Cramer's Game Plan: Remember this market 'has no memory' this earnings season

"Even though earnings season kicked off with an amazingly bullish bang, we'll be right back where we started from once next week rolls around," CNBC's Jim Cramer says. "In the cacophony of earnings reports next week, remember that this market has no memory," the "Mad Money" host says. The major U.S. indexes all rallied Friday on the backs of Walt Disney DIS , J. P. Morgan Chase JPM , and Chevron CVX , but CNBC's Jim Cramer warned that "this positivity" will be hard to sustain.
