In a B.I.G. Tips report released Friday to Bespoke Premium subscribers, we detailed how the current earnings season has compared to past earnings seasons so far. 

Since Alcoa (AA) reported earlier this month, 159 US companies covered by analysts have released earnings. Below we list the best and worst performing stocks (>$10/share) in reaction to their earnings reports. We measure this by looking at the change on the first trading day following the company's report. For companies reporting in the morning, we use that day's change, and for companies reporting after the close, we use the following day's change. So far, Sunpower (SPWRA) has had the best response to earnings, rallying 24.55% on the day. Sunpower is followed by Continental Airlines (CAL), ICU Medical (ICUI), Peabody Energy (BTU), and Nucor (NUE). Other notables on the list of winners include GE, Briggs & Stratton (BGG), Monsanto (MON), and JB Hunt Transport (JBHT). On the downside, Badger Meter (BMI) has had the worst reaction to earnings, declining 28.9%. BMI is followed by Domino's Pizza (DPZ), Piper Jaffrey (PJC), and State Street (STT).
