What Blackjack and Gambling Teach Us About Investing

Chapter 17 starts with a confession that always gets Wilmott in trouble with bank training managers. He wants to call his lecture “Investment Lessons from Blackjack and Gambling.” They want him to change the title because regulators might frown on it. Wilmott thinks this is silly. Investment and gambling share the same mathematical roots. And most professional gamblers he knows understand risk and money management better than most risk managers at banks.

Why People Trade: The Real Motives Behind Market Activity (Chapter 8)

Here is a question that sounds simple but almost nobody answers honestly: why do you trade?

Not “to make money.” That is what everyone says. Harris dedicates Chapter 8 to pulling apart all the different reasons people actually show up to the market. And the taxonomy he builds is genuinely useful. Because if you do not understand why you trade, you are probably doing it wrong. And if you cannot figure out why the person on the other side of your trade is trading, you have no idea whether you are the smart money or the dumb money.
