Divide the capital equally into 10 portions, each buying different stocks. If you are confident, you can buy multiple portions of the same stock. Once the gain exceeds 10%, sell it and switch to other stocks you are bullish on (then sell again after another 10% gain). As long as you capture 30 such 10% gains, one portion of capital can multiply by 17 times. Some capital might earn more due to good luck, while some might remain trapped due to bad luck. I call this strategy "Ambush from Ten Sides," only buying quality stocks, leading stocks, and stocks in promising sectors. How long will it take for this strategy to break even?
