Like most closed shops, the financial industry features its own specialized vocabulary. As an investor, the key to understanding the financial industry is to understand the buzzwords and special terminology that are as often used to obfuscate concepts as to illuminate investors.

All of which makes Jason Zweig’s The Devil’s Financial Dictionary an invaluable tool for serious investors. Zweig is of course the Wall Street Journal’s eminent personal finance columnist. The book, published late in 2015, was inspired by Ambrose Bierce’s classic book, The Devil’s Dictionary.

As Zweig writes in his book’s introduction, “If investors are to be partners instead of pigeons, they must master the many ways in which Wall Street uses language to conceal rather than reveal information. Every profession is a conspiracy against the laity, and every profession’s jargon is meant to confuse and exclude those who aren’t part of the guild.”

If you learn nothing else, consider the following pithy observation by Zweig:

The denser the jargon, and the more polysyllabic the terminology, the more likely someone is hiding something from you.

They’re also quite cynical, which is half the fun: I’m sure Zweig had a blast writing them up in the first place.
