NEW YORK (TheStreet) -- Members of high-performing tech group FANG (Facebook (FB) , Amazon.com (AMZN), Netflix (NFLX) and Alphabet (GOOGl)) are all retreating in early afternoon trading on Monday, as investors are concerned that President-elect Donald Trump will enact "anti-trade" policies. A number of other stocks have been rallying post-election, namely those in healthcare and financials.

The reason tech stocks are down so much is because that sector is acting like an "ATM" for investors looking to put money into sectors that are seeing a boost right now, Virtus Investment Partners Chief Market Strategist Joe Terranova said on CNBC's "Halftime Report" on Monday afternoon.

"Technology is being sold off. We're ringing the register and we're moving money into financials because there is this monumental institutional shift that is going on where money needs to go into the financials," he said. Trump is expected to decrease regulation in the sector, while Democratic candidate Hillary Clinton was expected to increase it.

When looking for money to put into the stocks that are rallying post-election, investors go to where there's been profits and that is "absolutely" the tech sector, Terranova said.

The question now is, "How long do you believe this rotation is going to go on for?" he noted. In his opinion, the rally that began after the election last Tuesday is coming to an end because rallies usually last from seven to 10 days.

Long-term investors want to buy these tech names right now because they know these stocks will "be okay in the long run," Terranova pointed out. "But if you're being tactical it might not be the moment just yet."
