1.1 Workflow description

Title: Analyze stocks in Warren Buffett style from Telegram with OpenAI and Gmail
Workflow name: Analyze stocks in Warren Buffett style from Telegram with OpenAI and Gmail

This workflow turns a simple Telegram message into a full stock research report inspired by Warren Buffett’s value investing approach. A user sends a ticker symbol such as AAPL, MSFT, or AMZN, and the workflow validates the input, runs AI-powered research, performs discounted cash flow calculations, and sends a polished HTML report to Gmail with a final verdict.

It is designed as a reusable finance analysis template for creators, developers, and automation builders who want to combine Telegram, AI agents, live research, and email delivery in one workflow. Templates in n8n are intended to help users learn, reuse best practices, and quickly adapt a workflow to their own setup, so this version is structured to be easy to follow and reconfigure after import.

What this workflow does

Receives a stock ticker from Telegram and cleans the input before processing.
Validates the ticker format and stops invalid requests early with a helpful reply.
Uses an AI agent to generate a Buffett-style investment analysis.
Uses SerpAPI for live company and market research.
Uses a calculator tool for DCF and margin-of-safety math.
Sends the final HTML report to Gmail and confirms completion in Telegram.

Setup instructions

Import the workflow into n8n and reconnect your credentials for Telegram, OpenAI, SerpAPI, and Gmail. n8n templates are designed to be imported and then configured in the user’s own environment.
Open the Extract Ticker, Chat ID & Email node and replace [email protected] with your destination email address.
Create or connect your Telegram bot credentials, then test by sending a stock ticker like AAPL or MSFT.
Connect your Gmail OAuth2 account so the workflow can send the HTML report email.
Activate the workflow and run a live test from Telegram.

Requirements

Telegram Bot API credentials
OpenAI API credentials
SerpAPI credentials
Gmail OAuth2 credentials

Send portfolio risk reports with Google Sheets, GPT-4o-mini and Gmail

## Quick Overview This workflow receives a portfolio via webhook (uploaded CSV or Google Sheets), calculates allocation and concentration risk metrics, generates an OpenAI HTML risk report, emails it through Gmail, and returns a JSON API response with the report status. ## How it works 1. Receives a POST webhook request containing a portfolio source type plus user name and email. 2. Loads holdings either by decoding an uploaded base64 CSV into rows or by reading rows from Google Sheets. 3. Combines all holdings into a single dataset and attaches user and source metadata. 4. Calculates portfolio totals, position weights, sector and asset-class breakdowns, concentration flags, top gainers/losers, and an overall risk score and label. 5. If the portfolio is valid, sends the computed metrics to OpenAI to generate a client-ready HTML risk narrative. 6. Builds a formatted HTML email that includes the AI analysis plus sector and top-holdings tables, then sends it to the user via Gmail and returns a success JSON response. 7. If the portfolio is empty or invalid, emails a failure notice via Gmail (when an email is provided) and returns a 422 JSON error response. ## Setup 1. Create and connect credentials for Google Sheets OAuth2, OpenAI, and Gmail OAuth2. 2. Configure the webhook endpoint by copying the production URL and sending POST requests to the /portfolio-analyze path. 3. For CSV submissions, include base64 CSV content in body.fileData (or body.csvBase64/body.file) and ensure the columns include ticker, company, sector, quantity, avg_buy_price, current_price, and asset_class. 4. For Google Sheets submissions, update the spreadsheet document ID and sheet (gid) to the holdings table you want to analyze. 5. Ensure the request includes userEmail (body, query, or x-user-email header) so the workflow can deliver the report or validation error message.

Analyze commodity portfolio diversification with Sheets, Gemini, and Gmail

## Quick Overview This workflow reads a gold/silver/oil portfolio from Google Sheets, pulls current commodity prices and a recent gold trend from GoldAPI, EIA, and Twelve Data, calculates allocation and HHI concentration risk, generates a Gemini analysis, and emails an HTML diversification report via Gmail. ## How it works 1. Starts manually and loads configuration values, then reads your portfolio holdings from Google Sheets. 2. Fetches real-time gold and silver prices in INR from GoldAPI, retrieves crude oil prices in USD from the EIA API, and converts oil prices to INR. 3. Pulls the last two daily closes for GLD from Twelve Data and compares them to label the gold market trend as UP or DOWN. 4. Aggregates the latest commodity prices and trend data, then calculates portfolio allocation percentages and an HHI concentration score from the Google Sheets holdings. 5. Sends the allocation, HHI score, and gold trend to Google Gemini to generate a structured risk assessment, rebalancing recommendations, trend impact, and a verdict. 6. Parses Gemini’s response into dedicated fields, builds a formatted HTML report with prices, allocations, risks, recommendations, and verdict, and sends it to the configured recipient via Gmail. ## Setup 1. Add API keys for GoldAPI, the U.S. EIA API, and Twelve Data in the configuration step (and confirm the USD-to-INR conversion rate is correct for your needs). 2. Connect your Google Sheets account, then update the spreadsheet and sheet tab to a portfolio table that includes commodity_name and buy_price for gold, silver, and oil. 3. Connect your Google Gemini (PaLM) API credential and ensure the selected model is available in your account. 4. Connect your Gmail OAuth2 credential and set the recipient email address used for the report delivery.

Log gold and silver prices and email Groq insights with Google Sheets

## Quick Overview This workflow manually logs daily Gold and Silver prices from GoldAPI into Google Sheets, summarizes historical monthly averages, generates seasonal insights with Groq (LLM), builds QuickChart bar charts, and emails a formatted report via Gmail. ## How it works 1. Starts manually and loads a two-item asset list (Gold/XAU and Silver/XAG) to process in a loop. 2. For each commodity, calls the GoldAPI endpoint to fetch the latest INR price and converts it into a per-10g value with date and month fields. 3. Checks Google Sheets for an existing row for the same commodity and date, keeps the higher of the two prices, and appends or updates the row in the historical sheet. 4. Reads the full historical dataset from Google Sheets and calculates monthly average, minimum, and maximum prices grouped by month and commodity. 5. Formats the monthly averages into a text block and sends it to a Groq-hosted chat model to generate a structured JSON insight summary for gold, silver, and the overall trend. 6. Creates QuickChart URLs for separate Gold and Silver monthly-average bar charts and emails the AI summary and chart images using Gmail. ## Setup 1. Add a GoldAPI key and set it in the HTTP request header (x-access-token) for the GoldAPI call. 2. Connect Google Sheets OAuth credentials and select the target spreadsheet and sheet tab where rows are stored (e.g., the 04_HistoricalData sheet). 3. Ensure the sheet has columns for ID, Date, Month, Price, and Commodity, and that ID is used as the upsert/matching key. 4. Add Groq API credentials for the Groq chat model used to generate the JSON insights. 5. Connect Gmail OAuth credentials and replace the placeholder recipient address ("RECEIVER MAIL ID") and subject as needed.
