The National Association of Realtors releases its September existing home sales report at 10:00am ET today, and the conditions surrounding it are almost as important as the number itself. Monday, October 12 is a regular trading day for U.S. equity markets, but the bond market is closed for Columbus Day, following the recommendation of the Securities Industry and Financial Markets Association. That split matters for anyone trying to read today’s reaction in homebuilder stocks.
The closure of the cash bond market removes the main reference point for rates, so Treasury futures, the dollar, and equities may move on thinner volumes than usual, raising the risk of exaggerated swings on any headline. Fewer institutional participants actively trading means lower volumes, and even relatively modest flows can be enough to sometimes trigger exaggerated price swings. In plain terms: whatever homebuilder stocks do between 10am and 4pm today, size it by at least a third before drawing a conclusion.
The housing data itself, separate from today’s thin-trading distortion, tells a consistent story. Existing home sales fell 2% month over month in August to a 3.98 million annual rate, down 1.2% year over year, with inventory rising to 1.62 million units and months of supply reaching 4.9. NAR noted it was the first time since November 2019 that inventory topped 1.6 million units. More supply with fewer buyers is not a balanced market. It is a market where pricing power is eroding.
The forward indicators are worse than the backward-looking closings. Newly pending sales, a forward-looking indicator of future closed sales, fell 8.5% as mortgage rates reached their highest level since November 2023. Zillow noted the September drop was the largest annual decrease in that series since September 2023. Among 50 large metropolitan areas, the biggest year-over-year declines in pending sales occurred in Louisville, Cleveland, and Charlotte, each posting double-digit drops. Only three of those 50 metros showed nonnegative year-over-year changes: Hartford was flat, Milwaukee rose 0.8%, and Austin gained 6%.
Pending sales lead closed sales by roughly two months, which means the 8.5% contraction in September contracts is the number the October and November NAR reports will have to absorb. Zillow chief economist Mischa Fisher said renting remains a compelling option for households not ready to buy, and Zillow expects sales to run lower than a year ago through the fourth quarter.
The cost arithmetic explains the reluctance. The 30-year fixed-rate mortgage averaged 7.40% as of October 8, rising to its highest level since November 2023. That is up about 1.10 percentage points from roughly 6.30% a year earlier. A monthly mortgage payment on a typical home is now about 0.9% lower than a year ago, assuming a 20% down payment and excluding taxes and insurance.
Where this shows up most directly is in the large public homebuilders. Lennar is down about 22% in 2026. Rising mortgage rates are pressuring homebuilder stocks broadly, though analysts still cite structural housing demand of around five million units as a reason for upside in D.R. Horton, PulteGroup, and Lennar. D.R. Horton reports fiscal fourth-quarter earnings on October 29, and NVR follows around October 22, so both are heading into results with September’s deteriorating contract data as the backdrop. NVR’s land-light model gives it more balance sheet insulation in a downturn; DHI and LEN are more directly exposed to rate-driven demand swings at the entry-level end of the market.
The bearish case is straightforward: seven consecutive weeks of rising rates, the largest pending-sales drop in three years, and a months-supply ratio at a decade-plus high. The counterargument is that structural underbuilding and demographic demand have not disappeared, and Zillow itself noted it is not out of the question that rates could decline as rapidly as they rose, which would bring buyers and sellers back; the question is whether they would wait until spring.
Watch the 10-year Treasury when bond trading resumes Tuesday morning. If yields push past 5.30%, the pending-sales contraction currently showing in September data becomes the floor, not the ceiling, for what the October and November reports will show. The equity reaction to today’s 10am release, whatever it is, reflects a market without its primary rate anchor. Read it that way.
