The BubbleIndex
Every ticker gets a 0–100 BubbleIndex, computed at read time from four weighted factors:
v1 · YouTube-only. Made-for-kids content is excluded at ingestion.
Hype detection
A ticker is flagged ⚠ when its share of hype-classified mentions exceeds the dataset's 2.1% baseline, and only once it has enough mentions in the window to be statistically meaningful — a single hype-flagged video is never enough to trip the flag on its own.
The Hype Watch rail ranks flagged tickers by hype share weighted against mention volume, so a name with sustained hype across many mentions outranks a low-volume ticker having one lopsided week.
Bubble stages
Every ticker is placed into one of five stages each window, derived from 72-hour momentum relative to the 30-day baseline — not a subjective call.
- Emerging
- 72-hour momentum has ticked above the 30-day average — early signs of building conversation.
- Bubbling
- Momentum has surged — at least 1.5× recent activity versus baseline, with meaningful volume behind it.
- Boiling
- Surging momentum plus a hype spike or unusually wide coverage — the most intense stage.
- Cooling
- 72-hour momentum has fallen below 80% of the 30-day average — the conversation is fading.
- Flat
- Momentum is steady — no meaningful acceleration or decline this window.
