What is a stock?
A stock is a share of ownership in a company. That’s the most important sentence in this guide — read it again: a stock is a share of ownership in a company.
Imagine a friend starts a pizza restaurant. The restaurant costs $100,000 to set up. You give him $10,000 and receive 10% of the restaurant in return. When the restaurant makes a profit, you get 10% of it. If the restaurant grows so successful that someone would pay $200,000 for it, your 10% is now worth $20,000.
That’s exactly what happens with stocks. Large companies like Apple, Microsoft, or Tesla are divided into millions of small ownership pieces called shares. When you buy one Apple share, you own a tiny piece of Apple. When Apple makes a profit, you get a portion — either as a dividend (a direct cash payment) or as an increase in the stock’s price.
Why people buy stocks
1. Building wealth. Historically, stocks have delivered the best long-term returns of any asset class. The S&P 500 has returned an average of approximately 10% per year over the past 50 years. Someone who invested $10,000 had around $174,000 after 30 years.
2. Protection against inflation. Money sitting in a savings account loses purchasing power every year due to inflation. Quality companies can raise their prices along with inflation, helping protect your wealth over time.
3. Passive income through dividends. Many stocks pay regular profit distributions. Coca-Cola has paid and increased its dividend every single year for over 60 years.
The risks — honest and unfiltered
Stocks are not a savings account. Prices can fluctuate — both up and down. Over the past 100 years there have been several major market crises where stock indices fell 40–50%. But these crises were always temporary.
The golden rule: Only invest money you won’t need for at least 5–10 years. Investors who stayed the course have historically always recovered and gone on to profit.
How much money do I need to buy stocks?
The short answer: far less than you think. With modern brokers like Trade Republic you can start investing from just $1 — through so-called fractional shares.
Our recommended starting amounts:
- Complete beginner, just testing: $50 to $100
- Regular savings plan: $25 to $50 per month
- First meaningful investment: $500 to $1,000
Key insight: What matters most is not the amount, but starting early. Thanks to compound interest, time is your greatest advantage. $100 invested today could be worth more in 30 years than $1,000 invested 10 years from now.

Open a brokerage account (10 minutes)
A brokerage account is like a bank account — except it holds stocks instead of cash. Opening one is completely digital today and takes about 10 minutes.
What you need:
- Passport or national ID card
- Smartphone with camera (for video verification)
- Bank account for transfers
- Tax identification number
The process: Download the app → Enter email & phone → Personal details → Tax ID → Video verification → Done.
Fund your account
Before you can buy, money needs to be in your brokerage account. There are two ways:
- Bank transfer: Takes 1–2 business days, transfer from your bank account
- Instant deposit: Via Apple Pay or Google Pay, available immediately
Beginner tip: Start with $100 to test the process — learn the flow without significant risk.
Choose your first stock
There are over 50,000 tradeable stocks worldwide. How does a beginner choose? Three proven approaches:
Approach 1: A company you know
Peter Lynch, one of the most successful fund managers of all time, said: “Buy what you know.” Use Apple products daily? Drink Coca-Cola? Understanding the business model is a great starting point.
Approach 2: A dividend aristocrat
Companies like Coca-Cola, Procter & Gamble, or Johnson & Johnson have paid and increased dividends for 25+ consecutive years — demonstrating stability and a robust business model.
Approach 3: An ETF instead of individual stocks
With a MSCI World ETF you buy shares in approximately 1,500 companies simultaneously — maximum diversification with minimal effort. Perfect for beginners.
Do a quick analysis
Before buying, quickly check these 3 things:
- What does the company do? — Do you understand the business model?
- Price performance over the last 5 years: — Has it grown steadily or is it volatile?
- Does it pay dividends? — And are they growing over time?

Place your buy order
In Trade Republic, buying takes just a few seconds:
- Search for the stock (e.g., “Apple” or ISIN “US0378331005”)
- Tap “Buy”
- Enter the amount (e.g., $100) or number of shares
- Choose order type: for beginners, always use a Market Order
- Review the summary and confirm with your PIN
Market Order vs. Limit Order: A market order buys immediately at the current market price — simple and fast. A limit order only executes when the stock reaches a specific price. As a beginner: use market orders.
What happens after you buy
Congratulations — you’re now a shareholder! What’s next?
- Short term: Don’t check prices too often. Price swings are normal — don’t let them rattle you.
- Medium term: Monitor your investment, read quarterly reports, build experience.
- Long term: Diversify your portfolio to 10–20 stocks or combine with ETFs.
- Taxes: Trade Republic automatically withholds capital gains tax — 25% (DE) or 27.5% (AT). You don’t need to calculate anything yourself.
The Most Common Beginner Mistakes
These mistakes cost beginners the most money and stress. Know them — and avoid them from day one.
- Selling in panic when prices fall. A paper loss is not a real loss. Only when you sell does it become real. Quality stocks have historically always recovered.
- Chasing whatever is trending right now. Meme stocks, hot tips, social media hypes — those who join last tend to lose. Your own research beats herd mentality.
- Putting too much into a single stock. Spread your capital across at least 5–10 positions. Never more than 10–15% in any single stock.
- Investing money you’ll need soon. Stocks can fall short term. Only use capital you can leave invested for 5–10 years.
- Investing without a plan. Define upfront: Why am I buying this stock? When will I sell? At what loss do I re-evaluate my thesis?
