There’s a housing boom going on in America as low mortgage rates, the accumulation of wealth, and the desire for more space has renters becoming buyers.

On Thursday, we learned that the pace of existing-home sales, or the sale of previously owned homes, jumped 7.0% from August to an annualized rate of 6.29 million units in September. While this number is down slightly from a year ago, it continues to hover at levels last seen during the housing boom 15 years ago.

All this activity has caused the inventory of homes for sale to tumble, which has spurred the construction of new homes.

In September, there were 712,000 single-family homes under construction, the highest level since 2007.

Not everyone’s trying to buy a house.1 There are plenty of us who can’t afford a house or are just more comfortable in our multi-family buildings.

And construction of multi-family units, like apartment buildings, is at its highest level since 1974.

Home-buying is, of course, contributing to all of this building.2

But the reason why there are so many homes being constructed simultaneously is related to something we’ve been hearing a lot of lately: delays caused by supply chain bottlenecks and labor shortages.

“Although demand and home sales remain strong, builders continue to grapple with ongoing supply chain disruptions and labor shortages that are delaying completion times and putting upward pressure on building material and home prices,” Chuck Fowke, chairman of the National Association of Home Builders, said on Monday.

When new construction paces with completions, these under construction numbers go sideways. However, when the pace of construction starts is elevated but it’s taking longer to complete construction, the number of units under construction piles up like what we’re witnessing now.

Because of supply chain issues and labor shortages, it’s taking a lot longer to complete the construction of a lot of single-family homes that have already been sold and a lot of apartment buildings that, once completed, will help ease surging rents.

All of this bears watching as the Federal Reserve plans to start dialing back its emergency monetary policy, which could send mortgage rates higher.

In case you missed it, here’s what I wrote last week:

• 88% of the stocks in the S&P 500 fell more than 10% from their highs this year. Why this is a win for index fund investors.

• Deflation might sound like it’d be good news since stuff is getting cheaper, but it would actually be very bad news.

• The supply chains are a mess, but it’s the effect of some incredibly bullish things happening in the economy.

Stocks set record highs: The S&P 500 gained 1.6% last week. On Thursday, it closed at a record high 4,549.78, the index’s 55th record high of the year. For more on stocks, check out 10 Truths About the Stock Market.

Why advertise what you can’t sell? Snapchat shares cratered after the social media giant announced disappointing third quarter results. The company, which makes money as an advertising platform, specifically stated that businesses were scaling back on ad spending because they don’t have enough stuff to sell.

Here’s what Snapchat chief business officer Jeremi Gorman said on Thursday: “We have heard from advertising partners across a wide variety of industries and geographies that they are facing headwinds in their business related to disruptions in global supply chains as well as labor shortages and increasing costs. In turn, we expect this to impact advertising demand in Q4 in particular as, in many cases, their businesses do not have the inventory or operational capacity to support incremental demand.“

Airlifting Crocs out of Vietnam: Crocs, like many other footwear and apparel makers, source goods from Vietnam – where COVID has disrupted manufacturing. Supply delivery delays have been amplified by congestion in the world’s ports, which has made shipping by boat a very slow process. So to get their ubiquitous clogs to customers, Crocs said it leaned into airfreight.

“We plan to invest approximately $75 million in airfreight ahead of our 2022 spring summer selling season,“ Crocs CFO Anne Mehlman said on Thursday.

Prices are going up: Here’s a sampling of headlines that emerged from last week’s corporate earnings announcements: “Chipotle earnings crush estimates as sales jump 22%, higher menu prices offset rising costs“ (CNBC); “Unilever, consumer goods giant behind Dove and Ben & Jerry, raises prices by 4%“ (ABC); and “Procter & Gamble to raise prices of more household goods as supply chain costs bite“ (FT).

… On one hand, nobody wants to hear that the prices of the stuff they buy are going up, especially when they’re going up faster than that raise you hope to get…

… On the other, these measures taken by big companies are why some argue that investing in stocks is a good hedge against inflation. Even as costs have been going up for big companies, analysts expect Q3 earnings for the S&P 500 to be up 33% from a year ago, with net profit margins fat at 12.5%.

Up the road

Corporate earnings: We’ll continue following quarterly earnings announcements. Companies announcing results next week include Facebook, 3M, UPS, GE, Google-parent Alphabet, Boeing, Coca-Cola, McDonald’s, GM, Ford, Caterpillar, Amazon, Apple, and Starbucks.

In light of the revelations in Snapchat’s earnings call, it’ll be illuminating to see what other unexpected consequences emerge amid these persistent supply chain issues.

1 I’m certainly not looking to buy a house. I grew up in multi-family complexes, so living in an apartment has always been very familiar to me. Though, we did eventually move into a single-family house, and it was lovely. It had a ton of space, which I was responsible for vacuuming every week. It had a front yard and a backyard with lots of grass, which I was responsible for mowing every couple of weeks. It was great.
