Thursday's Two-Stage Event Day: GDP and PCE at 8:30 a.m., Then Amazon and Intel Earnings

Quick Summary

On Thursday, October 29, the Bureau of Economic Analysis releases the preliminary estimate of third-quarter GDP and September personal income and outlays, including PCE price indexes. Hours later, Amazon and Intel report earnings after the close. This article defines the key terms (SAAR, month-over-month versus year-over-year, core PCE, nowcast), lays out the most recent official readings, and explains in general terms how implied volatility can build ahead of scheduled events and fall afterward. It is educational and makes no prediction about direction.

Thursday, October 29 packs two rounds of scheduled uncertainty into one session. At 8:30 a.m. ET, the Bureau of Economic Analysis (BEA) is scheduled to release its advance estimate of third-quarter GDP along with September Personal Income and Outlays, which includes the PCE price indexes. After the close, Amazon and Intel are both scheduled to report earnings. Here is how to read each piece.

Stage one: GDP and PCE

GDP (gross domestic product) measures the total output of the U.S. economy. Headline GDP is quoted as a SAAR, a seasonally adjusted annual rate, meaning the quarterly change is annualized so quarters are comparable. The Q2 third estimate came in at +2.2%, up from 1.5% in the second estimate, per the BEA. Q1 was revised to 2.5%.

PCE (personal consumption expenditures) price indexes track inflation in what households buy. The Federal Reserve's longer-run inflation goal is defined in terms of PCE, which is why many economists watch it closely. Core PCE strips out food and energy, which swing a lot, to show the underlying trend.

Two terms trip up newcomers:

Month-over-month (m/m) compares to the prior month.
Year-over-year (y/y) compares to the same month a year earlier.

A reading can look tame on one basis and hot on the other.

For reference, the BEA's August report showed headline PCE up 0.3% m/m and 3.4% y/y, with core up 0.2% m/m and 3.0% y/y.

Expectations: handle with care

Formal survey consensus for these releases was hard to pin down in the sources we reviewed, so this article doesn't quote one. The Atlanta Fed's GDPNow tracker, a nowcast, showed 3.3% for Q3 growth when last updated on October 28. A nowcast is a model-based running estimate, not a survey of forecasters, so the two are not interchangeable. Check a live source on the morning of the release for current forecasts.

Where the Fed fits

The Federal Reserve's policy meeting runs October 27 and 28, with its statement scheduled for 2:00 p.m. ET on Wednesday. Whatever the decision, Thursday's data may arrive while markets are still digesting it. Inflation and growth readings feed expectations about the path of interest rates, and rate expectations influence how investors value stocks, especially those whose earnings are expected far in the future.

Stage two: earnings after the close

Amazon is scheduled to report after the close, with its call at 5:00 p.m. ET per the company, and Intel also reports after the close. A macro surprise at 8:30 a.m. can change the backdrop that earnings land in, but the two events are separate. Single-stock results can matter more or less than the macro numbers, depending on the stock.

How options pricing treats scheduled events

Implied volatility (IV) is the market's expectation of future price swings, embedded in option prices. When a known event is approaching, option prices covering the event date tend to carry extra premium, often called an event premium. After the event passes and the uncertainty resolves, that premium often deflates, a process traders call IV crush. The size of the drop varies, and it is not guaranteed.

Two practical points follow:

Options that expire right after an event cost more than options expiring just before it, all else equal, because they include the event.
Being right about direction is not always enough. If IV falls after the release, an option can lose value even when the underlying moves the way its holder hoped.

Risks to keep in view

Options can lose their entire premium. Some traders sell options to collect event premium. Losses on uncovered short options can be many times the premium received and, for short calls, can be unlimited, and assignment and margin requirements apply. Nothing here is a recommendation. The OCC's "Characteristics and Risks of Standardized Options" document explains these risks in detail. Data releases can also be revised, delayed, or interpreted in surprising ways, and a single day's reaction does not predict the next. Nothing about a calendar of events tells you which way prices will move.
