Bingo on both points Traderfan.
I would add I think Chen has probably had to change his trading style somewhat to more of a buy and hold style simply because there is only so much trading you can do with oil and mining juniors without moving the stock price by yourself. The more capital you have to invest/trade, the slower you trade in and out of positions and less frequently as well. The percentage gains per year probably slow down as well but dollar gains more than compensate for that.
I think he is a great stock picker and has great timing when he is free to move in and out of positions. But nobody hits on all of them. If you are getting 1 out of 5 or 6 picks as multibaggers, you can afford to pick some losers.
