RE:Taking Profits Is A Good Thingfor me there a couple of reasons it doesn't work. First, I never time it exactly right. I would have sold the day before yesterday and missed the big rise.
Second. all those short term purchases and sales are a tax mess to report. I prefer just to stay long term as long as the story looks good. I might need to reduce my holding at some point in the future because I have a house to build.
