I've been reading up on stop losses and the importance of them. But I'm wondering how they work in the real world. (ok.. that probably sounds dumb). Say today, with just about everything on my watchlist falling.. Would you guys have cut your losses and sold? Or do you allow for these 'bad days' and if you know your stock well enough, ignore the stop loss and hold onto it awaiting a rebound? At what point is this following emotion.. or making a clean decision?
