Markets don't wait for certainty.
Before the Federal Reserve has said a word, before earnings begin, before a single government data point has been released, the market has already moved. European Central Bank researchers analyzing 21 major U.S. macroeconomic releases found that in 7 of them, prices were already drifting in the correct direction roughly 30 minutes before the official release time. Pre-announcement drift accounted for approximately half of the total price adjustment in those cases.
Half the move. Before the news.
This is not noise. It is markets doing exactly what markets do: pricing expectations, not outcomes. And once you understand that, the way you read price action around events changes permanently.
What Speculation-Driven Behavior Actually Is
Every major market-moving event has two lives. The first is the rumor phase: the period of positioning, expectation, and anticipation before the data arrives. The second is the fact phase: when the number prints and the crowd responds. Most people treat these as the same moment. They are not, and that confusion is where most trading mistakes around events are born.
"Buy the rumor, sell the fact" is one of the oldest phrases in markets, and it holds up under scrutiny. Research into investor behavior around anticipated events confirms the pattern: prices rise ahead of positive releases and frequently decline afterward, even when the outcome matches or exceeds expectations. The reason is not sentiment or irrationality. It is information timing.
The informed position gets built during the rumor phase. By the time the fact arrives, that position is already profitable or already stopped out. The news is not new to the people who matter. It is the confirmation of what they already wagered on, and for them, the trade is already over.
The Three-Phase Anatomy of a Market Event
Understanding this split between rumor and fact becomes clearer when you break any major release into its actual three-phase structure, because each phase has its own logic and its own set of participants.
Before the release
In the hours and sometimes days preceding a major data print, market makers face an acute problem: if they are quoting prices right before a surprise rate decision or an unexpected jobs number, a one-sided rush of informed orders can run them over. The rational response is to widen the spread between buy and sell prices and pull size from each level. Academic research on bid-ask spreads around scheduled announcements confirms this consistently: spreads are wider before releases, in many cases already encompassing the post-announcement closing price. The market in this window is not dysfunctional. It is pricing the risk of being on the wrong side of better-informed money.
That better-informed money is already moving. The same ECB research found price drift in the correct direction beginning around 30 minutes before official releases, driven by a combination of proprietary forecasting and the early reprocessing of publicly available data by institutional desks. The positioning is happening quietly, in a thinner and more expensive market, before the crowd arrives.
The print
When the number drops, every participant processes it simultaneously. Algorithms trigger. Risk limits fire. The result is a collision of simultaneous, often contradictory, order flow: sharp moves, wide fills, and poor execution quality in every direction at once. The initial spike is frequently the wrong direction before the real move develops. This moment feels like the most important one. For execution purposes, it is often the worst.
After the release
As the dust settles, the market begins its directional move. But that move is frequently built on the correction of an initial overcorrection. Research into post-announcement price behavior shows this repeatedly: markets with concentrated institutional attention display stronger immediate reactions followed by partial reversion toward fundamental value. The directional move after the print is real and tradeable. The noise inside the first few seconds is also real. Treating them as the same signal is where the next round of mistakes begins.
Why Retail Traders Get This Wrong
Retail traders operate, almost universally, in the fact phase. They watch the number print, assess whether it is good or bad relative to consensus, and place a trade. By the time they act, the move is already maturing.
The informed positions were built during the rumor phase, through widened spreads, when cost was highest and the crowd was thinnest. By the time the release hits, institutional desks are not watching the screen waiting to react. They are managing existing exposure, often looking for an exit into the liquidity the reaction creates. Research on institutional trading around scheduled events confirms this directly: sophisticated participants build positions ahead of anticipated announcements and sell into the announcement itself, executing a trade that is structurally over before the retail trader has finished reading the headline.
That retail trader entering on the news is not a first mover. In most cases, they are the exit. And this is not a product of manipulation or unfairness. It is market structure working exactly as designed, rewarding preparation over reaction.
What This Means for Your Trading
The implication is not that event-driven trading is impossible. It is that it has to be approached differently, starting well before the release itself.
Begin with the economic calendar. Every week, high-impact releases are scheduled and publicly known: Non-Farm Payrolls, CPI, FOMC decisions, major earnings dates. If you are holding a position through one of these without having registered it as a risk event in advance, you are not trading with a plan. You are carrying unexamined exposure.
In the window before the release, wider spreads and reduced size are not bugs. They are the market pricing information asymmetry correctly. Trading in that window costs more for a reason, and knowing that cost is part of understanding what you are actually doing.
At the print, prepare for volatility that is not yet directional. The initial spike is frequently a trap, and the first few seconds of a major release are chaos, not signal. Waiting for the initial reaction to exhaust itself before committing is not passivity. It is discipline.
After the release, when the directional move develops, you are entering in the second stage of a market that has already done its primary positioning. That means tighter size, clear awareness of where the pre-release range sat, and patience to let the noise resolve before adding exposure. The move can still be significant. But the edge available in those first seconds belongs to participants who were positioned before the number ever dropped.
Markets don't move on news. They move on the anticipation of news, and by the time the headline prints, the most important positioning is already done.
The trade before the trade is the only one that gets built on clean, uncontested information. Every entry placed in the seconds after a release is a reaction to a move that has already matured, in a market that has already absorbed the initial shock and is now working out who is left holding what. The crowd that called the number correctly is often still losing, because they called it at the wrong time and into the wrong phase.
That is what it means to say markets are forward-looking. They are not looking forward to the event. By the time you see it, they are already past it.
