Guidance
Definition
Guidance is forward-looking financial projections that a company's management provides for upcoming periods — typically covering expected revenue, earnings, or margins — and the market's reaction is often driven more by guidance than by the actual results reported.
Example
“They beat earnings by $0.15 per share, but guided Q3 revenue 8% below analyst estimates. Stock dropped 12% in 30 seconds. The beat didn't matter — guidance was the whole story.”
Detailed Explanation
Stock prices are fundamentally about the future, not the present. Investors and traders don't pay for what a company earned last quarter — they pay for what they expect it to earn in future quarters. This is why guidance moves stocks more than the actual results. A company can report record profits and sell off if guidance suggests growth is slowing. A company can miss estimates but rally if management raises future guidance. The market is constantly re-pricing expectations, and guidance is the single most direct input into those expectations.
There are different types of guidance, and they're not all equally reliable. Some companies provide detailed quantitative guidance (specific revenue and EPS ranges). Others give only qualitative guidance ("we remain cautiously optimistic"). Some companies refuse to provide guidance at all. Wall Street analysts fill the gap by creating consensus estimates, and the "beat or miss versus consensus" framework is what drives the immediate post-earnings reaction. Learning to read sell-side analyst notes and understand consensus positioning before earnings is a useful skill for earnings traders.
Day traders focused on earnings plays need to understand that the initial reaction to guidance can be both fast and wrong. Markets often overshoot on both sides — an initial 15% drop can be partly recovered when analysts and institutional investors review the guidance more carefully and decide the initial reaction was overdone. For day traders, the post-earnings fade or continuation in the first 30–60 minutes often offers cleaner trading than the first 60 seconds of chaos after the report drops.
