Why markets often move before the news and fade after it. Trading around the calendar, calmly.
Big scheduled events — the national BudgetA plan for how you’ll spend and save your income., elections, central-bank meetings, major policy announcements — generate enormous attention and anxiety among investors. But markets react to them in a counter-intuitive way that, once understood, lets you stay calm around the calendar.
The key principle, echoing earnings:
markets are forward-looking, so they move on anticipation and surprise — often moving before a known event and fading after it (“buy the rumour, sell the news”). Because a

known in advance, the market spends the run-up
pricing in the expected outcome — so by the time the event arrives, much of the “obvious” move has already happened. What moves price on the day is the
surprise relative to those expectations, not the event itself; if the outcome matches what was priced in, the market may
fall after good news (the anticipation is over) or rally on relief once
uncertainty is removed (markets often hate uncertainty more than bad news, so simply
getting clarity — even an imperfect result — can spark a relief rally). This produces the classic patterns: pre-event

surprises, and a frequent “fade” once the event passes and the priced-in expectation is realised. For investors, the calm conclusions: (1) don’t make big bets
on binary events — the outcome
and the market’s pre-positioned reaction are both hard to predict, and
volatilityThe size of price swings — not their direction. is elevated; (2) the
long-term impact of most events is far smaller than the short-term noise suggests (elections and budgets rarely change a good company’s decade); and (3) the disciplined move is usually to
stay the course through the event rather than trade the calendar. Recognise that the market has likely already discounted the obvious, and that uncertainty-removal itself can drive moves — then react calmly to the
surprise, not the headline.
- Markets are forward-looking — they price in known events in advance, so the move often happens before the event.
- On the day, the surprise (vs expectations) moves price — “buy the rumour, sell the news”; good-but-expected news can fade.
- Uncertainty removal — markets hate uncertainty, so even an imperfect result can spark a relief rally once clarity arrives.
- Calm conclusions — don’t bet big on binary events; long-term impact ≪ short-term noise; usually stay the course.
ExampleAhead of a
BudgetA plan for how you’ll spend and save your income., the market rallies for weeks on
expectations of pro-growth measures. The
BudgetA plan for how you’ll spend and save your income. delivers roughly what was expected — and the market
falls the next day (“sell the news,” the anticipation already played out). After a
tense election, the result removes uncertainty and the market
rallies in relief — even though the outcome was merely “clarity,” not unambiguously bullish. Both confounded those who traded the headline rather than the surprise.
Key takeawayMarkets price in known events in advance, so they often move before the event and fade after (“buy the rumour, sell the news”); only surprises vs expectations move price on the day, and uncertainty-removal alone can spark relief rallies. The long-term impact of most events is far smaller than the short-term noise — so don’t bet big on binary events; usually stay the course and react calmly to surprises, not headlines.
