The Efficient Market Hypothesis

Each chapter starts with, I guess, a personal story and then relates that to an event or trend in the futures markets. There's one about your dad thinking he's a great trader and not actually being one. And your mum turning out to be a really good trader and still going at it. This brings me on to this journey of kind of the understanding of the efficient market hypothesis - idea that you can flip a coin and the results of that seem to map quite clearly onto the day to day trading of stocks or futures in eggs and so on. Can you just take us on that, J.D., because I found that bit particularly fascinating?
