The markets (^DJI,^GSPC, ^IXIC) experienced volatility this week as the S&P 500 (^GSPC) is seeing its fourth straight weekly loss. Yardeni Research President Ed Yardeni joins Yahoo Finance to discuss the market's volatility.

"Looking ahead here, I think we're going to continue to churn below the July 16 high," Yardeni explains. "The churn will probably continue through September, October, until the November elections. So I expect the market to kind of go sideways with a lot of volatility below that July 16 high. And then I think we could very well have a year-end rally, a Santa Claus rally."
