I hope for your sake that you didn't get stopped out @ 38 1/4 on Friday! Walgreen is in the middle of another leg up here. Why would you place a stop loss order so close to the current selling price anyway? You run the risk of getting bumped out of the stock on a slight (in your case, very slight) dip in the price. A more reasonable place for a stop loss order is 12-15% below the price you paid for the stock. Then, as the price rises, you can move the order up with it. Also, I would avise beginners NOT to watch the stock as closely as you say you are. It will drive you nuts trying to figure out the irrational moves in the price of your stocks and the market as a whole!
Good advice. Too many people get caught up in the day-to-day movement of stocks. Because there has to be a buyer for every seller, sometimes things get out of whack. A good stock like WAG continues to grow over time. I bought 500 shares initially about 4-5 years ago; I now own 2,000 shares because of splits and the value today is worth over 4 times my original investment. You're right on - buy and hold for the long term. THAT'S WHERE THE MONEY IS MADE.
