Sector Rotation Tracker & Alert System of Equity Market
Sector Rotation Tracker & Alert System of Equity Market This workflow automates the tracking of stock market sector rotation. It fetches a list of active stocks from Google Sheets, pulls their last 5 days of market data from Yahoo Finance and calculates momentum and sector strength using custom code. It then compares this current data against historical data to detect capital rotation signals. Finally, an AI Agent (powered by Groq's Llama-3 model) acts as a financial analyst to interpret the shifts and sends an automated Gmail alert if a high-confidence bullish trend is detected. Quick Implementation Steps Don't want to read the details? Follow these quick steps to get started: Connect Credentials: Authenticate your Google Sheets, Gmail and Groq API accounts in n8n. Setup Google Sheets: Create a Google Sheet with two tabs. "Sheet1" needs an active column set to true for stocks you want to track. "Sheet2" is used to store daily historic data. Update Sector Map: Open the Group By Sector code node and update the sectorMap with your specific stock symbols and their corresponding sectors. Configure Email: Open the Send Email Alert node and enter your destination email address. Test and Run: Click "Test Workflow" to ensure data flows correctly, then activate it to run on your schedule! What It Does The Stock Sector Rotation Tracker acts as your personal automated quantitative analyst. It starts by pulling a predefined watchlist of active stocks from a connected Google Sheet. Using Yahoo Finance's API, it retrieves the daily closing prices and trading volumes over the past 5 days for each stock. Once the raw data is gathered, a series of custom JavaScript nodes process the information. It calculates 1-day, 3-day and 5-day returns, assigns momentum scores and evaluates volume ratios. The stocks are then grouped into their respective market sectors (e.g., IT, Banking, Auto) to calculate an aggregate "Sector Strength Score." This score is compared against historical data saved from previous days to determine if money is rotating into or out of a specific sector. To add a layer of human-like intelligence, the compiled data is sent to an AI Agent powered by Groq. The AI acts as an institutional equity researcher, providing a concise summary, explaining the possible reasons for the market movement and assigning a trading bias (Bullish, Bearish or Neutral) along with a confidence score out of 10. If the AI identifies a strong bullish signal, a detailed email alert is instantly dispatched via Gmail. Who It's For Retail Investors & Day Traders** Looking for automated daily watchlists and momentum alerts without paying for expensive terminal subscriptions. Financial Analysts & Wealth Managers** Needing an automated way to track institutional capital flows and sector rotation over time. Quant Enthusiasts** Wanting a foundation to build custom algorithmic trading indicators using n8n and AI. Requirements to Use This Workflow To successfully run this workflow, you will need: An active n8n account (Cloud or Self-Hosted). A Google Account to access Google Sheets (for data storage) and Gmail (for sending alerts). A free Groq API key to power the Llama 3 AI model. A basic understanding of stock symbols (tickers) as used on Yahoo Finance (e.g., INFY.NS or AAPL). How It Works & Set Up Step 1: Prepare Your Google Sheets You need a Google Spreadsheet with two specific tabs. Tab 1 (Watchlist):** Must include columns for stock symbols and an active column (set to true or false). Tab 2 (Historic Data):** Must include columns for date, sector, sector_strength_score, trend, rotation_signal and score_change. Step 2: Configure Credentials in n8n Google Sheets & Gmail:** Set up OAuth2 credentials for your Google account. Connect these to the Google Sheets nodes and the final Gmail node. Groq API:* Generate an API key from the Groq console and add it to the *Insights from Model** node. Step 3: Update Stock and Sector Mappings Open the Group By Sector code node. Modify the sectorMap JavaScript object to match the stock symbols in your Google Sheet. For example, change "INFY.NS": "IT" to match your desired ticker and sector. Step 4: Review AI and Email Thresholds The workflow uses an If node named Check if Bullish. By default, it sends an email if the AI Action is exactly Bullish OR if the AI Confidence score is greater than 7. You can adjust these thresholds based on how strict you want your alerts to be. How To Customize Nodes Modify the Timeframe** In the Get stocks Data node, the Yahoo Finance URL ends with ?range=5d&interval=1d. You can change this to 1mo (1 month) or interval to 1wk (1 week) to track macro trends instead of short-term momentum. Tweak the Math Formula** The Calculate Stock Returns code node assigns weights to different days (e.g., 1-day return is weighted at 50%, 3-day at 30%). You can easily adjust these multipliers to fit your personal trading strategy. Change the AI Prompt** Open the Prepare AI Insights Prompt code node or the AI Analyzer agent node to rewrite the AI's instructions. You can ask it to adopt a different persona, like a conservative dividend investor, rather than a momentum trader. Add-ons Want to take this workflow to the next level? Here are a few ideas: Slack / Discord Integration** Replace or supplement the Gmail node with a Slack or Discord node to push alerts directly to a trading community channel. SMS Notifications** Add a Twilio node to get instant text messages when a high-confidence rotation signal fires. Multiple AI Perspectives** Add a secondary AI node (like OpenAI's GPT-4o or Anthropic's Claude 3.5) to analyze the same data, then use an IF node to only send an alert if both models agree on a Bullish trend. Use Case Examples Daily Morning Briefing Schedule the workflow to run 30 minutes before the market opens to get a fresh perspective on where capital moved the previous day. Swing Trading Assistant Use the automated "ROTATION_IN" signals to build a shortlist of swing trade opportunities before the broader market catches on. Portfolio Rebalancing Track sector strength over weeks or months to decide when to rebalance a long-term retirement portfolio from lagging sectors to leading ones. Institutional Capital Flow Tracking Identify "volume boosts" alongside price momentum to spot hidden institutional buying in specific market sectors. Educational Paper Trading Forward the AI insights to a journal or note-taking app (like Notion) to learn how data-driven momentum aligns with actual market performance over time. Troubleshooting Guide | Issue | Possible Cause | Solution | | :--- | :--- | :--- | | Yahoo Finance HTTP Request Fails | Rate limits or invalid ticker symbol. | Check that the symbols in your Google Sheet exactly match Yahoo Finance tickers (e.g., adding .NS for Indian stocks). Add a longer batching interval in the HTTP node settings. | | No Data Moving Past "Group By Sector" | sectorMap doesn't match incoming symbols. | Open the Group By Sector node and ensure the ticker names in your code exactly match the tickers coming from the API. | | AI Node Throws JSON Parse Error | The AI responded with conversational text instead of strict JSON. | The Parse AI Output node has a fallback to catch this, but you can improve reliability by emphasizing Respond ONLY in valid JSON format in the AI Agent's system prompt. | | Google Sheets Node "Cannot find sheet" | Document ID or Sheet ID mismatch. | Re-select your specific Spreadsheet and Worksheet directly from the dropdown menus inside the Google Sheets nodes. | | Emails Are Not Sending | The IF node condition is not being met or Gmail authentication expired. | Check the execution logs. If the AI is returning a confidence of 6, it won't send. Re-authenticate your Google account if the node shows an OAuth error. | Need Help?
