Barstool Sports founder and mouthy trader Dave Portnoy got plenty of heat last month for calling Warren Buffett an “idiot” after the Berkshire Hathaway boss unloaded his airline stocks and missed out on a big rebound in the beaten-down sector.

According to Shane Parrish of the popular Farnam Street blog, that’s all part of the plan: "You have to be willing to look like an idiot in the short term to get the best long-term results. I’d suggest that because the future has become increasingly uncertain, he’s preparing for the widest range of possible futures."
