by Burton G. Malkiel is undoubtedly a classic of financial literature. Since its first publication in 1973, this book has earned a permanent place in the library of every investor. Nevertheless, in the end I was not completely convinced.
The book generally aims to make the principles and strategies of investing understandable to laypeople. And it does so without going into unnecessary technical details and possibly overloading the subject. The author uses a broad scientific foundation to suggest that the markets are by and large efficient. Even if this fact may be deeply offensive to some stock market players.
This means that it is not only difficult to beat the market at all. It is almost impossible to do so in a systematic and replicable way. Especially considering the time and financial costs involved. In view of the scientific findings of recent decades, Burton G. Malkiel therefore focuses instead on portfolio management and a passive investment approach.
A key aspect of the book is already mentioned in the title: the idea of the "random walk". In wide circles of the financial sector, this term is still used today as a derogatory remark. The author shows, however, that this understanding - although unpalatable to many - is quite obvious. He describes: The price movements of Stocks are essentially random in nature and therefore unpredictable. He illustrates this idea with numerous examples from the history of the financial markets. He then uses these examples to explain why active investing is not necessarily the most sensible idea.
The book is divided into four main sections, each dealing with a different aspect of investing:
In the first section, "Shares and what they are worth", Burton G. Malkiel takes us through the basics of investing. He also explains concepts such as the efficient market hypothesis and the random walk. It's a chapter that certainly won't hurt some readers - even the supposedly more experienced ones from the financial sector. He also addresses some common criticisms of these concepts, which are all too often based on a misunderstanding of them.
The second section is entitled "How the professionals turn the big wheel". It deals with various investment strategies, from technical and fundamental analysis to modern portfolio theory and behavioral economics. The author names a whole series of critical facts and studies and clears up various misconceptions. Private investors in particular should have internalized one thing: Others only boil with water and professional investors usually do no better than the general public.
"To make one thing very clear: this is not a book for speculators, nor is it a book for day traders who want to bet on hourly fluctuations in share prices without commission. The subtitle for this book could have been: How to get rich slowly but surely."

"The new investment technology" is the title of the third section. In this section, Burton G. Malkiel explains the importance of diversification, risk-taking and new methods of portfolio construction. By the end of this chapter at the latest, you should have understood how relevant portfolio construction is in relation to the selection of individual securities. It also dispels some of the myths surrounding diversification that many well-known authors, bloggers and journalists still subscribe to.
"Randomness is rather an indication that a market is functioning well and efficiently and is not behaving irrationally. If prices reflect all known information, even uninformed investors who buy a broadly diversified portfolio at market prices will achieve just as high a return as experts. Of course, the stock market may not fully price in a particular newsworthy event. Daily price changes can also sometimes deviate from the random principle. Therefore, with regard to the stock market, 'relative' rather than absolute efficiency can probably be assumed."

From this point onwards, however, there is, in my opinion, an unpleasant break in the book. Although, in retrospect, I already found the first signs of this in the first three sections, Burton G. Malkiel loses clarity, especially in the fourth section. And that is very important to me in books.
Basically, the fourth section is intended to be a practical guide for investors taking the random route. The author promises concrete advice and recommendations for the various phases of life. But in the end, there is not much more than rough guidelines with exceptions upon exceptions.
For me, this drags the whole book down a level - unfortunately completely unnecessarily. In the first sections, the author provides so much scientific evidence for his critical classifications. That's why, at least from my point of view, you can demand a clearer stance from him at the end. Especially if you take a rational and scientific approach, you should, in my opinion, take a clear stance against irrational behavior. Unfortunately, the author does not do this.
Instead, numerous example portfolios and potential investment opportunities are shown, without any real ranking or clear recommendation or orientation.
At this point a few words about the author:
Burton G. Malkiel is a renowned US financial economist and author. He is known for his pioneering work in the field of finance and earlier editions of this book. Born on August 28, 1932, he has had an impressive academic career.
He graduated from Harvard University and obtained his doctorate in economics from Princeton University. He also taught there for decades and was a professor of economics. He was also a member of the board of the Securities and Exchange Commission (SEC).
Through his writings and teaching, he has had a lasting influence on the financial sector and investment philosophy. He is known for his clear, easy-to-understand explanations of complex financial concepts. And he has consistently advocated a rational, evidence-based approach to investing. Burton G. Malkiel remains an important figure in the world of finance. He has encouraged numerous investors to pursue a long-term and sensible investment strategy.
"On Wall Street, random walk is a dirty word. The term, coined by academics, is hurled insultingly in the faces of professional fortune tellers. Taken to its logical extreme, it means that a blindfolded monkey flinging darts at a price chart could put together a portfolio in this way that performs no worse than one constructed by the experts.
But the financial analysts in their pinstripe suits don't like to be compared to bare-assed monkeys."

Nevertheless, it remains a very good book because the first three sections are more than worth reading, comprehensive and well-founded. They provide a solid understanding of the important basics of investing. And they show how investors can sometimes achieve better results with less effort than experienced stock market players. Namely, by relying on clever and broad diversification, well thought-out portfolio management and a consistently passive investment approach. This requires a long-term planning horizon, patience and a thick skin for short and medium-term price fluctuations.
For the anniversary edition, current developments such as the Bitcoin bubble, robo-adivsors and "new" investment strategies such as factor investing and risk parity were included. I would like to praise this. This book was first published in 1973 and has been updated in several editions. It is still considered a classic in the field of financial literature.
"Fifty years have passed since A Random Walk Down Wall Street was first launched. The original edition's investment recommendation was simple: investors could achieve significantly better results by buying and holding a broad-based index fund rather than trying to buy and sell individual securities or actively managed mutual funds. I boldly claimed that any information affecting the prospects of individual companies would quickly be reflected in the prices of their shares.
Under these circumstances, a blindfolded chimpanzee throwing darts at a price list could select a portfolio that would perform just as well as one put together by experts. Of course, the recommendation was not to actually throw darts. The more appropriate analogy anyway would be not to look at the price list at all and to hold a portfolio made up of all the stocks represented in a broad stock market index. Such a portfolio is likely to outperform professionally managed equity funds, whose high annual fees, substantial trading costs and taxation reduce investment returns. Today, fifty years later, I am even more convinced of my original thesis - and can back it up with seven-figure profits."

To summarize A Random Walk Down Wall Street a wonderful book for anyone interested in the capital markets. No matter what level of knowledge you currently have: The book will certainly not do any harm and will sometimes provide some exciting food for thought. A clear recommendation from me.
"Stock market professionals often claim that investing capital properly is too complicated for normal people. Nothing could be further from the truth. The best investment strategies are surprisingly simple."
