The city of Wuhan is a city where the virus known as Covid-19 was discovered and spread massively to various countries. President of the Republic of Indonesia, Mr. Joko Widodo even set April 13, 2020 through presidential decree (presidential decree) No. 12 of 2020 as a national disaster. Restrictions on economic activity throughout the country led to a decrease in economic growth including activity in the Indonesian capital market. This research study aims to analyze the impact of the covid-19 announcement as a national disaster on stock trading activities that are produced with stock returns, abnormal returns, and trading volume activities in LQ 45 companies. Each variable is calculated and compared before and after the announcement of Covid-19 as a national disaster in Indonesia. The T test (different test) is used to test whether or not there is a difference between each variable. Indonesia stock exchange daily activity data 30 days before and 30 days after the covid-19 announcement are compared. The results showed a significant difference between previous and post-Covid-19 activities.
