If a leading stock on your watch list takes off and jets well past the buy point before you have a chance to react, be patient. Just as you don’t want to buy a stock prematurely, you shouldn’t chase it too far up in price, either. Chasing a stock increases risk — there will be little cushion to buffer a downturn. Instead, look for the proper buy point, whether from a base or on a rebound off the 50-day or 10-week moving average.
