If you are preparing for the Wharton Global High School Investment Competition (WGHS), you have probably heard of the Wharton Investment Simulator (WInS) — the proprietary online trading platform that serves as the backbone of the entire competition. But what exactly is WInS? How does it work? And more importantly, how can you and your team use it to build a winning investment strategy?
In this comprehensive technical guide, we take you inside the WInS platform. We will walk you through every major feature, explain how the simulation works, and give you practical tips for maximizing your effectiveness during the 8-week trading period. Whether you are a first-time competitor or a returning participant looking to sharpen your skills, this guide will help you navigate WInS with confidence.
What Is the WInS Platform?
The Wharton Investment Simulator is a web-based portfolio management tool developed by Wharton Global Youth Programs specifically for the WGHS competition. It is not a generic stock market game — it is a sophisticated simulation designed to mirror the experience of professional investment management.
Here is what makes WInS unique:
Real Market Data: WInS uses real-world stock prices, ETF values, and mutual fund performance data. When you buy or sell a security on WInS, you are transacting at prices that reflect actual market conditions.
Proprietary Universe of Securities: WInS does not include every stock in the market. Instead, it offers a curated selection of stocks, ETFs, and mutual funds across various sectors and asset classes. This ensures that the platform remains manageable for high school students while still providing enough diversity for sophisticated portfolio construction.
Client-Focused Design: Unlike many trading simulators that reward pure speculation, WInS is designed to support the client-focused approach that WGHS is known for. The platform encourages thoughtful, research-driven decision-making rather than impulsive trading.
Integrated Reporting Tools: WInS provides built-in tools for tracking your portfolio performance, analyzing holdings, and generating reports — all of which will be invaluable when you write your investment strategy report.
Getting Started: Your First Login
When the trading period opens in early October, your Faculty Advisor will provide your team with login credentials for the WInS platform. Here is what to expect during your first login:
Step 1: Access the Dashboard
After logging in, you will be taken to your team's main dashboard. This is your command center — the place where you can view your portfolio, execute trades, and access key information. Take some time to explore the dashboard and familiarize yourself with its layout.
Step 2: Review Your Client Profile
Your dashboard will display your team's fictional client profile. This includes details about the client's financial situation, goals, risk tolerance, and time horizon. Read this carefully — every decision you make on WInS should be guided by this profile.
Step 3: Explore the Securities Universe
WInS provides a searchable database of all available securities — stocks, ETFs, and mutual funds. You can filter by sector, asset class, market capitalization, and other criteria. Spend time exploring this universe before the trading period begins so you know what options are available to you.
Step 4: Understand Your Starting Cash
Your team will begin with a virtual $100,000 in cash. This is your total capital, and you will need to decide how to allocate it across different securities. You do not have to invest all of it immediately — holding some cash is a valid strategy, especially if your client's profile calls for a conservative approach.
Executing Trades: How to Buy and Sell
The trading interface is where you will spend most of your time during the competition. Here is how it works:
Placing a Buy Order
Search for a Security: Use the search bar to find the stock, ETF, or mutual fund you want to buy. You can search by ticker symbol or company name.
Review the Details: Click on the security to view its current price, historical performance, and key metrics (P/E ratio, dividend yield, etc.).
Enter the Quantity: Specify how many shares (or what dollar amount) you want to purchase. WInS will calculate the total cost and show you how much cash you will have remaining after the trade.
Confirm the Trade: Review the details and click "Buy" to execute the trade. The shares will be added to your portfolio immediately.
Placing a Sell Order
Navigate to Your Holdings: Go to the "Portfolio" or "Holdings" section of your dashboard to see what securities you currently own.
Select a Security to Sell: Click on the security you want to sell and specify how many shares you want to liquidate.
Review the Proceeds: WInS will show you the current market value of the shares you are selling and how much cash you will receive.
Confirm the Sale: Click "Sell" to execute the trade. The shares will be removed from your portfolio, and the proceeds will be added to your cash balance.
Important Notes About Trading
Trades Execute at Current Market Prices: WInS uses real-time (or near-real-time) market data, so your trades will execute at prices that reflect actual market conditions.
No Short Selling or Margin Trading: WInS does not allow short selling or trading on margin. You can only buy securities with the cash you have available.
Trading Hours: Trades can typically be placed at any time during the trading period, but they will execute based on market hours. Check the platform for specific timing details.
Monitoring Your Portfolio
One of the most powerful features of WInS is its portfolio monitoring tools. These allow you to track your performance, analyze your holdings, and make informed decisions throughout the competition.
Portfolio Overview
Your dashboard provides a real-time snapshot of your portfolio, including:
Total Portfolio Value: The current market value of all your holdings plus your cash balance.
Cash Balance: How much uninvested cash you have remaining.
Asset Allocation: A breakdown of how your portfolio is distributed across asset classes (stocks, ETFs, mutual funds, cash).
Sector Exposure: How your portfolio is distributed across different sectors (technology, healthcare, financials, etc.).
Individual Holdings
For each security you own, WInS provides detailed information, including:
Number of shares owned
Average purchase price
Current market price
Total market value
Unrealized gain or loss
Percentage of total portfolio
Use this information to monitor how each holding is performing and whether it still aligns with your strategy.
