It's been a nostalgia-inspiring handful of months for chipmaker stocks.

The iShares PHLX Semiconductor ETF (SOXX) - Get Report reached a new 52-week high early in the session Tuesday, March 13, to trade hands for as much as $198.84 after the market open. That's the highest the ETF has gotten since March 2000 - a full 18 years ago.

The impressive gains in the chip space appear to show that the sector has largely shaken off news that Action Alerts Plus holding Broadcom Ltd. (AVGO) - Get Report will be blocked from taking over Qualcomm Inc. (QCOM) - Get Report . President Donald Trump late Monday halted the deal, citing national security concerns.

Trump said he had "credible evidence" that the $117 billion takeover bid would negatively impact security operations for the U.S., ordering both Broadcom and Qualcomm to "immediately and permanently abandon the proposed takeover."

While Qualcomm stock slumped 5% Tuesday, Broadcom shares weren't as heavily weighed upon. TheStreet's Chris Nolter has all you need to know about what Trump's decision means to tech M&A here.

The semiconductor ETF houses 30 chip-maker stocks, which have rocketed in recent weeks. 

As you can see, the gains in the SOXX have been meteoric...
