Trailing stops are a way to take the emotion out of investing, and gives you a discipline to follow so that you are in the market when the time is right and get out of the market before your losses are overwhelming.
While Sjuggerud uses a 25% stop-loss, ours is set at 8%. Anything higher than that would be too much loss to take, while anything lower than that would mean selling more frequently.
By having an exit strategy, your decisions will have reason and definition behind them and there will be no confusion for you.
