The Missing Billionaires A Guide to Better Financial Decisions

"...a smart and sophisticated primer on quantitative risk-management techniques."
-The Wall Street Journal

"A compelling book dealing with an important and neglected question in finance: not what to buy or sell, but how much. Even sophisticated professionals tend to answer this question badly, leading to lost fortunes. But financial theory provides the answer. Mathematical but not excessively so, this will appeal to anyone with an interest in markets."

"The most important investment decision is not 'what' but 'how much.' If you ever hear a professional investor talk about a trade that taught them a lot, prick up your ears. Usually, this is code for 'a time I lost an absolutely colossal amount of money,' and you are in for one of the better stories about how finance works at the coalface. On this front, Victor Haghani is a man to whom it is worth listening. Now, along with his present-day colleague James White, he has written a book that aims to spare other investors his mistakes . . . The Missing Billionaires . . . examines what its authors argue is a much more important-and neglected-question than picking the right investments to buy or sell: not 'what' but 'how much.'"
