Do not get emotional about a stock. If the stock is working, let it work. If it is not, ditch it. Think like an employer. The employee with the highest productivity should be promoted and given a raise. The lazy employees should be fired and sent on their way. Trading is no different. The stocks that are working well are the stocks to be cherished. Add to your position to increase your profits. Stocks that are not working are your bad, lazy employees. Fire them quickly and move on.
