Daily Investment Research Email with Olostep, OpenAI, and Gmail

This n8n template researches a stock watchlist with Olostep, turns the results into a concise OpenAI-generated investment research report, converts the report into a styled HTML email, and sends it with Gmail.

It can run manually for testing or automatically at weekday US market open.

This workflow is for research automation only. It does not provide financial advice, price targets, or buy/sell/hold recommendations.

What This Workflow Does

Runs at 9:30 AM US Eastern time on weekdays, or manually. Reads a comma-separated stock watchlist. Builds one investment research query per ticker. Uses Olostep to search for public investment sources. Combines the ticker results into one watchlist payload. Uses OpenAI to create one Markdown report for the full watchlist. Converts the report into a styled HTML email. Sends the final report through Gmail.

Example Use Case

An investor or analyst wants a daily pre-work research digest for a stock watchlist such as MSFT,NVDA,AAPL. Instead of manually searching filings, investor relations pages, earnings updates, and market news every morning, this workflow gathers public source results, summarizes opportunity signals and risk signals, and sends one structured HTML email for review.

Customization Ideas

Add more tickers to the watchlist. Change the email recipient list. Adjust the report prompt for a different research style. Add a market-calendar step to skip exchange holidays. Replace Gmail with another email provider supported by n8n.
