis proves that simultaneously Inflation and World Crude Oil Prices have an effect on the Composite Stock Price Index (CSPI). Morever, while partially shows that inflation affects the Composite Stock Price Index (CSPI) and World Crude Oil Prices affect the Composite Stock Price Index (CSPI).
