New home sales: Census contract data, revisions and wide error bands

What the data describe

A new home sale is recorded when a sales contract is signed or a deposit is accepted, even if construction has not started. That makes the series more timely than existing home sales, which count closings. It also makes it sensitive to builder incentives, such as mortgage rate buydowns, that can pull contracts forward.

Because the sample is small relative to the volatility of monthly sales, Census publishes a confidence interval with each estimate. A large monthly change can fall inside it, meaning the data cannot say with confidence whether sales rose or fell.

Revisions and noise

• The previous months are revised in each report, often by amounts comparable to the headline change.
• Regional figures are even noisier than the national total.
• The months' supply of new homes reflects builders' inventory, including homes not yet started, which differs from the existing-home measure.
• Price medians move with the mix of homes and regions sold; they are not quality-adjusted.

Why futures react modestly

New home sales connect to construction activity, builder earnings and the rates cycle. A strong or weak print can move home-builder shares and, sometimes, Treasury futures, but the wide error band and large revisions lead most participants to discount a single month. Index futures typically react only when the release lines up with a broader growth concern.

Order flow at 10:00 a.m.

New home sales often share the 10:00 ET minute with other data, and their own contribution is hard to isolate. When they print alone, the book usually does not step back much beforehand, and a large headline change can produce a brief spike that retraces as participants look at the revisions. On the footprint, that looks like a release bar with a long wick and heavy volume on the side opposite to the spike near its extreme.

A practical way to handle noisy releases is to define in advance what would count as a reaction: a close outside the opening range, or follow-through volume beyond the release bar. Anything less is treated as noise.

In Senzoukria

Rows whose name contains new home sales are described in the News calendar as “Housing demand — rate-sensitive sector.” Housing rows are often rated medium or low by the source; widen the Impact filter to see them.

Big Trades draws large executions as bubbles with a default minimum trade size of 50 and a 100 ms merge window; on a quiet release, the absence of large bubbles around 9:00 CT is itself a sign that size did not trade on the number.
