Since my $SAP (-0,88%) - Distaster, I have always been concerned with the question of how to deal with solid shares that have done well and how to secure profits if you actually believe in the company and therefore do not sell and pursue a buy and hold strategy.
I was at +120% with SAP and then didn't sell at 280 because it was doing so well. After the setback to €240, I thought, I won't sell now either, it will go up again. And now we are at 140 euros :-(
What do you do with stocks that have done well and that you actually believe in and want to keep? For example, I have $ALV (+0,03%) + 90% and I don't want to sell it because it's a solid share. But who knows, maybe something unforeseen will happen and then the profit will be gone. For example $NOVO B (+0,43%) many people probably missed the exit and are now at 25% of the peak price.
Do you have any ideas? I don't have the time to check and evaluate every report on every share every day, or I would certainly make the wrong decision. Simply selling via S/L can of course also mean selling in the event of a short-term fall, which may even be made up for intraday. And of course the question of where to set the S/L?
Thank you very much for your help!
