What it tests

Whether you can separate a headline from the surprise inside it, and link economic releases, Fed decisions and company news to the price move.

Retail sales beat forecasts; stocks close lower. A headline like that reads like a contradiction until you see what the price was carrying the night before. Prices move on the gap between what happened and what traders already expected, and on what the news implies for interest rates and future profits, so the loudest headline of the week can leave a stock perfectly still while a quiet revision to a forecast knocks it down.

That is the skill tested below. You get a release, a decision or a rumor. You work out what changed.

Why a forecast moves the price

A simple way to see it: a stock’s price is roughly the profit traders expect, multiplied by what they are willing to pay for each dollar of it.

The company’s earnings did not change in that example. The multiple did, because safer places to park money started paying more, and an investor who can earn a better return on a Treasury will only keep holding a risky stock at a price low enough to leave room for a higher return on top. A change in expected earnings works the same way through the other half of the sum.

Before you start

Read each setup for two things. What was expected? What does the news change about rates or about the company’s future profits? The answer on monetary vs fiscal policy covers who sets rates and how. The one on what a recession is and who decides explains the dating committee.

After a wrong answer

The usual trap is reading the headline as the news. If one caught you, rewrite the setup as a pair of numbers, forecast and actual, and see where the surprise sits. Then ask what that surprise does to the next rate decision or to the profits traders expect over the coming year, since those two things, the cost of money and the earnings it buys, are what the price was built on before the release came out. Keep the pair of numbers in your notes. Company releases get a closer look in Below the Beat, which goes line by line through an earnings report. The economics hub gathers the pages on rates, inflation and the business cycle.

The questions

  1. The situationA monthly jobs report is released at 8:30 a.m. The headline figure matches the consensus forecast exactly. Stock index futures barely move.

    1Why did a big release produce a quiet price?
    Show the answer

    B: The figure matched the forecast, so prices already reflected it. Prices move on surprises. Traders had positioned for the consensus number before 8:30, so a figure that lands on the forecast tells them nothing new. The same report with a large miss in either direction would have moved futures sharply.

  2. The situationA monthly inflation release comes in above the forecast. The headline reads that prices rose faster than expected. Stocks fall and Treasury yields rise within minutes.

    2What link is the market drawing?
    Show the answer

    A: Faster inflation makes rate cuts less likely, and higher rates lower what future profits are worth today. Hot inflation raises the odds that the Federal Reserve keeps rates high or lifts them. Higher yields on Treasuries make a dollar of future profit worth less today and give investors a better return without stock risk, so stock prices adjust down.

  3. The situationInterest rate futures showed traders expected the Federal Reserve to cut its policy rate at the meeting. The Fed announces it will hold rates where they are. Stocks fall.

    3Why can stocks fall when rates do not change?
    Show the answer

    D: The hold was the surprise, since the market had priced in a cut. The market compares the decision with what it expected. A cut was already in prices, so a hold works like a small tightening relative to that forecast. The same hold with no cut expected would likely have passed with little reaction.

  4. The situationA hypothetical company beats analysts' revenue estimates for the quarter. In the same release, it lowers its revenue forecast for the full year. The stock falls 8% after hours.

    4What is the price reacting to?
    Show the answer

    C: The lower forecast, since the value of the stock rests on future results. A stock's value rests on what the company will earn from here. The quarter is finished; the full-year forecast is the company's own view of what comes next, and it just went down. A beat on a closed quarter rarely outweighs a cut to the year ahead.

  5. The situationMonths after economic activity peaked, the National Bureau of Economic Research's dating committee announces that a recession began the previous spring. Stocks rise that day.

    5Why did the announcement move stocks so little?
    Show the answer

    A: It dates a turn that already happened, and prices moved on the data as it came out. The NBER committee dates peaks and troughs after the fact, once the data allow it, which can be many months later. Prices had already reacted to the weak reports along the way. The official date adds a label, and little information the market lacked.

  6. The situationAn analyst at a brokerage upgrades a hypothetical company from hold to buy and raises the price target. The company itself has said nothing new. The stock opens 4% higher.

    6What has the upgrade added to the facts?
    Show the answer

    B: One analyst's view of the same public facts, which can fade once the opinion is in the price. An upgrade is an opinion. It can move the stock as clients act on it, and once that buying is done the price has to stand on the business itself. A target is a forecast by one person and carries no promise.

  7. The situationAn anonymous post claims a hypothetical company will be bought at a large premium. There is no company statement and no filing. The stock jumps from $10.00 to $11.50, a 15% gain, in an hour.

    7What is the main risk for someone buying at $11.50?
    Show the answer

    D: If the rumor is denied or never confirmed, the jump can vanish, and a return to $10.00 would cost about 13%. An unconfirmed rumor can disappear in a single denial. A fall from $11.50 back to $10.00 is $1.50, which is about 13% of the price paid. Until a company statement or filing appears, the rumor is the only thing holding the price up.

Readers also ask

What does priced in mean?

A piece of news is priced in when buyers and sellers already expected it and traded on that expectation before it was announced. The announcement then confirms what the price already reflects, so the stock barely moves. The move comes from the part of the news nobody saw coming.

Why do stocks sometimes fall on good news?

The price before the news reflected what traders expected, and good news can still fall short of that. A company can report a strong quarter and lower its outlook in the same release, or an economic report can be strong enough to make an interest rate cut less likely. Traders react to the gap between the news and the forecast.
