Stocks are selling off on Tuesday due to rising uncertainty about the presidential election. But one market veteran says health care can perform well under a Clinton or Trump presidency.

Heartland Financial Chief Investment Officer Nancy Tengler tells CNBC's Power Lunch on Tuesday she believes the sector is oversold.

She has been adding to health care on dips and one of her top picks is medical device maker Medtronic.

Tengler also sees opportunities outside of health care.

"Technology remains a modest overweight and we continue to add to holdings," Tengler said. A name she likes in tech is Harris Corporation.

Medtronic is lower during trading, while Harris is higher.
