2023 StockTwits S-Score Open-to-Close Quintiles
Context Analytics (CA) is the leader in processing and structuring textual data for sentiment analysis. CA ingests data from a variety of sources including StockTwits, a social media platform for investors and traders to share ideas about the market or securities. CA grades the sentiment from StockTwits messages on a scale of -1.000 to 1.000, aggregates them over a 24-hour period, and compares it to a historical baseline of 20 days to create S-Factors. The S-Factor feed is one of Context Analytics' longest-running products and includes the S-Score, which is a description of how positive or negative sentiment is by security.
S-Score is calculated by security and gives a cross-sectional view of Social Sentiment without bias towards message volume because the security’s sentiment is being compared to its historical baseline.
Securities with extremely positive sentiment we expect to outperform the market, while with securities with extremely negative sentiment, we expect to underperform.
We ran a quintiles test on this data, bucketing securities daily into 5 groups based on their S-Score at 9:10 am ET (20 minutes before market open). Quintile 5 represents the top 20% of S-Scores each day, Quintile 4 the next highest 20%, and so forth until Quintile 1 contains the lowest 20% of S-Scores each day.
We calculated the daily Open-to-Close returns for each security. Securities within each quintile are equally weighted to create daily quintile returns and then cumulated over time. The graph below shows the cumulative return of S-Score quintiles since the beginning of 2023.
The charts above clearly demonstrate a pattern between the S-Score and the subsequent return period. When the S-Score is high, meaning sentiment on StockTwits is more positive than normal, then the stock outperforms its peers. When the S-Score is low, it underperforms. There is a significant spread between Quintile 5 and Quintile 1 which generates a good Long/Short strategy. Based on the average count of each quintile, these graphs include the returns of over 2000 securities each day.
