Use case example: sector-wide sentiment impact of Trump 2.0 tariffs
Objective
Identify which sectors of the Russell 1000 are most negatively impacted by the potential return of Trump-era tariffs — and to what degree.
Why it matters
Policy changes like tariff reinstatements can have immediate, sector-specific implications. With Bigdata, you can:
Gauge sentiment at the company and sector level
Detect market-wide exposure to trade-related risk
Spot emerging signals from hundreds of thousands of filings, news articles, and reports
The solution with Bigdata.com
1. Run 1,000 parallel search queries. Each company in the Russell 1000 is queried using a combination of entity recognition and a custom similarity query: e.g., “Trump 2.0 tariffs impact”
2. Retrieve 1 million documents. In just under 4 minutes, Bigdata retrieves up to 1,000 relevant documents per company, covering:
Filings
Earnings call transcripts
Analyst notes
Real-time news reports
3. Compute sentiment at scale. Using Bigdata's chunk-level sentiment and relevance scores, a weighted sentiment score is calculated for every company and mapped across sectors.
4. Visualize the results. A custom bar chart highlights the sectors most negatively impacted by the proposed tariffs. For example:
Telecom
Consumer goods
Tech
These sectors had the highest share of companies with strongly negative sentiment (defined as below –0.45).
