Use historical post-earnings behavior to frame the next event, not to assume the next quarter will repeat the last one.
What this page tells you
It shows how the stock has reacted to past earnings, including surprise history, average move size, and whether upside or downside reactions have tended to dominate.
How traders use it
Compare historical realized moves with the next implied move to judge whether options are pricing too much, too little, or roughly enough event risk.
What matters most
Recent quarters, current guidance, and current IV usually matter more than distant history, especially when the business or macro regime has changed.
Historical earnings behavior is best used to prepare for the next event before you choose a structure and size the risk.
