How the score works

A headline's tone is not a forecast of the share price. Read the headlines themselves before acting on an average.

  1. Which headlines count

    Headlines come from the GDELT global news feed from 2019-09-23 on. A headline counts only when a model judges it to be about Hyliion Holdings Corp., not a passing mention.

  2. How each headline is scored

    The model calls each headline positive, neutral or negative news for the company. A period's tone is the share of positive minus negative headlines, from -100 (all negative) to +100 (all positive).

  3. When a headline counts

    Headlines published by 9:15 a.m. New York time belong to that day's session. Later and weekend headlines move to the next trading session.

  4. Repeated stories

    When several outlets carry the same headline, it counts once per session.
