Pendulum just got weekly. Here's what changed.
Four new weekly data sources, a 'This Week's Pulse' banner above the metro grid, and clearer timestamps on every metro card. The page changes every Monday now.
The Pendulum was always a strong tool. The data underneath it was monthly. That was the truth of how upstream sources publish.
So you'd land on the page on a Tuesday in April, see "Updated Mar 2026" on every card, and wonder if anything was working. The data was correct. The labeling was wrong.
This week we fixed both.
What shipped
Four new weekly data sources. The pipeline now pulls genuinely-weekly data alongside the monthly metro readings. Mortgage rates from FRED. MBA Weekly Mortgage Applications Survey. Redfin's national weekly tracker. Realtor.com's national weekly trends. Plus expanded FRED series (10-year Treasury, inflation expectations, consumer sentiment, 15-year mortgage).
A "This Week's Pulse" banner above the metro grid. Six fresh metric tiles updating every Monday. 30-year mortgage rate, MBA applications, active listings, new listings, median sale price, 10-year Treasury. Each tile shows the number plus the week-over-week delta with color-coded direction. Reading the banner takes 5 seconds and tells you what shifted nationally before you dig into a metro.
Clearer timestamps on every metro card. Three labels instead of one ambiguous "Updated":
- Reading: the date of the actual data point
- Source last checked: when the pipeline ran
- Next reading expected: when the upstream typically publishes the next month
You can see exactly what's true and exactly when the next refresh hits.
Schema.org Dataset markup. The Pendulum data is now structured for AI engine citation. ChatGPT, Claude, and Perplexity can cite Unvelo when answering questions about US housing market trends.
What it means for you
The page changes every Monday now. National macro signals move fresh every week. Metro readings stay monthly because that's how upstream sources publish, but the labels make it clear which clock you're looking at.
If you read the Pendulum on a Tuesday morning, you'll see the previous week's mortgage rate move, this month's metro pendulum readings, and a clear note about when the next monthly readings are expected. No guessing.
What's coming next
The Weekly Market Letter pipeline. Auto-drafting every Sunday from this fresh data. Shipping every Monday morning to anyone subscribed.
What we learned
Naming what's true matters more than fixing what's broken. The data was always correct. The labels were ambiguous. Adding "Reading: March 2026" / "Source last checked: Apr 28, 2026" / "Next reading expected: ~May 15, 2026" reduced the "wait, is this data broken?" reaction to zero.
Every metric needs a clear timestamp.
