This study examines the factors that affect the reaction of market to quarterly earnings announcements of firms listed on the Tehran Stock Exchange. Five factors including the timing of earnings announcements, firm size, industry, the number of earnings announcements, and the number of other announcements are investigated. We used event study methodology. The market reaction is examined by investigating stock trading volume and price changes, during 20 days before to 20 days after the announcement day. For a sample of 523 earnings quarterly announcement (by 94 companies) during 1383 to 1386 (first quarter), we show early announcements have more information content than later announcements.
