Research samples are 108 companies listed in LQ45 index of Indonesian Stock Exchange 2013-2016. Information research is measured by event return volatility, information efficiency, change of standard deviation of daily return, and bid-ask spread. Data analysis uses common-effect regression for event return volatility, change of standard deviation of daily return, and bid-ask spread; and random-effect regression for information efficiency. The result shows that XBRL implementation by LQ 45 companies has negative effect on information risk. It indicates that XBRL implementation reduce information risk by decreasing of return volatility, standard deviation of stock return, change of standard deviation of daily stock return, and bid-ask spread. XBRL implementation is useful for improvement of information accuracy, reducing of information asymmetry, reducing of error, and allows investor to make stock investment decision rapidly, accurately, and low cost.
