The market pages
Readings of the market as a whole: a sentiment gauge, Treasury yields, an AI spending monitor, the earnings calendar and the day's news — each built from public data and dated.
Market sentiment gauge
The gauge rebuilds a well-known fear-and-greed reading from public data, on a scale from 0 (extreme fear) to 100 (extreme greed). It has seven factors, and says how close each one is to the original:
| Factor | How it is built here |
|---|---|
| Market momentum | Reproduced as defined |
| Market volatility | Reproduced as defined |
| Safe-haven demand | Reproduced as defined |
| Junk bond demand | A proxy from public prices |
| Stock price strength | A proxy, from the covered stocks |
| Stock price breadth | A proxy, from the covered stocks |
| Put and call options | Left out: the data behind it is not public |
The missing factor is shown as missing, never filled in. The history is recomputed every night.
Treasury yields
Treasury yields puts the 10-year yield first, because it is the starting point of every discount rate on the site, then lists all eleven maturities of the Treasury's daily par yield curve and answers four questions about the curve's shape. The 10-year it shows is the same number the valuations read that night.
AI bubble monitor
The monitor tracks thirteen indicators in five groups — spending, funding, payback, suppliers and the market. Each is placed against its own history, and the groups are averaged into one 0–100 pressure reading. It says where each number sits against its past; it never says whether AI is a bubble, or what to do about it.
Earnings calendar
The calendar shows one week as seven columns, each day's companies largest first, above a size floor you can change. Every week also has an address of its own for sharing.
News
Market news is the day's company news and 8-K filings, sorted by a classifier into key events and grouped so one company's day reads as one line. It updates every minute during US trading hours. The classifications are a trial and can be wrong; the headlines are their publishers', linked to the source. A stock's News tab is the same feed narrowed to one company.
Status
The status page shows whether the site and the API are answering, how current each dataset is, and how the scheduled runs went.
