Offbeat data
We pull free public numbers most investors skip: box prices, TSA lines, FDA reports, developer downloads.
Which way it leans
Green or red shows if the number rose or fell vs its recent past. We label that a tailwind or headwind for the company.
Why it matters
Every signal says, in plain English, how it connects to the business and the usual time frame: weeks to a quarter.

Education only. Not financial advice. These are clues from public data, not predictions or buy/sell calls.
Pick a stock
Curated stocks get deep custom signals. You can also look up any US ticker for a lighter pack (price, news, Wikipedia, Hacker News, SEC inventory).
Green and red track whether the data moved up or down vs its recent baseline. Separate Tailwind / Headwind badges say whether that move looks favorable or unfavorable for the company (some signals flip — e.g. more inventory can be a headwind even when the number is up).
Track record
Did the leans play out?
We log every stock's lean and check what the price did 2 weeks, 1 month, and 1 quarter later, against the S&P 500 too.

The strangest signals, once a week
Every Monday: the 3 to 5 oddest moves in our data (owner complaints, box prices, developer chatter…), one story explained in plain English, and our honest track record. No stock tips, ever.
How it works
Collect
A scheduled job pulls fresh numbers from public sources like the St. Louis Fed, the SEC, the FDA, the TSA, Wikipedia, and the GDELT news index. No logins, no paywalls, no scraping where it isn't allowed.
Compare
Each signal is compared with its own recent past (last 28 days vs the 28 before, or this year vs last year). Small moves inside a noise band are called neutral.
Explain
Every card says what the data is, why it might matter for that company, and what it's showing right now, written from the actual numbers. If a source fails, we say so instead of guessing.
Scout finds
A scheduled correlation scout scans free public series against curated stock prices (Tiingo) and ranks economically motivated pairings. Top hits below — correlation is not causation, and multiple testing is a real risk. Full method on the how it works page.
Same rule as the rest of the site: green/red track whether the public number moved up or down vs its recent baseline — not a buy/sell tip.

Signals we'd love to add
Some of these started as ideas. Where we found a free, legal, frequent public source, we wired a live proxy into a curated stock (linked below). The rest stay labeled ideas — we never invent numbers.
