In partial significance test variable inflation rate does not affect the JCI, while the variable exchange rate of USD / IDR and SBI interest rate showed significant results with a coefficient of 0.18 and 3.29. Recommendations that can be given is, the investor community should be more selective in choosing stocks that want to have.
