Why News Moves Markets

The Expectations Game

Markets do not move because of news. Markets move because of the difference between what was expected and what actually happened. This distinction is the most important concept in event trading.

On January 10, 2024, the Bureau of Labor Statistics reported that the US economy added 216,000 jobs in December 2023. That sounds like a strong number. Yet whether the market rallied or sold off on that report had nothing to do with the absolute number of 216,000. It depended entirely on what traders expected.

If the consensus estimate was 170,000 jobs and the actual was 216,000, that's a positive surprise β€” more jobs than expected, stronger economy. In normal conditions, stocks might rally. But in an environment where the Federal Reserve is watching employment data to decide on interest rate cuts, a "too strong" jobs number means rate cuts are less likely β€” which can crash both stocks and bonds.

This is why experienced event traders never ask "was the number good or bad?" They ask "was the number above or below consensus, and what does that mean for the current macro narrative?"

Consensus Estimates: What's Priced In

Before every major economic release, economists and research desks publish consensus estimates β€” the median forecast from a survey of analysts. These estimates are freely available on financial calendars (like the one built into PropTally, Investing.com, or ForexFactory).

For the January 2024 NFP example:

  • Consensus: 170,000 jobs
  • Actual: 216,000 jobs
  • Surprise: +46,000 above expectations

The consensus estimate represents what is already priced into the market. When the actual number matches consensus perfectly, the market reaction is typically muted because participants have already positioned for that outcome.

The tradeable opportunity comes from deviations β€” when reality diverges from expectations. The larger the deviation, the larger the price move as participants scramble to reposition.

Key data points that move markets most:

  • Non-Farm Payrolls (NFP): Released first Friday of each month at 8:30 AM ET. Often produces 50-100 point moves on ES.
  • Consumer Price Index (CPI): Released mid-month at 8:30 AM ET. The most important release for interest rate expectations.
  • FOMC Statement & Press Conference: Eight times per year at 2:00 PM ET. The Fed's own words on monetary policy direction.
  • GDP: Released quarterly. Market-moving when it deviates significantly from forecasts.

Market Positioning: The Hidden Variable

The consensus estimate tells you what's expected. Market positioning tells you how traders have bet on that expectation β€” and this matters enormously for the direction of the reaction.

Positioning refers to the aggregate directional bets held by market participants before an event. If most traders are long going into NFP (expecting strong data to be positive for stocks), the reaction to an in-line or slightly positive number may be a sell-the-news event because there are no remaining buyers β€” everyone who wanted to be long already is.

Conversely, if positioning is heavily short (traders expecting a weak number), even an in-line print can cause a short squeeze as those shorts cover, producing a rally.

Sources for positioning data:

  • CFTC Commitment of Traders (COT): Weekly report showing futures positioning of commercial hedgers, large speculators, and small speculators. Available for free from the CFTC website every Friday.
  • Options open interest: High put/call ratios suggest bearish positioning. Extreme skew in options pricing reveals where the market expects volatility.
  • Analyst commentary: Investment bank research desks often describe client positioning in their pre-event notes. Phrases like "consensus long" or "market is leaning short" are valuable intel.

The Repricing Mechanism

When a surprise occurs, the market must reprice β€” participants update their models and adjust positions accordingly. This repricing creates the rapid, volatile price moves that event traders seek.

The repricing process typically follows three phases:

  1. Algorithmic reaction (first 1-5 seconds): High-frequency trading systems parse the data release and execute pre-programmed trades. This creates the initial spike that you see on the chart.
  1. Institutional flow (next 1-30 minutes): Larger players β€” hedge funds, banks, asset managers β€” analyze the data in context and begin positioning. This is where the initial move either extends or reverses.
  1. Narrative formation (next 1-4 hours): The market decides on a narrative. "CPI was hot, so rate cuts are off the table" becomes the story, and this narrative drives positioning for the rest of the day and beyond.

Understanding these phases is critical for timing event trades. Retail traders who react to the headline during phase 1 are competing against algorithms that are faster. The opportunity for human traders is in phase 2 and phase 3, where contextual analysis and narrative judgment matter more than speed.

Setting the Foundation

This course will teach you specific strategies for each type of market-moving event. But every strategy builds on this foundational framework: markets price expectations, surprises move prices, positioning determines magnitude, and repricing creates opportunity. Keep these principles in mind as we dive into specific event types in the lessons ahead.

Key takeaways

  • Markets move on the difference between expectations and reality β€” a "good" jobs report can crash markets if expectations were even better
  • Consensus estimates from economists and analysts represent what is already priced in before the event occurs
  • Market positioning before events (long-heavy or short-heavy) determines the direction and magnitude of the initial reaction
  • Repricing events force participants to update their models, creating rapid price discovery that produces trading opportunities
