From the September issue of the Astro Economics Stock Market Newsletter:
The two weeks after Labor Day are historically a slow
start in the markets. Then take-off! This past earnings
season was the best in a long time.
On page 2 of the newsletter under Buying and Holding Strategies:
Once you purchase a stock, place a stop order of 5% below the stock’s purchase price. Multiply the price you paid by five and subtract that number from the purchase price ($42 X .05 equals $2.1. Your stop order on that stock would be $40). Following this rule, you protect your profits and reduce losses.
