The Earnings Reaction Graph is an exclusive feature for Platinum members (to learn about Slope memberships, click here). This page presents to you all the historical reactions from company earnings announcements.
Once you are at the page, all you have to do is enter a ticker symbol and click Go (or press the Return key). By default, the stock ticker AMZN is entered for you.
When you enter a ticker symbol, you can see the immediate reaction a given stock had during all of its prior earnings periods from longest ago (left side) to most recent (right side). The black line is the average of all of them, and you can turn this black line on and off with a checkbox. Also, you can point to any one of these bars to see the date of the event and the percentage-based price reaction. This tool is especially helpful to options traders.
There are actually two modes to display these reactions, however. One of them, Net Change, is the default, and it succinctly shows you the net percentage change at the end of the day following the announcement.
If you click the Full Bar radio button, however, you will see the information presented in a different way:
Specifically, you are seeing the entire day’s bar, in percentage terms, following the earnings announcement. So instead of seeing just one data point (the net percentage change of the closing price) you are seeing four (the percentage change for the open, high, low, and close for the entire trading day). This might be a more desirable presentation of the information for you since it is more complete.
Note that whereas in the first mode, red and green indicate a loss or a gain, the colors in the other mode are instead representing whether the close price was higher than the open (green bar) or lower (red bar).
