Claude Cowork, Bigdata Plugin/5 minutes read
Portfolio Managers can now automate portfolio research with Claude Cowork and the Bigdata.com Plugin, a connector that gives Claude direct access to Bigdata’s Search engine and Knowledge graph. A single scheduled task runs every morning, identifies the top market-moving topics, assesses their impact on each holding, and delivers individual PDF briefs with inline attribution. The result: you open your laptop, launch Claude, and by the time you have your coffee the analysis is done. It is 6:45 AM. You open your laptop and launch Claude. That is all it takes. Within seconds, your scheduled Cowork task kicks off. While you make your coffee, check your messages, or get ready for the day, Claude is scanning the last 24 hours of financial news, identifying the five topics most likely to move markets today, cross-referencing each one against every company in your portfolio, scoring the potential impact, and generating a detailed PDF brief for each holding. By the time you sit back down, the analysis is waiting in a folder on your desktop.

Why does morning research take so long?

Every Portfolio Manager knows the routine. Markets open, and the first hour is a scramble: skimming headlines, checking overnight moves, trying to connect scattered data points to the positions that matter. The table below shows where that time typically goes:
Manual taskTime spent dailyAutomated equivalent
Scanning news for relevant topics30-45 minClaude Cowork searches via Bigdata search in seconds
Mapping topics to portfolio holdings20-30 minKnowledge graph resolution matches tickers to entities automatically
Drafting impact notes per company60-90 minPDF reports generated with inline source attribution
Updating tracking spreadsheets15-20 minSpreadsheet updated with scores and confidence levels
Total~2-3 hours~10 minutes (unattended)
The information is out there. The problem is that assembling it into something actionable takes too long when done manually, every single morning.

How does Claude Cowork automate portfolio research on a schedule?

Claude Cowork lets you define tasks that run automatically when you open the application. Combine that with the Bigdata.com Plugin, which bundles the Bigdata MCP connector and the Financial Research Analyst skill, and you get an autonomous research assistant that delivers a structured portfolio impact analysis every morning. Here is what the workflow produces:
OutputDescription
Top 5 market-moving topicsIdentified from the last 24 hours using Bigdata’s search engine, which indexes thousands of premium financial sources
Impact assessment per companyEach topic scored for relevance, direction, and confidence against every holding in your portfolio
Individual PDF reportsOne brief per company with detailed analysis and inline attribution linking back to original documents
Updated portfolio spreadsheetA single summary view with impact scores, confidence levels, and topic mappings
Scheduled task running

What does the setup look like?

The entire configuration takes minutes. You provide an Excel file listing the companies in your portfolio, just the ticker and the company name. Claude handles the rest. Portfolio template Once the scheduled task runs, it creates a timestamped folder containing a PDF brief for each company and an updated copy of your spreadsheet with impact scores, confidence levels, and topic mappings filled in. Portfolio analysed Under the hood, Claude uses the Bigdata knowledge graph to resolve each ticker to its canonical entity via find_companies, then runs targeted searches through the Bigdata search service to retrieve the most relevant news for each holding. Every claim in the PDF report links back to its source through inline attribution, so you can verify any insight in seconds. These are some examples of the daily briefs generated by the workflow:

How does this change the Portfolio Manager’s morning?

The goal is not to replace the Portfolio Manager. It is to eliminate the 2-3 hours of repetitive assembly work so you can focus on what drives returns: interpreting the data, forming a view, and making decisions. With this workflow, your morning changes. Instead of scrambling to catch up, you start with a clear picture of what matters for your book today. You can go deeper on the topics that need attention, ignore the noise, and move faster. The Bigdata search service ensures coverage across thousands of sources, and the knowledge graph ensures every company is correctly identified regardless of ticker format or exchange.
