Introduction to investing in index funds and ETFs: A practical guide for investors in Europe

“I want to grow my savings. But, I don’t know how to invest.”

It is awful to see your hard-earned savings erode due to low – actually, almost non-existing – interest rates. You can’t help but feel like your savings are going nowhere while stuck in a bank account.

You hear you can grow your savings if you invest them. But you don’t know how to do it prudently

Saving is easy. You spend less than you earn. You know how to do that. But investing?! Investing sounds complicated, time consuming and speculative. 

“Worse, investing is risky! Will I make a big mistake and lose my money? I am not an expert.”

Your family and friends also know little about investing. You didn’t study Finance in school. You don’t know who and what to ask. Investing is a foreign concept. You don’t even know where to begin.

You have read a few things about investing but you get confused with all the acronyms and terms: TER, market capitalization, broad index…

What if you knew how to invest your savings the right way?

The Internet has a ton of suspicious “get rich quick investing” schemes. And you don’t want to get involved with them. However, there is a time-tested simple investment strategy – index/passive investing – which has produced great returns for investors like you and me.

You’ve stumbled into a couple of amazing resources but they were all written by people that live in the United States (US). Can I invest like them? What is a 401(k) anyway? How can European residents buy VTI/VTASX? 

What if you specifically knew how European residents can invest in index funds?

Taxes, regulations, brokers and available funds make investing while living in Europe different than investing while living in the US. The principles of passive investing are the same regardless of location. But the practical details differ.

My book “Introduction to investing in index funds and ETFs” covers what you need to know and do so you can start investing. It covers both the theory and practice of investing in index funds for residents in Europe.

A list of “best ETFs for Europeans” can only take you so far. It tells you “what” but it does not explain you “why”. Investing with so little knowledge feels like you are flying blind. You are doing something but you don’t know if it will take you where you need to go. This book is different.

Give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime.

This book is about learning how to fish. This book is about becoming confident on your ability to make sound investment decisions. 

You need not spend months researching how to invest in index funds. You can quickly learn how to invest your savings without having to take a PhD on Economics. You can learn passive investing in a couple of hours with this book.

What is inside?

The book explains the essential concepts and steps for starting with passive investing while living in Europe. Besides the book there are videos that cover supplemental topics relevant for investors: taxes, brokers and online tools.

The book

It is an ebook with around 100 pages. It has 6 chapters:

  • Chapter 1 – Introduction to Investing: Covers the fundamentals of investing. What is investing and why people bother doing it? What are the different investments (e.g. equities, bonds) that exist and how do they work? What is the risk/return trade-off? What is the importance of diversification?
  • Chapter 2 – Introduction to Passive Investing: Covers the fundamentals of passive investing. How is passive investing different from other types of investing? Why is passive investment great for investors like you and me? What is an investment fund? How is the passive investing landscape in Europe?
  • Chapter 3 – Introduction to the Simple Portfolio: Covers the details of my preferred portfolio. How does that portfolio look like? Why is it a popular portfolio among European investors? A deep understanding of this portfolio makes it easier to find the most suitable investment funds.
  • Chapter 4 – Understanding Index Funds: Explains the important characteristics of equity and bond index funds. Before you can choose funds for your portfolio, you need to evaluate them and assess if they fit your investment plan.
  • Chapter 5 – Preferred ETFs: Covers my preferred ETFs for implementing the Simple Portfolio. I explain the process I follow to find suitable ETFs. I’ll help you understand why I prefer these specific ETFs instead of others.
  • Chapter 6 – Asset Allocation: Explains the importance of investing in both equities and fixed income. I’ll explain how you can find an equity/fixed income split that works for you and how to rebalance your portfolio.

Along with the book you will get a spreadsheet with useful information related to the book: detailed ETF analysis, source data for graphs/tables, historical data.

Video: How to select ETFs in practice for the Simple Portfolio

The book explains my process for selecting ETFs, which I call “Exclude + Prioritize”. This process chooses a few suitable ETFs from a universe of hundreds of ETFs. The book explains the process in a written format.

This video is a live walkthrough where I run the same “Exclude + Prioritize” process. In it you will learn how to use multiple online tools to select the best ETFs for you in practice.

Video: Walkthrough of useful online resources

The Internet is the best friend of any index investor.

This video covers the most useful online resources for European index investors. You will learn about tools that help you find information about ETFs, that help you find information about financial markets and that help you learn more about investing.

Video: Guide to brokers for index investors

You need a broker to invest in ETFs. In this video you will learn how brokers work. You will also learn how to use a broker and how to choose one. You will learn about the common aspects among brokers.

Video: Guide to taxes for index investors

At first sight taxes look complicated but they don’t have to. They are simple when you understand the core principles.

In this video you will learn about the fundamentals of taxes so you easily find about the specific details for your specific case. This video explains aspects of taxes that investors should be aware of.

What are people saying?

“I have read some materials in the past regarding investing in ETFs but usually all was ending in confusion. After reading your blog I actually started investing.” – Martin D. (Bulgaria)

“You always break everything down with many examples and in plain language. I really like your tone and the way you explain things. Also, the fact that your guides are European-centered makes it very relevant for people like me to read what you have to say and act on it.” – Pasi M. (Finland)

“Index Fund Investor blog is THE place to go for the practical aspect of investing as a European. I’ve been following Mário’s work for more than 6 months. There is plenty of investment blogs available online, however, I haven’t found anything that practical. I strongly believe that investing requires a good foundation of knowledge. One needs to understand the basics to be able to make educated decisions. Mário helps you to bridge the gap between the abstract concept of investing with the practical need of implementing your plans. You get introduced to real-life tools and financial instruments. The blog lowers the barrier of entry and I highly recommend it to any aspiring investor.“ – Maciej G. (Germany)
