Comprehensive Summary of the all time best book  on Investing One Up on Wall Street by Peter Lynch (1989)

One of the most famous books on investing is "One Up on Wall Street" by Peter Lynch. The book, first published in 1989, is a timeless classic that provides practical advice for anyone interested in investing in the stock market. Lynch, who achieved great success as a fund manager, shares his insights and experiences to help readers become better investors. In this article, we will take a closer look at "One Up on Wall Street" and explore its key themes and insights.

One Up on Wall Street by Peter Lynch (1989)

This is the first book written by the legendary portfolio manager at Fidelity, Peter Lynch, whose Magellan Fund generated 29% annual returns during the 1977-1990 period. The latest edition has an introduction written at the peak of the Dotcom bubble, which allowed Lynch to share his perspective on the tech stocks. I view this book as a must-read investment classic even for those who have spent a few years in the markets.

Behind every stock there is a business

The core of Lynch's investment philosophy, which is discussed in the book, is that 'behind every stock, there is a business' and, thus, the performance of a stock would ultimately reflect the performance of the business, namely earnings dynamics. Lynch reiterates a few times that understanding business prospects through first-hand knowledge of a particular product (that you may be consuming every day) is the key to success. Trying to time the market or spend time thinking about future market direction is a waste of time, according to the investment guru.

The book focused on three main ideas: 

 

1) Personal circumstances before you start investing

2) How to find the best investment ideas

3) Portfolio management

 

 The main investment tool introduced by Lynch is the six categories of investment cases for various companies, which help to decide on key issues to focus on in each case as well as make decisions on when to buy and sell such companies. It also helps in portfolio management deciding on specific weights for each stock. The book also has a few useful checklists for best companies and typical mistakes in investing. Finally, another very useful analytical tool introduced by Lynch is the share price vs earnings chart, where two lines for each indicator are put together (when share price significantly deviates from the earnings line, it is normally a signal to buy or sell the shares).

The first part highlights that you should allocate that part of your savings that you don't need to spend for the next few years and could even afford to lose, and it is better to own a property where you live before you start allocating a significant part of your capital on stock investments. Lynch also emphasis's that a person has to have certain qualities to be a successful investor, including making decisions with incomplete information. Other key qualities include patience, common sense, self-reliance, a tolerance for pain, open-mindedness, detachment, persistence, humility, flexibility, willingness to admit mistakes, ability to ignore general panic.

An amateur has a few advantages over professional investors, according to Lynch, not only because he/she is not constrained by formal rules policies and can be more flexible with the weights for individual stocks, but most importantly because an amateur can focus on real products around him that either he enjoys and are popular with his friends and act quickly (after doing his own research first). As long as the valuation is reasonable and the balance sheet is not stretched, companies with great products would likely end up generating strong earnings growth pushing prices for their stock along the way.

This section of the book also has a short summary of key behavioral challenges as every investor passes in and out of three emotional states: concern, complacency, and capitulation. He's concerned after the market has dropped or the economy seemed to falter, which keeps him from buying good companies at bargain prices. Then after he buys at higher prices, he gets complacent because his stocks are going up. This is precisely the time he ought to be concerned enough to check the fundamentals, but he isn't. Then, finally, when his stocks fall on hard times, and the prices fall to below what he paid, he capitulates and sells in a snit.

Lynch also notes that there is always some uncertainty and no one should expect to be right with his stocks all the time. It is important to be prepared to take occasional losses. Lynch compares investing to a poker game where you win over time following the right method as opposed to winning in each round. Related to idea to this thesis on uncertainty is Lynch's advice against trying to time the market and his preference for always staying in the market. He refers to the last five years before the second edition of the book saying that if you missed the best 30 days since 1994, your returns would be half of what you could have earned staying fully invested throughout the period.

One final idea discussed in the first part of the book is that stocks offer best long-term returns compared to other asset classes. I have a post on this point in my Notes on investing where I highlight that while stock market index may outperform all other asset classes, more than half of individual stocks actually lose money, so it is an important warning against simply buying 5 stocks and expecting to achieve great investment results.

Two other sections of the book are, perhaps, the most interesting for a practising investor. To find a multibagger (a stock that delivers multiple times returns), you should try to find fast growing companies and of relatively small size. Looking around you in shopping malls (Internet, these days) can be the starting point. Your job, hobbies or hobbies of your children can be of great help to identify companies who products or services are just becoming popular as long as the market has not discovered this yet.

The book is divided into 10 chapters, each of which explores a different aspect of investing.
