Cramer's game plan: Overvalued IPOs can dim a positive earnings season

"If we get a few more of these red-hot, yet hopelessly overvalued deals ... the averages will start to feel the pressure," CNBC's Jim Cramer says. "Even as I expect some terrific quarters buried in next week's cacophony of earnings reports, call me wary," he says. Thursday's session signaled that the market is "getting genuinely overexuberant" and the major averages could become wobbly if more IPOs become overvalued in the near future, CNBC's Jim Cramer said.
