Using a sample of VN30 baskets of Vietnamese listed firms (excluding the financial institutions) in the Ho Chi Minh Stock Exchange (HOSE) from 2015 to 2018 and the Google trends data from the same period, the study examines investigate the possible relationship between Google trend and the earnings response coefficient. The results from regression indicate that the ERCs of Vietnamese firms is positive and the interest of the firms on the Internet has no significant impact on ERC.
