Retail stocks have slumped this year.
"Amazon has been here for a long time - this is the worst year for retail - it's worse than 2008 and 2009," he said. "This is because consumers are broke - they have lousy jobs, they're loaded up with debt and they can't afford to buy stuff."
Schiff isn't comforted by the double-digit gains in earnings growth for the past two quarters in U.S. stocks.
"Let's see what happens if we go to a recession which is going to impeded [companies'] revenues and let's see what happens if interest rates finally rise despite what the Fed does and that's going to undermine their costs because you have a lot of companies that have levered up their balance sheets."
Schiff said companies have been resorting to debt-financed share buybacks amid low interest rates. "All that's going to come back to bite these companies when interest rates go up," Schiff said.
