The Economic Releases That Move Markets

Why would every stock on your watchlist drop on a morning when the only news was an inflation reading one tenth of a point above forecast? The answer is in what that reading changes. Stock prices rest on expectations about interest rates and company profits, and a release that moves either expectation moves prices, sometimes by far more than the size of the number seems to justify.

What makes a release market moving

Sort releases with one test. Does the number change what investors expect the central bank to do with rates, or what they expect companies to earn? If it does either, it can move markets. If it does neither, it can print a wild number and pass almost unnoticed.

The releases that pass the test most often fall into a few families:

• Inflation: CPI and PCE.
• Jobs: payrolls, unemployment and wages.
• Spending: retail sales and personal spending.
• Business surveys: the PMIs.
• Central bank rate decisions.

CPI is the consumer price index and PCE the personal consumption expenditures price index, the two measures of what households pay, and the PMIs are purchasing managers’ indexes built from surveys of businesses about their orders, output, hiring and prices. Your calendar probably flags these with its top importance marker. That marker is a vendor’s judgment, so run the test yourself.

Rates and profits, the two channels

Inflation data works mostly through rates. A hot reading makes a rate cut less likely or a hike more likely, bond yields rise, and the rate investors use to discount a company’s future cash flows rises with them, which lowers what those cash flows are worth today even though nothing about the company changed overnight.

Spending and survey data work mostly through profits. They describe demand. Weak orders now become weak sales later.

Jobs data hits both. A strong report means more household income to spend, good for revenue, and more pressure on wages and prices, bad for rates. The same number can lift a retailer and sink a richly valued software stock on the same morning, which is why the market’s reaction to jobs data can look contradictory from month to month.

A release is judged against its forecast

The forecast column on your calendar is a consensus of economists’ estimates. By the time a release prints, prices already reflect something close to that forecast. What moves prices is the gap between the actual and the forecast.

A tenth of a point sounds like rounding. Kept up for a year, it leaves inflation more than a full point above what the central bank and the bond market had planned around, and that is the kind of gap that changes rate expectations for every stock at once.

Now take a minor series. Suppose a hypothetical regional factory survey was forecast at 5 and prints at minus 5. That’s a 10-point miss. It may barely register, because one region’s survey says little about national inflation or national profits, and bigger national reports arrive soon after to confirm or overrule it. Weigh the series before you weigh the miss.

Revisions and the detail under the headline

The headline is one line of a release. Many monthly reports also revise the prior month, and a jobs report that matches its forecast while last month is cut sharply carries a surprise the headline hides. The detail matters too. Core inflation strips out food and energy. Wage growth sits inside the jobs report. Traders often weigh those lines above the headline itself.

What it means for a single stock

For one holding, a release matters through whichever channel reaches that business. A bank, a homebuilder and a software company whose profits sit mostly in the future each feel a rate surprise differently. A retailer feels a spending surprise more than a utility does. Knowing which channel reaches each holding tells you which rows deserve attention before the open.

Weekly releases fill the gaps between the monthly ones, and initial jobless claims is the one to learn first. Business surveys have their own quirks, covered in the case for reading PMI new orders before the headline PMI. The economics hub has the wider reading list.

The rate channel reaches every stock at once, so the next lesson starts there, working through what interest rates do to stock valuations with a simple sum on a hypothetical company.
