Apple’sMarket cap will rise above the $3 trillion milestone it hit brieflyAccording to one chief investor officer, Monday’s stock valuation was justified.

Patrick Armstrong, CIO, Plurimi Group’s investment management company Plurimi Group expects Apple’s share price will continue to grow faster than the entire economy. IMF predicts that the U.S. Economy will expand by 5.2% in 2022. global economy is seen expanding by 4.9%.

Armstrong stated Tuesday on CNBC’s SquawkBox Europe that “I don’t think it’s going to be an stock that’s going to go double very quickly.” However, he said that it will “grow quicker than the economy.”

Apple, the nation’s first publicly traded American company, reached $1 trillion in valuation on Aug. 2018. The market cap of Apple has increased by more than three times its value within four years.

Apple is a very positive company when it comes to cash flow, earnings, market share and profit margins. Armstrong stated that it’s nearly ideal when you consider all those metrics.

MicrosoftThe company is worth approximately $2.5 trillion. AmazonGoogle-parent AlphabetApple is valued at $1.75 Billion. Although some analysts question whether Apple’s stock is too high, Armstrong stated that the market capital of Apple’s iPhone maker is not as large as other companies.

He said, “It is an amazing company trading at premium multiples.” It’s not unusual for it to be that way. Great companies should be able to trade at high multiples. You don’t have to trade at the high multiples of some other companies, but I do not think so.

Armstrong claimed that he had sold Apple shares and then bought more in December during a dip.

However, not everyone is so bullish about Apple at the moment.

Emma Wall, head of investment analysis and research at Hargreaves Lansdown, told CNBC’s “Squawk Box Europe” on Tuesday that now probably isn’t the time for investors to buying Apple or Tesla shares.

“If they are already exposed, you can take some gains but it’s a good idea to keep them in a diversified portfolio.” she said.
