Just look at FANG go. The acronym stands for Facebook (FB) - Get Report , Amazon (AMZN) - Get Report , Netflix (NFLX) - Get Report and Alphabet/Google (GOOGL) - Get Report .

The group just continues to power higher, TheStreet's Jim Cramer noted on CNBC's "Stop Trading" segment. He pointed out that Facebook -- just days after seeing its stock tank after investors feared its plans to change its News Feed would hurt ad revenue -- is less than $1 from breaking through its all-time high of $188.90.

The company is trying to keep its platform relevant even as its Instagram property continues to churn out growth, he reasoned.

Additionally, Netflix has continually found way to reinvent itself. And while it may be spending upward of $8 billion on content this year, investors don't have a worry in the world right now. Shares are soaring 10% Tuesday, smashing through old highs and setting new all-time marks in the session.

Netflix now commands a market cap of nearly $110 billion.

Cramer pointed out that Microsoft (MSFT) - Get Report now has a market cap in excess of $700 billion, while Alphabet has eclipsed the $800 billion mark.

When investors think of FANG and the holidays, they generally think of Amazon as the big winner. And while Amazon, which is hitting new all-time highs as well Tuesday and now has a $651 billion market cap, surely had a tremendous holiday season, investors need to think of Alphabet as a holiday name too, Cramer said.

The search giant's data-center business likely enjoyed a good quarter, while monetization of its YouTube platform during the holidays was likely very, very strong, explained Cramer, who also manages the Action Alerts PLUS charitable trust portfolio.

"We have to get our arms around it," the idea that these companies will sport trillion-dollar valuations, Cramer said. "It's a different era," he concluded, and investors better learn to adapt if they haven't already.

Amazon, Netflix, Alphabet and Microsoft all hit new all-time highs in Tuesday's session. With a small tap, Facebook could push FANG+M to new all-time high territory Tuesday. Collectively, FANG commands a market cap of $2.12 trillion. On its own, Apple (AAPL) - Get Report has a $917 billion market cap, pushing the Apple + FANG total north of $3 trillion. 

Update: Starting at 2:36 pm ET, Facebook stock went on a strong run, ultimately closing higher by 2.15% on the day at $189.35. It pushed the stock to new all-time highs for the day, meaning all the FANG stocks hit new all-time highs Tuesday.
