At times like these, one of the best choices investors can make is to put their money into safe stocks that can do well no matter what happens with tariffs and the global economy. One of the best candidates out there is AutoZone (NYSE: AZO), the aftermarket auto parts retailer that has trounced the market over its history, outperforming it by an even wider margin in bear markets.
