Falling oil prices and growing consumer confidence should benefit some companies in the mid-cap space in 2015, a mid-cap fund manager said on Wednesday.
Among other mid-cap companies, JetBlue, Pilgrim's Pride and Mohawk Industries may cash in on the trends, said Brian Peery, co-portfolio manager of the Hennessy Cornerstone Midcap 30 Fund.
"I think it's kind of the sweet spot of the market," Peery told CNBC's "Closing Bell."
The Hennessy fund defines mid-cap companies as those with a market cap between $1 billion-$10 billion. It outperformed the benchmark Russell Midcap Index in the last year. Recent economic trends have increased the allure of certain mid-cap sectors, Peery said.

In particular, Jet Blue's appeal stems from sliding oil prices, he said. He added that Mohawk Industries should see a boost from elevated consumer sentiment, which hit a nearly eight-year high in December.
"I think that [2015] is the year where the consumer kind of opens up their purse book and starts spending, and spending on stuff that they've deferred over the last couple years. I think Mohawk is going to be a winner in that," Peery said.

For investors who believe the market is currently overvalued, Pilgrim's Pride is a safer pick, Peery noted.
