The Wall Street Thematic Index (WSTI) tracks in real time the evolution of discussion topics among Wall Street professionals across 20 different market themes.

Using the buttons in the top-right corner of the dashboard, users can choose between viewing raw data — representing the daily number of occurrences of a given theme — or normalized data, which corresponds to the raw count weighted by the average number of messages. The normalized view is particularly useful for identifying underlying discussion trends, independently of daily fluctuations in total message volume, which are multifactorial.

As the data is updated in real time and changes throughout the day, each daily data point becomes final only at midnight (Paris time). Above the main chart, several buttons allow users to switch between predefined timeframes (1M, 6M, 1Y, 3Y, 5Y, and 10Y) or over a custom period using the calendar tool. The CSV export button, located in the top-right corner of the dashboard, only allows exporting the historical daily data currently displayed on the main chart.

The Topics & Entities chart allows users to visualize, for one or several selected themes, the top five unique keywords most frequently mentioned in discussions among Wall Street professionals.

For four specific themes  (Monetary Policy, Corporate Activity, Armed Conflicts, and Politics) it is also possible to view the top five entities (either individuals or organizations) most frequently cited in these discussions. When combined with the custom period selection tool, this feature makes it possible to explore which topics or entities dominated professional discussions at any given point in time.

The Associated Themes table allows users to visualize, for one or several selected themes, the eight themes most closely associated with them within professional discussions. It displays the exact count of each theme over a given period, as well as the correlation between the selected theme(s) and other related topics.

This feature provides valuable analytical insight into how market narratives and discussion topics evolve together, helping to identify co-movements, thematic clusters, or shifts in professional focus across time.

The WSTI World Map allows users to visualize the geographical associations of the selected theme(s). In other words, the map shows which countries, regions, or continents are most frequently linked to discussions among Wall Street professionals for a given topic.

For example, in the tweet “The New York Fed has revised down its growth projections for the U.S. domestic market,” the theme Growth & Business Cycle would be geographically associated with North America. However, the WSTI World Map does not display the geographical origin of the community panel members.
