Nancy Tengler argues that Apple (AAPL) is a stock you "want to hold" and "buy on weakness." She considers Apple the "U.S. treasury bill of technology" that will be proven in part through Tuesday's "awe dropping" product event. She adds that the antitrust ruling for Alphabet's (GOOGL) Google Chrome can open the door for joint A.I. ventures between both companies. Scott Kessler says Apple is in a better positioning for A.I. now but still has a lot to prove when it comes to capitalizing on the tech.
