7 Ways to Build Investment Portfolio Tracker in Excel

Managing stocks and ETFs across accounts gets messy fast, and guessing your gains or sector exposure is no way to invest. Centralize everything, track real performance, and get notified when something needs your attention instead of reacting late. This guide walks you through pulling live stock prices, calculating gains and losses, monitoring sector exposure, and setting alerts for meaningful price changes. And here’s the thing: this comprehensive guide will show you how to build an investment portfolio tracker in Excel to monitor all your holdings in one place and send automated email alerts for significant market moves.

1. Design The Column Structure 

Open MS Excel and decide on the column structure based on the investment details you want to track. Fill in the header rows. I have used the structure below: 

A1: Symbol - Stock ticker (AAPL, MSFT, SPY) 
B1: Company Name - Full company/fund name 
C1: Asset Type - Stock, ETF, Bond, Crypto 
D1: Shares - Number of shares owned 
E1: Avg Cost - Average purchase price per share 
F1: Total Cost - Total investment amount 
G1: Current Price - Live market price (auto-updated) 
H1: Market Value - Current total value 
I1: Gain/Loss $ - Profit or loss in dollars 
J1: Gain/Loss % - Return percentage 
K1: Sector - Industry sector (Technology, Healthcare, etc.) 
L1: Notes - Purchase date, strategy notes

2. Fill in Sample Data 

Insert a sample of 20 diverse stock and ETF holdings across multiple sectors. Include technology stocks, financial services, healthcare, consumer goods, energy, and index ETFs to create a diversified portfolio. Leave Columns F through J empty initially, as they will be filled automatically with formulas in the upcoming steps. 

Sample Holdings: 

3. Getting Live Stock Prices 

Now we’ll set up automatic price feeds. Excel Desktop has multiple methods, but we’ll use the most reliable approach for consistent results. 

Method 1: Using Stock Data Types  

Follow the following steps below: 

1. Select ticker symbols in column A (A2:A21) 
2. Go to Data tab  
3. Click Stocks button 
4. Wait for conversion (10-15 seconds for all 20 stocks) 
5. Verifyy success by seeing a small icon next to each ticker 

Extract Current Price in Column G: 

Click cell G2 and enter this formula: =A2.Price 

This extracts the live current price from the Stock data type. Copy this formula down to G3:G21.

Method 2: Alternative Solution for Compatibility Issues 

Sometimes the “STOCK” Function in excel depends upon the latest version and geography. If Stock data types don’t work on your system, use this STOCKHISTORY function: 

Click cell G2 and enter: =INDEX(STOCKHISTORY(A2,TODAY()-1,TODAY()),1,5) 

This pulls the most recent closing price. Copy down to G3:G21. 

4. Building Smart Calculation Formulas 

Now we’ll add formulas to automatically calculate your investment performance. These formulas update instantly whenever prices change. 

A. Total Cost Formula (Column F) 

Click cell F2 and enter this formula: =D2*E2 

This calculates: Shares × Average Cost = Total Investment 

Copy this formula down to F3:F21. 

B. Market Value Formula (Column H) 

Click cell H2 and enter this formula: =D2*G2 

This calculates: Shares × Current Price = Current Market Value 

Copy down to H3:H21. 

C. Gain/Loss in Dollars (Column I) 

Click cell I2 and enter this formula: =H2-F2 

This calculates: Market Value – Total Cost = Profit/Loss 

Copy down to I3:I21. 

D. Gain/Loss Percentage (Column J) 

Click cell J2 and enter this formula: =IF(F2=0,0,(I2/F2)*100) 

Then format column J as Percentage  

This calculates: (Gain/Loss ÷ Total Cost) = Return Percentage 

Copy down to J3:J21. 

5. Build A Summary Dashboard 

Add a portfolio summary section starting at row 24 to track key metrics: 

A. Total Portfolio Value (In USD) 

Add this formula to calculate total current value: =SUM(H2:H21) 

B. Total Cost Basis (In USD) 

Add this formula to calculate total investment: =SUM(F2:F21) 

C. Total Gain/Loss ($) 

Add this formula to calculate total profit/loss: =B27-B28 

(Assuming B27 has portfolio value and B28 has cost basis) 

D. Total Return (%) 

Add this formula to calculate overall return percentage: =(B29/B28) 

E. Number of Holdings 

Add this formula to count active positions: =COUNTA(A2:A21) 

F. Best Performer 

Add this formula to identify top gainer: =INDEX(A2:A21,MATCH(MAX(J2:J21),J2:J21,0)) 

G. Worst Performer 

Add this formula to identify biggest loser: =INDEX(A2:A21,MATCH(MIN(J2:J21),J2:J21,0)) 

6. Creating Visual Alerts with Conditional Formatting 

Now set up conditional formatting to highlight significant movements and performance: 

Format Gain/Loss $ Column (I): 

1. Select column I (I2:I21) 
2. Go to Home : Conditional Formatting : New Rule 
3. Format cells > 0: Light green fill with dark green text 
4. Add another rule for < 0: Light red fill with dark red text 

Format Gain/Loss % Column (J): 

Repeat the same green/red formatting process for column J. 

Add Data Bars to Market Value (Column H): 

1. Select H2:H21 
2. Conditional Formatting : Data Bars : Blue Gradient Fill 

This creates visual bars showing the relative size of each position. 

Now your tracker will automatically highlight gains in green and losses in red, making it easy to spot performance at a glance. 

7. Set up Automated Email Alerts 

Since Excel Desktop doesn’t have built-in email automation, we’ll use Google App Script for automated email alerts. 

