btfd 8 times I have sold 25% of my holdings on the steep rise and 8 times I have bought back that same amount of shares on the dip. never timed the peak, never timed the bottom, but good enough. I trade that amount strictly on RSI. I have 7% more profit than if I held. I do it because it is fun! not because I am clever. this is my way of investing. each to his own. the point of investing is to make a profit. many differents ways to get there.
