We sometimes forget that… the line between crowd wisdom and crowd madness is a fine one. This book by Professor Edmans reminds us of that truth, and it is filled with useful insights for investors, while being fun to read. While many behavioural finance books are centered on how investor psychology can skew pricing, this book follows through by offering actionable advice on how investors can take advantage of these mistakes.

At a time when markets often seem to be going mad, amid wild AI hype, Edmans’ book offers a cool-headed compass that enables you to navigate the world of finance and - most importantly - your own emotions. Punchy, witty and provocative, this enables anyone to work out whether they are over or under-reacting to events, and chart a more level-headed approach to reading market signals.

This book serves two purposes: it is an incredibly useful and entertaining handbook - but it is also a warning. Numbers often lie - in large part perhaps we prefer it that way.
