i have read a lot about letting your profitable stocks keep running and selling your losers before eroding too much capital, and agree with the concept.
but how do you decide when to sell the profitable stocks ?
do you sell half at some point ? do you use a trailing stop ?
take MEO as an example bought in 11 weeks back, more than tripled in price, believe price will go higher in coming weeks, day traders trading around 3% of stock some days with trading ranges around 10% most days
when it is this volatile, but you believe in the stock what do you do ?
Normal Psychology, when this volatility is about, kicks in and says sell, but the psychology of investing says buy low sell high eg. dont panic
any thoughts from others ? both newbies and experienced
