It's been a rough week for the FAANG stocks. The group has proven that, just as a rising tide lifts all ships, so too can a big fat Facebook Inc. (FB) - Get Report hurricane sink them.

FANG, an acronym coined by TheStreet's founder Jim Cramer that stands for Facebook, Amazon.com Inc. (AMZN) - Get Report , Apple (AAPL) - Get Report , Netflix Inc. (NFLX) - Get Report and Alphabet Inc. (GOOGL) - Get Report , has typically been regarded as the best and brightest spot in an already-on-fire tech sector. But that sentiment has shifted significantly in the past two weeks as the fallout from Facebook's Cambridge Analytica scandal has infected all of tech like a nasty virus.

These hard times are most certainly not here to stay for these tech rainmakers. If you've always wanted to invest in the sector but couldn't quite justify sky-high valuations, now may be the time to act.

Consider Facebook's stock, which has tanked about 11% over the last month. Shares traded as low as $152.22 this week. The last time the stock was that cheap was July 7, 2017. Despite the prospect for regulation (which could take years to happen) and near-term PR hurdles, Facebook's business model is still a cash cow. That cash could be plowed into acquisitions or to enact a dividend that jump-starts investor confidence. Facebook still has a commanding lead in the social media space, let's not forget.

"Zuckerberg standing before Congress will inhibit downside, and Facebook still has the opportunity to hire outside counsel to help rebuild investor and consumer confidence," points out Jim Cramer's Action Alerts Plus research team. Facebook is a long-time Action Alerts Plus holding.

Or how about the other FAaNG names. Apple's stock has fallen 5% in the last month. But, Apple continues to be a beast of a company, developing products that are integral to our daily lives. It also has an immense cash hoard that could materially boost the stock's total return soon.

Amazon pretty much doesn't need to be pitched to investors. The Action Alerts Plus holding, who stock has tumbled 5% over the past month, is simply crushing rivals in the retail space. It's also becoming a major force in content streaming and the cloud. Netflix has lost 6% in the past month. Like Facebook and Amazon, Netflix is the king in its space. Why not hitch your wagon to that story.

Google is how people search for stuff on the internet and store files. Hard to believe it's stock is worth 6% less than four weeks ago.

Timing the bottom will be tough given all the negative sentiment in the market. A changing in the macroeconomic backdrop isn't helping tech right now, either.

"[With FANG stocks] you are looking at the specter of regulation based on what's going on with some of these privacy issues, but fundamentally those stocks do well in the environment we are exiting, which is low interest rates and low growth," Stifel Financial's chairman and CEO Ron Kruszewski told TheStreet's Executive Editor Brian Sozzi.

Let's not forget the correction the tech sector endured two years ago, as TheStreet's Eric Johnsa points out. In December 2015, the Nasdaq reached as high as 5,156 at its peak before tumbling as low as 4,337 by Feb. 12, 2016, a nasty 16% correction.

But from Feb. 12 through the end of 2016, the Nasdaq climbed higher more than 24% as the sector continued to drive big innovation and promising outlooks. If a rebound like that could happen two years ago, it can happen now -- especially since the Nasdaq has already handed over about 8% of its gains from its most recent high this year.

BlackBerry (BB) - Get Report CEO John Chen, a veteran executive in the tech sector, told Sozzi that the tech stock rout is likely to prove fleeting. "Given the fact the market has been in a bull market for so long, and the high-fliers have seen a really big return, I think what we are seeing is a quick knee-jerk reaction of to many things going on."

"Tech [stocks] will come back," Chen noted, "because technology does represent high value and a lot of good things on in the future in robotics and analytics."

So if you fail to recognize that tech stocks will probably get more expensive in the coming years, not less, you're one of the dumbest on Wall Street. Get ready to go all in.
