Katie Stockton with Fairlead Strategies notes a strong trend to the upside seen in indices and sectors — all without a significant pullback. That lack of a pullback has Katie concerned when it comes to holding the rally. She sees signs of "exhaustion" that can open the door to strong selling action if market leaders like tech exhibit weakness. Katie later talks about gold's nosebleed run and the U.S. dollar's potential to rebound to $100.
