U.S. Investors Need to Look More at Global Markets: Strategist

U.S. investors need to change their mindset and move toward global market investment, according to Wachovia Securities Chief Equity Strategist Doug Sandler.

"We've reached the tipping point where global growth has gotten more important, particularly for sectors like the material and the industrial sector," Sandler said on "Squawk Box."

Despite global growth, U.S. investors still use the S&P 500 as the benchmark to measure market performance, which is only about 3% of the global index, he said.

As for current growth areas, Sandler suggested the drilling and service companies, utilities, and semiconductors to investors.
