Parts of the book are only relevant to the USA, but the core message applies to everyone. This books main theme is supporting index investing and not to try too much in stock picking. Alot of it makes sense specially how the author presented his recommendations with historical data. This books content and narration was straightforward to understand and paves the way to get you started on your investment journey.

The author provides premise, data, and conclusions for his theories based on decades of work. the author mentions so many interesting ideas and even though the book is a bit repetitive, the style and jokes make it very readable.

You should always test the opposite of what your theory stipulates. If you can reject the opposite, your theory is as supported as it can be . The finance profession in their ignorance of philosophy of science tested it the other way around. This means that they could too easily conclude that the markets were efficient. I would say that the author is less critical of research that supports his preconceived opinion. While this book is potentially a great asset to the ‘ordinary’ reader, it is very heavy on the use of investing vernacular.

Include US stocks, international stocks, emerging market stocks, REITs, bonds, TIPs, and cash. Currently a lot of academics are questioning the efficient markets. I am reminded of Kuhn’s comment that the new paradigm only becomes prominent when the old guard dies/retires. Furthermore, a lot of people with a PhD in finance start hedge funds to exploit anomalies in the market place instead of writing academic articles. Wouldn’t this be worth serious consideration by the author? For instance the role of emotions is totally disregarded by academic-finance number-crunchers.

The reason, say Lynch and Rothchild, is that the basics of investing aren’t taught in school. At a time when individuals have to make important decisions about saving for college and 401 retirement funds, this failure to provide a basic education in investing can have tragic consequences.

A former attorney, before becoming a journalist Eric worked in securities litigation and white collar criminal defense with a pro bono specialty in human trafficking issues. He graduated from the University of Michigan Law School and can be found any given Saturday in the fall cheering on his Wolverines.

Sharp and Malkiel concluded that, due to the short-term randomness of returns, investors would be better off investing in a passively managed, well-diversified fund. A controversial aspect of Malkiel’s book theorized that “a blindfolded monkey throwing darts at a newspaper’s financial pages could select a portfolio that would do just as well as one carefully selected by experts.” The book popularized the efficient market hypothesis , an earlier theory posed by University of Chicago professor William Sharp. The efficient market hypothesis states that stock prices fully reflect all available information and expectations, so current prices are the best approximation of a company’s intrinsic value. This would preclude anyone from exploiting mispriced stocks consistently because price movements are mostly random and driven by unforeseen events. Random walk theory suggests that changes in stock prices have the same distribution and are independent of each other. Therefore, it assumes the past movement or trend of a stock price or market cannot be used to predict its future movement.

However, the experts were only able to beat the Dow Jones Industrial Average in 76 contests. Malkiel commented that the experts’ picks benefited from the publicity jump in the price of a stock that tends to occur when stock experts make a recommendation. Passive management proponents contend that, because the experts could only beat the market half the time, investors would be better off investing in a passive fund that charges far lower management fees. This book was a bit different than I expected it to be.

Pros And Cons Of Random Walk Theory

Underpinning the main thesis of A Random Walk Down Wall Street is something called the efficient market hypothesis. The idea is that the public stock market is a big place with fierce competition. Because so many people are trying to make favorable trades all day long, stocks are almost always priced fairly. But again, keep in mind that Malkiel is talking about the implications for individual investors who are buying stocks, not professional investors , and not foreign exchange or commodities traders. Technical analysis, practiced by “technicians,” uses the past price movements of stocks to determine where stocks will go next, while fundamental analysis looks at a company’s business to determine if its stock is properly valued. Technical Analysis – This approach to investing holds that you can profit by analyzing the price of a stock relative to its historic price and the prices of other, similarly situated assets.

So his asset allocation recommendations are the meat of his 2015 advice. Many readers may want to zoom right in on those later chapters. He has comments on the amount of risk appropriate to various situations. At times I wondered who Malkiel was directing the book at. Some of his advice is remarkably simplistic, the kind of advice only a newbie would need.

The papers can cover an extremely wide range of topics and assistance in topic selection will be available. I just finished reading the ’95 edition and am looking forward to reading the updated version. I had always dismissed this book as an absurdity based on the understanding that it espouses the strong approach. It most assuredly does not.He begins the book talking about historic market bubbles and their eventual collapses as examples of ineffecient markets. So in the absence of this information, how is one to invest over the long term? Mainstream media latches onto the stock indexing approach as though it was the sole method espoused by the author. Malkiel’s book is built on the premise that the stock market works efficiently, and investors should capitalize on this efficiency instead of killing their time and wasting their money trying to exploit the inefficiencies in the market.

Random walk theory argues that there are no such relationships known. Most proponents of the random walk theory apply it to short- and mid-term trading.

The company did quite well in 2019, but to have invested in that success a trader would need to have held onto the stock for months at a time, if not the whole year. One of the few books about financial markets and investing, covering the essential parts and providing a lot of useful guidelines, ideas, and information about the former topics. All mentioned investing strategies and ideas are described with their advantages, disadvantages, and some examples which is very helpful for beginners in those fields like me. Also, the book is updated regularly and the author includes some of the recent examples in our times such as the Real Estate bubble and others. I’ve been wanting to gain more understanding of investing and the stock market, and this book was a good place to start. I utilized the 2012 book (cause that’s what the library had), and while I would have preferred the most recent addition, it was still very useful.

I am embarrassed to admit that I was a fairly ignorant investor as I blindly on a monthly basis put my money into a 401k . With this book I was able to decipher what was before unintelligible and understand where my money was going. As it turns out the index fund is based on an appropriate lifecycle and also developed mkts which is good. I now have more confidence to take small portion of a cash and buy other index funds that are not represented in my portfolio like Reits developing mkts, etc. The only reason that I did not give the book a 5 is that at times he can become very quantitative and numerical which is difficult to follow in an audiobook. Finally, the narrator was outstanding as he lent the right amount of gravitas mixed with good humor to the narration.

While most of the course will be about U.S. markets, there will be some discussion of global and emerging markets.

  • If a spectacular deal exists, it will be instantly exploited until it’s gone.
  • For a person that is trying to learn about the market, this book is extremely difficult to understand by only hearing at it.
  • In the short- and mid-term, a stock’s price doesn’t have any known relationship with either its historic value or the value of any other assets on the market.
  • Possibly not for the complete beginner but the best place to come after getting mixed up trying to follow stock tips or get-rich-quick advice.
  • But if you’re already receptive to those ideas, you may prefer a book with more directly applicable advice, like The Simple Path to Wealth by JL Collins.
