SOCIAL SENTIMENT

Last updated: 22 September 2025

Objective:

This prompt measures trends in investor sentiment from social media posts (mainy X and Reddit) on the specified stock.

Explanation:

Tracking social sentiment on stocks offers investors a valuable window into how retail and institutional communities perceive a company in real time, often surfacing narratives, risks, and catalysts well before they are fully reflected in traditional research or price action. This prompt systematically collects and analyzes social media posts mentioning a chosen stock, quantifies sentiment on a standardized 0–20 scale across multiple time periods, extracts recurring themes with examples, and distills the collective conversation into clear bull and bear summaries. By combining sentiment scoring, thematic insights, and visual chart outputs, it helps investors identify shifts in market psychology, detect emerging opportunities or risks, and better understand how online narratives might shape future stock performance.

This prompt is best run on a regular, scheduled basis against watchlist stocks to capture inflection points.

As always, be aware that models can make mistakes. At each step, examine the response and challenge information or conclusions that appear erroneous before proceeding to any subsequent steps. If in doubt use a second model with the same prompt to verify the information and generate challenge questions and answers (CoVe process) to correct interpretations of data.

Preferred Model(s):

GROK (this prompt is specifically optimized for Grok due to its real-time integration with social media posts on X which has a large community of professional investors).

Important Execution Notes:

  • Specify Ticker, Exchange and Company Name where indicated under “Inputs”

  • Specify the measurement time period (1 month, week or day or other). This is the rolling span over which posts will be examined and sentiment computed.

  • Specify the number of successive periods to look back over. Eg the default of 3 with a 1 month measurement period will measure sentiment in each of the past three successive months to examine trends.
