FYI: Through Monday, roughly 2,400 companies had reported their Q1 2015 numbers since earnings season began on April 8th. Below is a chart showing the one-day change on earnings reaction days for every stock that has reported this season. For companies that report in the morning before the open, that trading day is its earnings reaction day. For companies that report after the close, the next trading day is its earnings reaction day.
