We hold 400 shares purchased overnight Tuesday at 50.40. Since the stock could fall to as low as 48.10 if it breaks down here, set a stop-loss at 49.94.  You should plan on re-buying at 48.15, no stop, good-till-canceled.  I’ve included a chart that shows night-session price bars on the 5-minute chart.  ______ UPDATE (11:56 a.m EDT): Raise the stop-loss to 50.18.
