Extraordinary Popular Delusions and the Madness of Crowds – A Key Book for Financial Freedom

extraordinary popular delusions and the madness of crowds

A crucial skill as one works towards financial independence is identifying and avoiding speculative bubbles. Spotting bubbles is not as easy as one might imagine, but here are a couple of indicators I have noticed over the years:

  • Massive hype around an emerging technology that is reshaping society. Yes, the changes wrought by such a technology will likely be real. Nevertheless, the stock of any particular company may collapse during the process.
  • Acquaintances with only passing interest in technology or investing become irrationally excited about the trend.
  • The press trumpets the technology and companies as earth shaking; the press sees no end to the trend (whatever it is). (The press is in reverse mode when certain sectors or commodities collapse.)

There is a book that will help you learn to spot bubbles. Charles Mackay's Extraordinary Popular Delusions and the Madness of Crowds explores speculative manias that transfix entire societies. First published in 1841, the book remains a compelling and hilarious read.

Extraordinary Popular Delusions and the Madness of Crowds - Your Antidote To Speculative Fevers


I first encountered Mackay's work during the manic tech boom of the late 90s while I was working as a stock broker at Charles Schwab. Reading about the South Sea Bubble at night and then going into work and watching Yahoo stock double yet again with a P/E ratio north of one thousand, Mackay's book served as an inoculation against the insane valuations and price action I would witness day in and day out. It was clear that technology share prices were disconnected from reality in the late 1990s, but it was not clear--to me--what would happen. I was young. I simply avoided the game and plowed my funds into broad-based index funds. I witnessed a similar bubble dynamic in real estate in the Washington DC area while living in Northern Virginia in 2006.

A Few Choice Quotes From Extraordinary Popular Delusions and the Madness of Crowds 


Here is an example of Mackay's prose and perspective from the preface:

"In reading the history of nations, we find that, like individuals, they have their whims and their peculiarities; their seasons of excitement and recklessness, when they care not what they do. We find that whole communities suddenly fix their minds upon one object, and go mad in its pursuit; that millions of people become simultaneously impressed with one delusion, and run after it, till their attention is caught by some new folly more captivating than the first. We see one nation suddenly seized, from its highest to its lowest members, with a fierce desire of military glory; another as suddenly becoming crazed upon a religious scruple; and neither of them recovering its senses until it has shed rivers of blood and sowed a harvest of groans and tears, to be reaped by its posterity."

And here is Mackay commenting on the state of England during the height of the South Sea Bubble in the eighteenth century:

"During the progress of this famous bubble, England presented a singular spectacle. The public mind was in a state of unwholesome fermentation. Men were no longer satisfied with the slow but sure profits of cautious industry. The hope of boundless wealth for the morrow made them heedless and extravagant for to-day. A luxury, till then unheard-of, was introduced, bringing in its train a corresponding laxity of morals. The over-bearing insolence of ignorant men, who had arisen to sudden wealth by successful gambling, made men of true gentility of mind and manners blush that gold should have power to raise the unworthy in the scale of society."

Mackay also does a fine job documenting how the public flips from avaricious mania to baying for revenge and seeking out villains and scapegoats when a bubble collapses.

Reading Extraordinary Popular Delusions And The Madness Of Crowds early in life was extremely helpful to me by providing the perspective that an entire society's judgment can go woefully wrong. That's why it's one of the key books I recommend on the path to financial independence.
