Warren Buffett: Currencies

“We don’t understand what currencies are going to do week-to-week or month-to-month or year-to-year. And we always try to figure on what — focus on what’s knowable and what’s important. Now, currency might be important, but we don’t think it’s knowable. Other things are unimportant, but knowable. But what really counts is what’s knowable and important.” 

—Warren Buffett.
