I'm 'married' to US stocks: Fund manager

5-star ETF bets: Pro still bullish on US

The manager of an ETF-heavy fund is sticking to U.S. stocks as major indexes trade near records.

"I'm still very bullish, and we've dialed it up," Paul Frank, lead portfolio manager of the five-star Morningstar-rated Stadion Tactical Growth Fund, told CNBC's "Power Lunch " on Tuesday.

Managers of the fund, which primarily invests in exchange-traded funds, have grown even more confident in U.S. equities since last year. In mid-October, it stood at about 60 percent U.S. stocks, but has since climbed to 84 percent, Frank said.

Managers rank more than 1,300 funds and will "go anywhere there's a well-run ETF," he said. The fund is "married" to U.S. stocks and is overweight in mid-cap ETFs, Frank said. He sees upside in consumer staples and telecom, as well.

Frank holds a bearish stance on utilities and real estate investment trusts, which both enjoyed a strong 2014.

"We did well on the REITs last year, and we did well on the utilities in the beginning of the year. It's just seemed that people searching for that yield has kind of gone sour," he said.

He noted that if interest rates increase this year, the fund will move toward commodities. Frank added that Federal Reserve Chair Janet Yellen "the opposite of a loose cannon" and would give investors plenty of notice before the Fed hikes interest rates.
