Since his Wall Street days, Jim Cramer has used one foolproof strategy to reward his portfolio after major earnings announcements.

"On Monday, we hear from Kimberly-Clark and I've had the same view about this stock since my days at Goldman Sachs in the '80s. You buy Kimberly-Clark when it gets hit. This is a strategy that's never failed me, and I bet this time will be no different," the "Mad Money" host said.
