Have a look at your trades over the past 12 months. How many of those, if you hadn’t sold, would still be gaining value? If the answer is none or just one or two, you are right in the sweet spot. But if the answer is more than that, you might want to reassess how you apply your sell rules. To be sure, most stocks, when sold correctly, will continue to gain ground for at least a short while. That is exactly what you want.
