Peter Tuchman says he's surprised to have not seen a significant pullback recently. However, the Einstein of Wall Street points to money on the sidelines still funneling into stocks as a reason for strength. One day of selling after a strong spree of up days doesn't signal concern to him, though he urges investors to stay on their toes. Peter believes an extended government shutdown can have a 1% impact to GDP — "a big move," according to him. He also remains a table pounder when it comes to A.I.'s future potential.
