The everything-you-know-is-wrong book of investing. Kenneth Fisher, veteran of countless investing books and Forbes magazine columns, presents the counter-intuitive world of investing as he sees it. He takes on nonsensical beliefs such as the year’s performance is determinable from January’s performance, that political outcomes or the Superbowl foretell stock market futures or selling in May is a good idea. Fisher easily dismisses these beliefs with statistics not that it takes much to overturn ...more

The book can be summarized, and in fact is summarized by the author midway through, with the thought that there is no one perfect measure or indicator -- if there was then everyone would use it to invest. The book consists of chapters of 50 common misconceptions about the stock market or economic statistics, things like better unemployment numbers yields better stock returns, or stock should be sold in May. Most of these are disproved by looking at historic data, at least disproving that the rul ...more

A collection of arguments against conventional stock market sayings, like sell in may, so goes January, Beta equals risk, P/E tells if a stock is cheap. Biggest takeaway is that stocks AVERAGE over time 10%. Volatility is to be expected, and volatility is both ways, (up and down). Additionally, behavioral finance theory states the losses hurt much more than gains for most investors called ‘Myopic loss aversion’. I tend to think the other way, lost profits hurt more than losing positions. Or at l ...more

I'm rather surprised by the low rating on this book by the other reviewer. Ken Fisher is one of the most successful and well regarded investment managers in the world. He is constantly on the prowl of proof of trends that matter, combinations of indicators that mean something, at least for a relatively short period of time. His description of 50 widely accepted Wall Street "truths" and his factual support for their fallability is excellent, even if the theme is repeated so often. Perhaps the oth ...more

My first Ken Fisher book. I thought it was a decent investment book. Premise is to debunk myths about investing. He is very gung ho on the stock market, and relies on straight forward analysis to make his point.

One of his points is to look at what makes up averages. One example is where he shows S&P 500 annual return ranges since 1926. Only 28.6% were there negative returns, 33.3% (28 occurrences) had average returns of 10-20%, and 38% of the time had returns greater than 20%. He also showe

When stopped at the bank or on the streets by financial advisors/planners trying to promote insurance policies or funds, I enjoy asking and listening to their basis for recommending any funds. The usual suspects are:

- Bonds are safer.
- This fund has low volatility.
- The size of this fund is hUuuge!
- You need to rebalance your portfolio to hold more bonds as you get older.
- This fund/market is not doing well, it fell by x% over the last 1 year, best to avoid.
- This fund/market is doing great, it

Fun easy read on common investing mistakes. Great for newbies, even a few thought provoking ones for me.

Ken Fisher has an excellent book here! I found the 50 “bunks” to be quite helpful. He makes you look at the stock market with new eyes not clouded by public opinion. The book is easy to follow and understand but I feel that it is not meant for a beginner. I think that it would be better if you knew a little something about investing in stocks and some basic facts about the economy before you read this book. However, I may be wrong. Maybe this is one of the first books that you should read so tha ...more
Nice little advanced-beginner material on investing and the markets. Broken into 50 small chapters that shows why some common sentiment is either taken out of context or grossly misrepresented. I read it in its entirety and in order, but it certainly does not need to be done that way.

I really liked the idea of this book, and feel the author did a great job with presenting information. Definitely something that should be read by a headline newsreader or a CNBC viewer.

This was a lot of fun. Easy to read in small pieces, but some great information, charts, etc. Couldn't find anything to dislike.
