Maybe for you - mentally, but it's not always the worst thing. If something drops and you know it's going to keep going down and down forever there is no reason to hold it. You can't always wait forever for it to bounce back.. Some things never bounce back.

Your money always needs to be working for you. Sometimes we make mistakes and invest in the wrong thing. There is no shame in moving that money out .

And this isn't an attack on "holding". The majority of my investments are in a hold strategy.
