The Market Wizards series has taught me so much about trading – finance is a very opaque industry so any insight into the mindset and methodology of successful practitioners is immensely valuable.
This edition focuses on small-time (”retail”) traders who trade their personal accounts, rather than the hedge fund titans from previous editions (e.g The New Market Wizards). The message isn't that "anyone can trade" – the traders are clearly above average in many respects (e.g intelligence and discipline) and have put in years of their lives into mastering their craft. Rather, the point is that success in trading is not determined by pedigree, though in reality it’s easier to get a trading seat in the first place if you’ve got the right credentials.
Several of the stock traders in the book are poster children of Peter Lynch's One Up On Wall Street – they know that Wall Street traders have edge in some areas, so they instead keep their ears to the ground looking for their own edge. For example, Jeffrey Neumann made a fantastic trade on CBD drinks just by talking to the managers and customers of convenience stores; Chris Camilio succesfully traded Netflix stock by tracking social media chatter after the launch of Stranger Things.
Much of the wisdom here has already been mentioned in the previous books (for example, the importance of discipline and risk management). I think that goes to show that these traits are necessary conditions for success. But they are certainly not sufficient conditions! My main takeaway from this edition is that there is no formula for success in trading – you have to figure out your own approach. Exciting and daunting!
