I really enjoyed listening to Nicolas's story. A bit of luck launched his investing career. Repeated failures almost ended it. Determination, self examination, and lots of hard work led to eventual success and a repeatable method to consistently make money in stocks.
As I listened to the story, I could see elements of Reminiscences of a Stock Operator by Edwin Lefevre, Market Wizards by Jack Schwager, Rule #1 by Phil Town and How to Make Money in Stocks by William O’Neil. What Nicolas discovered was that to make money in stocks, he needed to 1) find the right company and put it on a watch list; 2) wait for the stock price to start moving up before buying in; 3) always protect the downside by placing a protective stop, 4) sell losers and keep winners; and 5) sell when the price stops going up.
Nicolas's “box” method is very close to the Turtle trading method. It can work spectacularly well, but it does require discipline. He made money as long as he remained disciplined. He lost money when he failed to be disciplined. Excellent story, great message, I highly recommend this listen.
