Craig Johnson, chief market technician at Piper Sandler, is avoiding the group.
"We're underweight the sector," Johnson told CNBC's "Trading Nation" on Friday. "We're just seeing absolute price moves up but poor relative performance against the rest of the market. In fact, I find areas inside like the equipment makers more constructive than either the pharma names or the biotech."

The sector also looks cheap relative to the market, he said. The XLV ETF, for example, trades at 17 times forward earnings – the S&P 500 trades with a 20 times forward multiple.
"With interest rates low, with the demographics that we have and with people being so dependent on the pharmaceutical space, we just see that there's much more upside than not and especially coming off [being] the laggard," he said.
