Here's why I would recommend against [selling the U. S. stock markets short].... Retail brokers normally require investors to hold any short-sale proceeds in U. S. dollars, usually earning no interest. The dollar, seen through my famously jaundiced eye, could lose more purchasing power than the security you sold short lost value.... I've got a much better idea, which is to borrow dollars and spend them to acquire foreign income-producing assets, using the income to pay the interest.
