The Dow Just Jumped 1,100 Points. Here's What Warren Buffett's 2008 Rule Says to a 66-Year-Old Retiree Who Almost Moved $600,000 to Cash on Friday

The Dow jumped about 1,100 points on Monday after stocks' worst week since April, while the worries behind the selling were still there. Warren Buffett's 2008 rule for that moment is one sentence long, it cost its followers 26.9% before it paid them 85.8%, and for a retired couple with $1.8 million it turns a $600,000 sell order into one number.
