Las Vegas Sands Corp. (NYSE:LVS) surged in early trading, only to give it all up into the close. The stock hit a new 52 week high early and then was blasted lower as the markets fell on worries about the debt ceiling. The stock is extended and finally today has put in a topping tail. A topping tail is a technical signal of a top. Look for downside in the coming days. It is interesting to see this sell signal appear just days before Las Vegas Sands releases earnings on Thursday, October 17th, 2013.
