How markets react to news: the gap, not the figure

Markets react to news by a mechanism quite different from the way it is usually told. Price does not rise
because the news was good — it moves because the figure released differed from the figure the market was
waiting for. Understanding that explains why a “good” report can still send price down, and why reading the
news and then trading in its direction is a systematic way to lose money.

This article splits the mechanism into three checkable parts: the expectation already in the price, the gap
against that expectation, and the execution conditions in the minutes around the release. The third part is the
only one you control, and it is the one most often ignored.

Price reacts to the gap, not to the figure

Before any significant release the market has a consensus forecast, and open positions reflect it. Which means
that if the figure comes in exactly at forecast, in principle there is no reason for price to move — that
information is already in the price.

What moves price is the gap: actual minus forecast. An employment report producing a good number that is still
below forecast is bad news relative to expectations, and price can move opposite to the way the headline describes
it.

This is why reading the news faster than other people is not much of an edge. The information reaches everyone
at essentially the same moment, and most of the reaction happens in the first seconds, driven by automated systems.
By the time you have read the headline and clicked, the largest part of the move has usually passed.

There is a harder part still: the reaction is not only to the figure but to the wording around it. In policy
announcements the language about future direction usually matters more than the decision itself — because the
decision was forecast and the guidance was not. The
Federal
Reserve’s FOMC calendar publishes meeting dates and statements, and that is where to read the wording rather
than take it second-hand.

Why good news still sends price down

Beyond the gap against expectations, three further mechanisms decouple direction from content. Knowing all
three stops you looking for the explanation inside the report.

The first is position closing. Traders who entered earlier on the forecast take profit when the figure arrives
as expected. That closing flow runs against the direction of the news, and in the first minutes it can outweigh
new flow. Most cases of “the news was right and price went the other way” are this.

The second is one number changing how another is read. A high inflation print can be read as a signal that rates
will stay high, which hits assets in a quite different direction from reading it as a standalone economic indicator.
Same figure, two readings, two directions.

The third is the secondary figures in the same report. A release usually contains several measures, and the market
may ignore the headline to react to a sub-measure it considers more reliable. News summaries almost always talk about
the headline.

The practical conclusion: direction after a release cannot be inferred from the content of the release, even if you
read it correctly and quickly. That is not a skill problem, it is a property of the mechanism.

Execution conditions around the release

This is the only part of the story you can check in advance, and it decides most of the actual damage. In the
minutes around a major data point, three things deteriorate at once.

Spreads widen, by a multiple of normal, raising your entry cost precisely when the opportunity looks largest.
Slippage grows, with the difference leaning against you when liquidity is thin — a stop loss is subject to the same
mechanism: triggered at your level but filled at a worse one. And a tight stop can be triggered by the widening
itself rather than by price going against you; price returning to your direction afterwards does not help, because
the position is already closed. That is the situation that leads traders to conclude their analysis was right and
they still lost.

Three kinds of data point

Not every line on the calendar deserves attention. Sorting them into three kinds tells you when to stand aside
and when you can trade normally.

The first is a monetary policy decision: the widest and longest-lasting effect, because it changes the whole level
of expected rates, and the guidance language usually matters more than the decision. This is the group to stay out of
entirely if you trade meaningful size. Calendars for these are published well in advance — the
ECB Governing
Council calendar is one example.

The second is periodic economic data on labour, inflation and activity: strong effect over hours to days, with a
consensus forecast available beforehand, so the gap is what decides. This group moves the pairs containing the matching
currency more than others.

The third is an event not on the calendar: neither timing nor size can be predicted, so there is no way to prepare
by positioning in advance. What you can do is keep risk small enough that a surprise does not cause damage outside the
plan.

One detail on timing: US data points typically land in the Vietnamese evening, overlapping the most liquid window of
the day. That is both an advantage and a risk — spreads are tighter, but moves are larger.

Using the calendar without trading the news

The calendar is a tool for deciding when not to trade, and for deciding size — not a source of direction. Two
minutes each morning is enough: filter to the currencies you actually trade, note the high-impact releases and their
times, check the time zone the calendar is displaying, and write those times into your own calendar alongside any press
conference. Then compare them against when you expect to be opening or holding positions.

Two further points. Two calendar sites can show different forecast figures for the same indicator, because each
compiles its own consensus from the analysts it follows — so the “gap against forecast” you read depends on the source;
use one consistently. And a release should be read through the chain it affects, not on its own: the route from an
inflation print through rate expectations to a currency is set out in
CPI, inflation and forex.
