Gene Goldman compares the market to the football pre-season. He says ballooning valuations and thinning market breadth make Wall Street look weaker on the outside, though Gene says this is still a "buy the dip" market that will lead to strength down the road. He expects small and mid-cap companies to do very well, along with certain A.I. and cybersecurity firms. As for the Fed, Gene explains Jerome Powell's "wise owl" approach ahead of Jackson Hole.
