First Investment: How to Really Start, Step by Step

It's Friday evening, you're lying on the couch scrolling through your phone. A friend sent you a screenshot showing how a stock he owns has grown significantly over the year. You open an investment app, register, deposit 5,000 Kč — and then you stare at a screen filled with thousands of tickers and charts that look like EKGs. Your finger hovers over the "Buy" button. And you know absolutely nothing. We've all been there.

Good news: you can start in a way that's not just random tapping. There is a sequence of steps that makes sense even on paper. Let's go through it — with concrete numbers, not just phrases.

First, the Math That Will Protect You

Before you send your first crown to the stock market, you need to know one thing: only invest money you won't need for a year or two. Why this particular timeframe?

The stock market grows over the long term, but it can be quite volatile in the short term. Historically, the main American index (S&P 500) has fluctuated from declines of around −37% (in 2008) to increases of over +30% in individual years. If you need to withdraw money for rent in such a year, you're selling exactly when you're at a loss. It's like selling a bike in winter when no one wants it.

Therefore, step zero: reserve. Keep about 3–6 months' worth of expenses in a savings account. Only what remains goes to the stock market.

A Small Example with Numbers

Let's say you have a net income of 25,000 Kč and monthly expenses of 18,000 Kč. The reserve should be roughly 54,000–108,000 Kč. Until you have it, investing can wait. Once it's filled, it makes sense to send perhaps 1,000–2,000 Kč monthly regularly. Not all your savings at once — regularly.

Why Regularly and Why Small

Here comes the magic called dollar-cost averaging. When you send the same amount each month, you automatically buy more shares when they're cheap and fewer when they're expensive. You don't have to guess "when is the right time" — because almost no one can guess that.

The data is quite unforgiving: most people (even professionals) who try to time the market — to hit the bottom and the peak — long-term underperform compared to those who simply bought regularly and boringly. Boredom is your friend here.

And why small? Because the first year is mainly training for your own psychology. You want to find out how you feel when your portfolio value drops by 8% in a week. It's better to find this out with 3,000 Kč than with 300,000 Kč.

One Broad Basket vs. Hunting Individual Stocks

A complete beginner usually has two paths:

• Broadly diversified fund (ETF) — with one purchase, you buy a tiny piece of hundreds or thousands of companies at once. It's like betting on the entire league instead of guessing which player will score.
• Individual stocks — you choose specific companies. More fun, but more demanding and riskier, because one company can have a bad year even if the market grows.

Why do many beginners start with a broad basket? Because of risk diversification. If you have one company in your portfolio and it drops by 50%, it hurts. If you have five hundred companies and one drops, you hardly notice. That's the whole point of diversification: you're not betting everything on one card.

Statistical Block — Why Diversification Works

Historically, the longer you hold a broadly diversified stock portfolio, the less likely you are to end up in the red. On a one-year horizon, losing years were quite common. On a 15+ year horizon, the vast majority of periods in a broad index were historically positive. Note — history is not a guarantee of the future, it's just a description of what happened. But it shows a clear pattern: time + diversification = a calmer sleep.

Step by Step: Practical Checklist

Here's a specific sequence you can check off today:

1. Write down your reserve. Monthly expenses × 3 to 6. This number must be set aside.
2. Determine the amount for investments. How much can you send monthly without worrying about it? Be honest — better 500 Kč regularly than 5,000 Kč once and then nothing.
3. Choose a broker/platform. Pay attention mainly to fees (for purchase, maintenance, currency conversion) and whether it's regulated. Small fees can save you surprisingly much over the years.
4. Decide on a style. Do you want a calm broad basket, or do you also want to pick individual companies? Feel free to combine — perhaps a "core" in a broad fund and a small playful part in individual stocks.
5. Set up automatic purchases, if possible. This removes you from the equation — and your emotions are often your biggest enemy.
6. Don't check it every day. Seriously. Frequent checking increases the chance you'll sell in panic. Once a month or quarter is enough.

Behavioral Trap Almost Everyone Falls Into

There is a phenomenon that economists have described quite precisely: we perceive the pain of loss about twice as strongly as the joy of an equally large gain. This means that when your portfolio drops by 1,000 Kč, you feel it as if someone took 2,000 from you. And that's exactly when beginners sell and run away.

How to deal with it? Write down a rule on paper beforehand: "The money I sent is for 10 years. Drops are normal. I sell only according to plan, not mood." It sounds like a cliché, but that paper will really help you in panic. It's like having a pre-agreed strategy before you go on a roller coaster.

How to Choose What to Actually Look At

Once you have the basics and you're tempted to pick individual companies, you'll encounter a problem: there are thousands of companies. How to compare them at all? You look at things like company size, profits, debt, how expensive the stock is relative to earnings, whether it pays a dividend. Going through it manually is like reading a phone book.

In QMA: this is exactly what a screener does for you — you set criteria (like "stable companies with low debt") and the tool filters a narrower list from thousands of titles for you to explore. You see a clear score for each title, so you don't have to decipher tables yourself. It's not a command on what to buy — it's a way to narrow down the heap to something you can realistically study. open in QMA

Most Common Mistakes of Complete Beginners

• Investing money they need in two months. Classic. Leads to selling at the worst time.
• Buying everything at once instead of regularly and then panicking at the first drop.
• Chasing tips from the internet — "this stock will fly." When someone pushes you to buy quickly, they usually profit, not you.
• Checking the portfolio five times a day. Recipe for a heart attack and rash decisions.
• Forgetting about fees. A seemingly small number that cuts a big chunk over the years.

What to Take Away

1. First reserve, then investment. Set aside 3–6 months' worth of expenses and only then send the rest to the market.
2. Start with a small, regular amount — the first year is mainly training your psychology, not chasing returns.
3. Diversify risk — a broad basket of companies protects you better than betting on a single card.
4. Narrow down your selection smartly — before you start going through thousands of companies manually, have them pre-filtered: open in QMA.

And most importantly — don't rush. Investing is not a lottery where the fastest buyer wins. The winner is usually the one who lasts the longest and doesn't make rash moves. Your first investment doesn't have to be brilliant. It just needs to be small enough, diversified enough, and boring enough for you to stick with it.
