Jim McTague devotes his latest “D.C. Current” column in Barron’s to expert advice about the likely impact for investors of upcoming political events.

Oh my! Look what’s on your fall calendar: American involvement in another Middle Eastern war and yet another bitter clash on Capitol Hill over the debt ceiling.

We’ve been warned about this over and over, and we all remember how similar events caused wild swings in the markets in 2011. Yet based on my e-mails, some of you are groping for a survival strategy.

… [Mark] SPITZNAGEL, A MATHEMATICIAN and the author of the Dao of Capital: Austrian Investing in a Distorted World, is one of the great contrarian investors to emerge from the 2008 market crash.

Since then, he has been betting that the stock market, which has been pumped up by the Federal Reserve’s easy-money policies, will fall 40% or more when the stimulus is removed. He expects that to happen in a year or so.

Spitznagel’s firm hedges with derivatives and other exotic investments. His advice for retail investors is simply: “Move into cash, as painful as that might be” and “focus on opportunities that lie ahead, rather than focusing on the opportunities du jour, like dividend-paying stocks.”
