To practise investing with friends using an index scored paper portfolio, you build a shared leaderboard of mock trades and measure your returns against a standard benchmark like the MSCI World index, all without risking any real money. By learning the mechanics of the market in a safe environment, you can test your ideas and understand price volatility before you deploy your actual savings.
For many retail investors in Europe, the financial markets seem intimidating, opaque, and fraught with risk. The fear of making a costly mistake keeps a lot of people in cash, which slowly loses its purchasing power over time. A practice circle removes this anxiety entirely. When you team up with friends to track mock investments, you create a social, educational sandbox. You can celebrate the wins, analyse the losses, and hold each other accountable, all while keeping your actual bank accounts perfectly intact.
In this guide, we will explore exactly how to set up an investing club for practice, why comparing your results to a broad market index is crucial, and how to use this method to prepare for your eventual journey toward financial independence.

Why a paper portfolio is the safest way to learn
A paper portfolio is simply a simulated investment account where you buy and sell real securities using fake money. The prices update just as they do in the real world, but your actual net worth remains unaffected. This tool is invaluable for beginners because it separates the mechanical act of investing from the emotional weight of risking your own capital.
A paper portfolio acts as a sandbox, allowing you to make rookie mistakes and experience market volatility without suffering any actual financial loss. When you buy your first stock or exchange-traded fund, watching the value drop by a few percentage points on the very first day can trigger panic. By experiencing these normal market fluctuations with mock capital, you train your brain to tolerate the red days. You learn how bid and ask spreads work, how market orders differ from limit orders, and how external news events affect asset prices.
Practising with a group of friends adds a layer of shared learning. Instead of researching in isolation, you can pool your knowledge. If one friend investigates renewable energy companies and another looks into European banking stocks, you both benefit from the shared research. Moreover, a paper portfolio lets you ignore complex local legislation temporarily. For instance, in a real account, Romanian investors face a 10% flat capital gains tax on net profits, a rule enforced by the ANAF (the national tax authority). While paper trading, you do not have to worry about filing tax returns or calculating withholding tax, allowing you to focus entirely on the fundamentals of asset allocation.

The importance of scoring against a benchmark index
When you pick individual stocks, it is easy to feel like a genius in a rising market. If you buy a technology stock and it goes up by a certain amount, you might assume you made a brilliant choice. However, if the overall stock market went up by a larger amount during the same period, your brilliant choice actually lost you relative value. This is why you must score your paper portfolio against an index.
A stock pick is only successful if its return exceeds the simple, low-effort alternative of holding a broad market index fund. An index scored paper portfolio tracks your mock trades and compares them side-by-side with a benchmark, such as the S&P 500 or the MSCI All Country World Index. The benchmark represents the default path: what you would have earned if you had just bought a cheap, accumulating UCITS ETF and done absolutely nothing. If your active picks do not beat this benchmark, you are taking on additional risk and doing extra work for a worse outcome.
The concept of benchmarking is not just a useful mental model; it is a regulatory standard. The ESMA (European Securities and Markets Authority) requires professional fund managers to compare their performance against an appropriate benchmark in their key information documents. You should hold your own practice circle to the same professional standard. If a professional fund manager has to justify their existence against an index, your friend group should do the same.
Scoring against an index is profoundly humbling. It quickly teaches most retail investors that consistently beating the global market is incredibly difficult. This realisation is usually the turning point that pushes beginners toward a sensible, long-term strategy of buying and holding broadly diversified funds.
Setting the rules for your private practice circle
To make the experience useful and fair, your friend group needs a structured set of rules before anyone makes their first mock trade. Without rules, a practice circle can quickly devolve into a chaotic guessing game where people casually claim they would have bought a winning stock yesterday. Structure creates accountability.
Clear rules transform a casual conversation into a rigorous educational tool that prepares you for real market mechanics. When establishing your practice circle, sit down with your friends and agree on a framework that mirrors reality as closely as possible. You are not trying to create a casino; you are trying to build a resilient investment philosophy.
Here is a list of essential rules to implement for your practice circle:
- Define a starting capital limit: A standard starting mock balance of 10,000 EUR gives everyone enough virtual capital to build a diversified portfolio while remaining a realistic figure for retail investors.
- Choose a single benchmark index: Agree on a specific benchmark, like a global developed markets index, so everyone is measured against the exact same standard of success.
- Prohibit retroactive trading: All trades must be logged and shared with the group at the exact time they are placed, using the live market price, to prevent people from claiming they bought the dip after the fact.
- Set a minimum holding period: Encourage long-term thinking by requiring that any paper pick be held for at least one full month, discouraging manic day-trading behaviour.
By enforcing these rules, you simulate the constraints of an actual brokerage account. If someone wants to learn more about the broader ecosystem, they can check out the about section of the Denwyn project, which details our philosophy on transparent, educational investing.
Writing down your investment thesis
The single most powerful habit you can develop in a practice circle is writing down the reason for every trade you make. In the investing world, this is called an investment thesis. It is a short, logical argument explaining why you believe a specific asset is mispriced or poised for growth.
Documenting your investment thesis prevents hindsight bias from clouding your judgement when a trade inevitably goes wrong. Human memory is highly malleable. If you buy a retail stock because you think they will have strong holiday sales, and the stock instead crashes due to a supply chain issue, you might convince yourself later that you knew the supply chain was a risk all along. If your thesis is written down and shared with your friends, you cannot lie to yourself. You are forced to confront the gap between your expectations and reality.
When writing your thesis for the group, it does not need to be a dense financial dissertation. It just needs to be specific enough to be tested. A good thesis should contain a few mandatory components.
Every time you log a paper pick, your written thesis must include these elements:
- The core catalyst: A specific event, trend, or earnings metric that you believe will drive the price upward in the near future.
- The fundamental valuation: A brief explanation of why the company is currently undervalued compared to its peers or its own historical average.
- The exit condition: The exact scenario or target price at which you will admit you were wrong and close the mock position, capping your theoretical losses.
- The timeline: The duration you expect it will take for your thesis to play out and be recognised by the broader market.
Sharing these written notes in your private circle sparks brilliant conversations. Your friends can poke holes in your logic before you hit the mock buy button, providing a peer-review process that professional analysts rely on daily.
Transitioning from practice to real financial independence
Eventually, the goal of a practice circle is to give you the confidence to deploy your actual savings. Once you have seen how markets operate, survived a few mock drawdowns, and realised that beating the index is harder than it looks, you are ready to start investing for financial independence, often known as the FIRE movement.
When you transition to real money, the focus usually shifts from picking individual stocks to building a reliable, automated portfolio of broad market funds. You move from trying to win a game against your friends to securing your financial future. To do this, you rely on the mathematics of compound interest and safe withdrawal rates, which provide a predictable roadmap to retirement.
For the sake of planning your actual retirement, a solid default assumption for broad market growth is a nominal expected return of 7.0% a year. When factoring in inflation at 2.5% a year, your real return settles around 4.4% a year, which represents your true increase in purchasing power. To achieve financial independence, a safe withdrawal rate of 4% gives you a clear target based on the classic rule of 25. This means you need to accumulate twenty-five times your annual expenses to safely retire.

Real investing is less about the thrill of a brilliant stock pick and more about the quiet, consistent discipline of putting money away every month. A paper portfolio gets the gambling urge out of your system, allowing you to approach your real wealth with the seriousness it deserves. You can compare different strategies over time, but the ultimate winner is always patience.
