About EarningsMoveBook

A small tool that does one useful job clearly.

Editorial review required before launchBuild edition: September 2026Sources and limits below

Compare pre-earnings implied moves from straddle pricing with actual post-event history. Explore past surprises and calculate a fresh range.

Built around the question

The core tool is free to use. There is no login wall, mandatory email capture, or paid unlock hiding the calculation. Inputs, exports, and methods belong together so you can inspect the result rather than take a black-box score on faith.
