Signal or Static? A Stock Market News Quiz

Each stock market news quiz question gives you one headline about a hypothetical company or the economy. Decide whether it changes the outlook, and say what would have to be true for it to count.

What it tests

Whether you can tell a headline that changes a company's earnings outlook from one that is mostly noise, and say what would make it matter.

Does the headline you just read change what the company will earn? That is the question behind every one below. A useful headline changes the forecast. It moves the numbers for sales, costs or cash over the next few years, and those numbers are what a share price is built on, whatever the stock does on the day the headline lands. A noisy one moves the price for a day and leaves the forecast where it was, and if you trade on it you pay the spread and the stress for nothing.

What noise costs

Trading on static has a price. Say you sell 200 shares at $50 on a rumor, nothing comes of it, and you buy them back two days later at $51 because the reason you sold has gone away while the stock kept rising without you. That is $200 gone. The spread comes on top.

A worked example

Take a headline that does count. A hypothetical supplier has $400 million of annual revenue. It loses a customer worth 15% of that.

That is a new number for every forecast. Compare a headline that the company has a new logo. Nothing in the sum moves.

How to work through it

Read each headline and ask one thing. What would have to be true for this to change the earnings forecast? If you can name it and it has happened, call it signal. If it has not happened yet, the headline is static for now, and the condition you named goes on your watchlist as the thing that would change your answer when it shows up in a filing, a release or the next earnings call. Guidance cuts are the plainest case. How stocks react when a company cuts guidance shows what follows. An earnings pre-announcement is the version that arrives before the report.

When you get one wrong

A wrong answer usually means you reacted to the size of the headline. A large figure pulls the eye. Go back to the why line. Find the condition it names and ask whether the headline met it. Economic numbers work the same way, since a release that lands on the forecast confirms what prices already reflected while a large miss in either direction forces traders to reprice rates, earnings and risk all at once; reading an economic calendar shows where the forecast column sits. The same judgment, applied to the whole market, is the subject of Risk-On, Risk-Off or Sit Tight?

The questions

  1. The situationHeadline: a hypothetical parts maker cuts its full-year revenue guidance from $2.0 billion to $1.8 billion, citing slower orders from its largest customers.

    1Signal or static?
    Show the answer

    B: Signal: expected revenue fell by 10%. A guidance cut changes the numbers analysts use. The drop from $2.0 billion to $1.8 billion is $200 million, or 10% of the old figure, and it comes from management, the people with the best view of orders. For it to be noise, the slowdown would have to be a one-quarter blip that the company itself does not expect.

  2. The situationHeadline: an analyst raises the price target on a hypothetical restaurant chain from $50 to $55. The rating stays the same and the analyst's earnings estimates are unchanged. The stock already trades at $54.

    2Signal or static?
    Show the answer

    C: Static: nothing about the business changed. The target moved while the earnings estimates stayed put, so the analyst applied a higher multiple to the same profit, close to where the stock already sits. It would matter if the estimates behind it rose, because that would be new information about sales or margins.

  3. The situationHeadline: an unsourced social media post says a hypothetical cloud company is in takeover talks. The company declines to comment. No filing or statement has appeared.

    3Signal or static?
    Show the answer

    A: Static until something confirms it. A rumor with no source is static. It becomes signal when a company statement, a filing or a named report confirms talks, because only then can you weigh a price and a likelihood. Companies decline to comment on rumors as a matter of routine, so the silence tells you little.

  4. The situationHeadline: a hypothetical packaging company takes a $40 million restructuring charge to close one plant. Excluding the charge, EPS matched consensus, and full-year guidance is unchanged.

    4Signal or static for the outlook?
    Show the answer

    A: Static: the charge is a one-off and guidance held. One-off charges hit reported earnings once. Guidance and underlying EPS did not move, so the forecast for the next few years is about the same. It would matter if the company booked a restructuring charge nearly every year, since repeat charges are a real cost of running the business.

  5. The situationHeadline: a hypothetical regional retailer will be added to a major stock index at the next rebalance. Funds that track the index will need to buy its shares.

    5Does this change the company's earnings outlook?
    Show the answer

    C: No: it changes demand for the shares, while sales and costs stay the same. Index inclusion moves shares between owners around the rebalance date, and it says nothing about what the company will sell or spend. It would matter for the outlook only if membership changed the business itself, such as lowering its cost of raising capital for a large planned expansion.

  6. The situationHeadline: the chief financial officer of a hypothetical medical supplier leaves, effective immediately, two weeks before the quarter ends. The company names an interim CFO and reaffirms guidance in the same release.

    6How should you treat it?
    Show the answer

    B: As a flag to check: let the next filing and guidance decide. An executive departure is a question, and the answer comes later. It becomes signal if the next report brings a guidance cut, a delayed filing or a restatement. Watch for an earnings pre-announcement, which is how bad news in the same quarter usually reaches the market early.

  7. The situationHeadline: in a hypothetical month, the monthly jobs report shows 150,000 jobs added against a forecast of 150,000, and the unemployment rate is unchanged.

    7Signal or static for stocks?
    Show the answer

    D: Static: the number matched the forecast. A release in line with the forecast is mostly priced in, because the forecast was already in the market. The surprise is what moves prices. It would matter if the revisions to earlier months were large, or if the wage figures in the same release came in far from expectations.

People also ask

How do you know if stock news is important?

Ask whether it changes what the company will earn or how much cash it will produce over the next few years. A guidance cut, a lost customer or a confirmed deal usually does. A price target change, a rumor with no source or an economic number that matches the forecast usually does not, unless it arrives with new information.

Should you trade on analyst price target changes?

A target change on its own adds little, because the analyst is often catching up to a price that already moved. Look at whether the earnings estimates behind the target changed. A higher estimate is new information about the business; a higher target on the same estimate is mostly a new multiple.
