Stocks are down more than three-percent since November 4, when Federal Reserve Chair Janet Yellen said a December interest rate hike is "a live possibility."
But Scott Wren, senior global equity strategist at Wells Fargo Investment Institute, tells CNBC's "Power Lunch" on Friday market volatility is a buying opportunity.
"The Fed is going to be very careful and take it very slow. The Fed does not want to make a mistake. The Fed realizes it needs 2 or even 3 months to properly prep the market for a rate increase (exactly what they are doing now)," Wren said.
"We are encouraging our clients to take advantage of pullbacks and add to cyclical sector equity exposure," Wren said.
The consumer discretionary, information technology and industrials sectors are lower during trading.