Performance Tracking
WInS allows you to track your portfolio's performance over time. You can view charts showing how your portfolio value has changed since the start of the competition, compare your returns to benchmarks, and analyze your trading history.
This data will be invaluable when you write your investment strategy report. Judges want to see that you understand how your portfolio performed and why — not just whether you made money, but how your decisions aligned with your client's needs.
Advanced Features: Making the Most of WInS
Beyond the basics of buying and selling, WInS offers several advanced features that can help you build a more sophisticated investment strategy.
Rebalancing Tools
If market movements cause your portfolio to drift significantly from your target allocation, WInS provides tools to help you rebalance. You can identify which holdings have grown too large or too small relative to your target and make adjustments accordingly.
Rebalancing is an important part of professional portfolio management. It ensures that your portfolio remains aligned with your client's risk profile and investment goals, even as market conditions change.
Dividend Tracking
If your portfolio includes dividend-paying stocks or funds, WInS will track the dividends you receive and add them to your cash balance. This is important for clients who rely on dividend income — make sure you understand how dividends contribute to your portfolio's overall performance.
Trading History and Logs
WInS maintains a detailed record of every trade you execute, including the date, security, quantity, price, and rationale (if you choose to document it). Use this feature to keep a trading log throughout the competition — it will save you hours of work when you sit down to write your report.
Pro tip: After every trade, write a brief note explaining why you made that decision. This habit will force you to think critically about each trade and provide you with ready-made content for your investment strategy report.
Scenario Analysis
Some versions of WInS include scenario analysis tools that allow you to model how your portfolio might perform under different market conditions. For example, you can simulate how your portfolio would be affected by a 10% market downturn, a rise in interest rates, or a sector-specific shock.
These tools are invaluable for stress-testing your strategy and identifying potential vulnerabilities. If your portfolio is overly exposed to a particular risk, scenario analysis will help you see that before it becomes a problem.
Best Practices for Using WInS
Now that you understand how WInS works, here are some best practices to help you and your team use the platform effectively:
1. Familiarize Yourselves Before the Trading Period
Do not wait until the trading period opens to explore WInS. Wharton typically provides access to tutorial materials and practice environments before the competition begins. Use these resources to familiarize yourself with the platform so you can hit the ground running when the trading period starts.
2. Assign a Platform Lead
While every team member should understand how to use WInS, it is helpful to designate one person as the "platform lead" — the person who is most comfortable navigating the interface, executing trades, and troubleshooting technical issues. This person can serve as the team's go-to resource for platform-related questions.
3. Document Every Trade
As mentioned earlier, keep a detailed trading log. For every buy or sell, write down the date, security, quantity, and rationale. This habit will pay dividends when you write your report.
4. Review Your Portfolio Regularly
Do not just set your portfolio and forget it. Review your holdings at least once a week to ensure they still align with your strategy and your client's needs. If market conditions have changed significantly, consider whether adjustments are necessary.
5. Avoid Overtrading
WInS makes it easy to execute trades, but that does not mean you should trade constantly. Every trade should be deliberate and well-considered. If you cannot explain why you are making a trade in one or two sentences, you probably should not be making it.
6. Use the Data
WInS provides a wealth of data about your portfolio — use it. Analyze your asset allocation, sector exposure, and performance metrics. This data will inform your decisions during the trading period and provide the foundation for your investment strategy report.
7. Communicate as a Team
Make sure every team member knows what trades are being executed and why. Poor communication can lead to conflicting trades, duplicated work, or missed opportunities. Hold regular team meetings to discuss strategy, review performance, and coordinate next steps.
Troubleshooting Common Issues
Like any web-based platform, WInS may occasionally experience technical issues. Here are some common problems and how to address them:
Login Issues: If you cannot log in, double-check your credentials and make sure you are using the correct URL. If the problem persists, contact your Faculty Advisor, who can reach out to Wharton's technical support team.
Slow Performance: During peak trading hours, WInS may experience slower-than-usual performance. Be patient and avoid refreshing the page repeatedly, as this can exacerbate the problem.
Trade Execution Delays: If a trade does not execute immediately, do not panic. Check your portfolio and trading history to confirm whether the trade was processed. If there is a significant delay, contact your Faculty Advisor for assistance.
Data Discrepancies: If you notice a discrepancy in your portfolio data (e.g., incorrect share count or cash balance), document the issue and notify your Faculty Advisor immediately. Wharton's technical team can investigate and resolve the problem.
Final Thoughts: WInS Is a Tool, Not a Strategy
The Wharton Investment Simulator is a powerful platform, but it is just that — a tool. It can help you execute trades, monitor your portfolio, and analyze your performance, but it cannot replace critical thinking, strategic planning, or teamwork.
The teams that succeed in WGHS are not the ones with the most sophisticated understanding of the platform — they are the ones who use the platform effectively to implement a well-researched, client-focused investment strategy. Master WInS, yes — but never forget that the real key to success lies in your ability to think critically, work collaboratively, and make decisions that serve your client's needs.
