You're wasting the only edge you actually have

You open the app again. You check your positions. One tech stock is up 14%. That Chinese company you bought on a hunch is down 7%. You scroll through financial news, watch a guy on YouTube explain why some mega-cap is going to double. An hour passes. You don't buy anything. You don't sell anything. You close the app.

Tomorrow you'll do it again.

This is the most expensive habit. Not because you're losing money - your portfolio is probably fine. It's expensive because every hour you spend managing a small starter portfolio is an hour you could have spent building something, learning something, or earning something. And at a few thousand euros, none of the decisions you're agonizing over actually matter yet.

Starter portfolios

You have a couple hundred euros in some semiconductor stock. It goes up 50%? Congratulations, you made enough for a decent dinner. It drops 40%? Also a dinner, in the other direction. Meanwhile, your monthly savings plan will add a few thousand to your portfolio this year regardless of what any individual stock does. At this stage, how much you put in matters roughly ten times more than what you put it in.

This changes later. When your portfolio hits €100,000, a 5% position represents quite some money and a 50% gain on it actually moves the needle. That's when individual picks start to earn their place. But treating a small starter portfolio like a hedge fund is like optimizing the aerodynamics of a bicycle. Technically it does something. Practically it's not where the leverage is.

The attention tax

Stock picking isn't free even when you don't trade. Every position you hold takes up a small piece of your mental bandwidth. You track the news. You notice when it's red. You feel a little dopamine hit when it's green. You read earnings reports you don't fully understand and form opinions based on what other people who also don't fully understand them are saying.

With eight or nine positions across individual stocks, regional ETFs, and broad index funds, you've built yourself a part-time job that pays almost nothing per hour. Most of this activity feels like work but is actually entertainment. It feels productive because you're learning about markets and companies and macroeconomics. And you are learning - but the ratio of learning to doing is way off. You're studying the menu instead of eating.

94% of professionals fail

Over any 20-year period, 94% of professional fund managers - people who do this full-time with analyst teams and Bloomberg terminals and decades of experience - fail to beat a simple index fund. That's the most replicated finding in finance. If they can't do it, you're not going to do it on your phone between meetings.

The ones who do beat the market have genuine information advantages - deep industry expertise, proprietary data, relationships that surface insight before the market prices it in. Scrolling Reddit and watching YouTube finance channels is not that. It's consuming the same information as millions of other retail investors, which means it's already baked into the price. By the time you read about why some chipmaker is undervalued, the market incorporated that thesis last week.

Your edge

Your advantage at young age is trifold:

Time. €200 a month at 7% for 40 years becomes nearly half a million. Start at 34 instead of 24 and you'd need to double your contributions just to catch up. For 125 years, across 35 countries, global equities have returned about 5% above inflation per year - through world wars, depressions, pandemics, and dozens of crashes. Your job is to be on the train.

Earning power. The skills you build, the projects you ship, the relationships you form in the next five years will increase your income by multiples. An extra couple hundred per month in contributions beats an extra 2% in returns every single time at a small portfolio size.

Behavior. The average equity investor earned 16.5% in 2024 while the S&P 500 returned 25%. That 8.5-point gap isn't because the funds are bad - it's because people buy after things go up and sell after things go down. They panic. They chase. They tinker. The investor who automates a monthly contribution and checks it once a quarter will beat most active investors simply by not making mistakes. Fidelity reportedly found their best-performing accounts belonged to people who had either forgotten about them or were dead.

Nobody knows

Europe has its problems. America has its problems. China has its problems. Every few months someone has a convincing take on why you should overweight this region or avoid that one. Wars, elections, tariffs, recessions - there's always something. And the people who sound most confident are either selling something or got lucky and built a story around it afterwards.

Warren Buffett bet $1 million that a plain index fund would beat hand-picked hedge funds over ten years. The index returned 125%. The hedge funds averaged 36%. His will tells his wife's trustee to put 90% in an index fund. The man who made $100 billion picking stocks tells everyone else not to bother.

A world index fund is you saying "I don't know which country or company wins, but I know the world economy keeps growing over decades." That's not lazy. That's the most honest position available.

What to do

Sell the individual positions. Not because they're bad companies - most of them are probably excellent businesses. Sell them because at this portfolio size, the complexity and attention cost aren't worth it. A global index fund gives you 3,500+ companies across 50 countries. It rebalances automatically. It costs 0.19% per year. It requires nothing from you.

Redirect the attention. Put those hours into the thing that actually moves the needle at your stage of life - building skills, shipping projects, increasing your income. Every €100/month increase in contributions, sustained over 15 years at 7%, adds roughly €31,000 to your outcome. No stock pick will match that.

The most sophisticated thing a young investor can do is the simplest thing available: own everything, contribute consistently, and spend your energy where it compounds - on yourself.