Steps for Setting Up Google Apps Script: 

1. Export to CSV: From Excel, save as CSV 
2. Upload to Google Sheets: Import the CSV file 
3. Add GOOGLEFINANCE: Replace column G with =GOOGLEFINANCE(A2,"price") 
4. Access Apps Script: In Google Sheets, go to Extensions : Apps Script 
5. Delete Default Code: Remove existing code 
6. Rename Project: Click “Untitled project” and rename to “Portfolio Alerts” 

Paste this complete script into the Code.gs file: 

function checkStockAlerts() { 

 const sheet = SpreadsheetApp.getActiveSheet(); 

 const data = sheet.getDataRange().getValues(); 

 const headers = data[0]; 

  // Find column indices 

 const symbolCol = headers.indexOf('Symbol'); 

 const companyCol = headers.indexOf('Company Name'); 

 const priceCol = headers.indexOf('Current Price'); 

 const dayChangeCol = headers.indexOf('Day Change %'); 

 const gainLossCol = headers.indexOf('Gain/Loss %'); 

 const sharesCol = headers.indexOf('Shares'); 

 const marketValueCol = headers.indexOf('Market Value'); 

  let alerts = []; 

  // Loop through each row (skip header) 

 for (let i = 1; i < data.length; i++) { 

   const symbol = data[i][symbolCol]; 

   const company = data[i][companyCol]; 

   const currentPrice = data[i][priceCol]; 

   const dayChange = data[i][dayChangeCol]; 

   const gainLoss = data[i][gainLossCol]; 

   const shares = data[i][sharesCol]; 

   const marketValue = data[i][marketValueCol]; 

   // Skip if no symbol 

   if (!symbol) continue; 

   // Alert if day change > 5% or < -5% 

   if (Math.abs(dayChange) >= 5) { 

  alerts.push({ 

    symbol: symbol, 

    company: company, 

    type: 'Daily Movement', 

    message: `${symbol} (${company}): ${dayChange.toFixed(2)}% day change`, 

    details: `Current Price: ${currentPrice.toFixed(2)} | Shares: ${shares} | Value: ${marketValue.toFixed(2)}` 

  }); 

   } 

   // Alert if gain/loss milestone reached 

   if (gainLoss >= 50) { 

  alerts.push({ 

    symbol: symbol, 

    company: company, 

    type: 'Profit Milestone', 

    message: `${symbol}: +${gainLoss.toFixed(2)}% gain reached!`, 

    details: `Current Price: ${currentPrice.toFixed(2)} | Position Value: ${marketValue.toFixed(2)}` 

  }); 

   } else if (gainLoss <= -20) { 

  alerts.push({ 

    symbol: symbol, 

    company: company, 

    type: 'Loss Warning', 

    message: `${symbol}: ${gainLoss.toFixed(2)}% loss alert`, 

    details: `Current Price: ${currentPrice.toFixed(2)} | Position Value: ${marketValue.toFixed(2)}` 

  }); 

   } 

 } 

  // Send email if alerts exist 

 if (alerts.length > 0) { 

   sendAlertEmail(alerts); 

   Logger.log('Alert email sent with ' + alerts.length + ' alert(s)'); 

 } else { 

   Logger.log('No alerts to send at this time'); 

 } 

} 

function sendAlertEmail(alerts) { 

 // CHANGE THIS TO YOUR EMAIL ADDRESS 

 const emailAddress="[email protected]"; 

  // Build email subject 

 const subject="🚨 Stock Alert: " + alerts.length + ' Position(s) Require Attention'; 

  // Build email body 

 let body = 'Portfolio Alert Summary\n'; 

 body += '═══════════════════════════\n\n'; 

  // Group alerts by type 

 const dailyMovement = alerts.filter(a => a.type === 'Daily Movement'); 

 const profitMilestones = alerts.filter(a => a.type === 'Profit Milestone'); 

 const lossWarnings = alerts.filter(a => a.type === 'Loss Warning'); 

  // Daily movement alerts 

 if (dailyMovement.length > 0) { 

   body += '📊 SIGNIFICANT DAILY MOVEMENTS:\n\n'; 

   dailyMovement.forEach(alert => { 

  body += alert.message + '\n'; 

  body += alert.details + '\n\n'; 

   }); 

 } 

  // Profit milestone alerts 

 if (profitMilestones.length > 0) { 

   body += '💰 PROFIT MILESTONES:\n\n'; 

   profitMilestones.forEach(alert => { 

  body += alert.message + '\n'; 

  body += alert.details + '\n\n'; 

   }); 

 } 

  // Loss warning alerts 

 if (lossWarnings.length > 0) { 

   body += '⚠️ LOSS WARNINGS:\n\n'; 

   lossWarnings.forEach(alert => { 

  body += alert.message + '\n'; 

  body += alert.details + '\n\n'; 

   }); 

 } 

  // Add footer 

 body += '═══════════════════════════\n'; 

 body += 'Alert generated: ' + new Date().toLocaleString() + '\n'; 

 body += 'Check your portfolio tracker for full details.\n'; 

  // Send the email 

 try { 

   GmailApp.sendEmail(emailAddress, subject, body); 

 } catch (error) { 

   Logger.log('Error sending email: ' + error); 

 } 

} 

function testEmailAlert() { 

 // Test function to verify email works 

 const testAlerts = [ 

   { 

  symbol: 'TEST', 

  company: 'Test Company', 

  type: 'Daily Movement', 

  message: 'TEST: 5.5% day change (This is a test)', 

  details: 'Current Price: $100.00 | Shares: 10 | Value: $1,000.00' 

   } 

 ]; 

  sendAlertEmail(testAlerts); 

 Logger.log('Test email sent');
