Despite current earnings and U.S. dollar headwinds, the stock market is in the middle of a long expansion that could last until 2020, equity strategist Adam Parker said on Tuesday.
That would make it the longest expansion in history, he noted.
"You've got to have some reason that's going to cause the market to decline," Parker said in an interview with "Closing Bell."
To make that top of the cycle call, "it has to be that the economy rolls over, corporate arrogance grows and they put costs in place that aren't merited, or the credit cycle deteriorates."
Right now, he likes energy stocks, noting that they must be bought two to three months before earnings revisions bottom.
"You cannot wait for Brent to go up, the analysts to raise numbers and then I buy the stock. We know that's too late," he said.
He also thinks the valuations for oil services companies and exploration and production companies are starting to look "pretty compelling."
"I think it's time to get in there. Capital spending reductions are the catalyst," Parker said. "I still think Brent can be higher in two or three years and unless that changes, I think I can stay involved in the energy sector."
