Cross-Community Sentiment Convergence (CCSC)

Shows how strongly different Reddit communities agree on a ticker's direction.

Research Use Disclosure

What it measures

CCSC answers a simple question: are different communities seeing the same thing at the same time?

If many independent communities are all leaning bullish, or all leaning bearish, CCSC rises. If they disagree, CCSC falls.

This is important because broad agreement across separate communities is harder to fake than activity in just one place.

Inputs

CCSC uses three ingredients:

  • Daily sentiment per community for the ticker.
  • How trustworthy each community is in the Rebuzz system.
  • Which communities belong to different independent groups.

How it is computed

  1. Each community's sentiment is weighted by:

    • Community trust score.
    • Discussion volume (with diminishing returns, so very large threads do not dominate).

  2. Rebuzz computes:

    • A weighted sentiment for each independent community group.
    • An overall weighted sentiment across all groups.

  3. Rebuzz measures agreement by comparing each group's sentiment distribution to the overall distribution using KL divergence (a standard distance measure between distributions).

  4. Two outputs are produced:

    • Direction score on a 0 to 1 scale (below 0.5 is net bearish, above 0.5 is net bullish).
    • Confidence score that increases when:
      • Group-level agreement is tighter.
      • More independent groups are actually reporting.

Output + interpretation

  • Around 0.5: mixed or neutral direction.
  • Closer to 1.0: stronger bullish agreement.
  • Closer to 0.0: stronger bearish agreement.

Confidence is separate from direction. A ticker can look bullish but still have low confidence if only a small number of independent groups are active.

Edge cases/default behavior

If there is not enough usable data, CCSC returns safe defaults instead of forcing a noisy signal.

  • No usable signals or no cluster context: neutral direction (0.5) and zero confidence.
  • Communities without valid sentiment are ignored.
  • Communities that are not assigned to a group are excluded from the agreement calculation.

How Rebuzz uses it

CCSC is recalculated daily for active tickers.

It is one of the four core components of the final Rebuzz score, and its confidence is the primary confidence anchor for the composite signal.
