Clear opportunity to invest in US stocks: Pro

Stocks will move forward despite the recent volatility because the technicals are still in place for a good market environment, self-proclaimed perennial bull Carla Harris told CNBC on Wednesday.

"You have record low interest rates, a lot of cash on the sidelines, which makes for a great M&A environment, and you still have company performance—so far, knock on wood, as you've seen fourth-quarter performance starting to come out, the data is good," Harris, vice chair of global wealth for Morgan Stanley, told "Power Lunch."

Harris, who is also the author of the book, "Strategize to Win," and chair of the National Women's Business Council, believes there is a clear opportunity to invest in the U.S. market. While she wouldn't jump into Europe, she said there are some "opportunistic spaces around the world."

"If you have the stomach for it, I think there's enormous opportunity in Europe but there's still a lot of uncertainty, so therefore we're likely to see some downward pressure continue," she said.

She advises investors to be productive and constructive in picking investments. "Know your spots … and be opportunistic about it."

Ben Willis, senior floor broker with Princeton Securities Group, is also still bullish on the market but warned that volatility will continue for a "significant period of time."

"We are going through the great unwind. Every central bank in the world is going to have an impact, three-digit moves in the Dow," he said.

He also believes oil prices are not finished falling thanks to unprecedented supply but believes it will bounce from the $40-$45 level.

That is offering some trading opportunities, Willis said.

"I don't know if you want to start a new position right now in the energy stocks, but you need to have your pencil ready to see where the value has been destroyed because people don't understand what's there," he said.

Kevin Caron, portfolio manager at Washington Crossing Advisors is sticking with U.S. stocks, although he's not expecting returns this year to be as high as they were in 2014.

He likes large tech, health care and would start to put together a shopping list for energy.

"Looking out three to five years from now, I think there are a lot of decent values to be had. You've got to be patient, though," Caron said. "There's still a lot of volatility there. We may not be done to the downside."
