• Apple Inc. loses over $100 billion in market value at open following Trump's tariff threat.
  • Shares drop as much as 4% pre-market, dragging major indices lower.
  • Analysts warn of potential supply chain disruptions and consumer price hikes if tariffs are enacted.

Market Reacts to Trade Policy Shock

Apple Inc. saw more than $100 billion wiped from its market capitalization at Thursday's open after former President Donald Trump floated a 25% tariff on iPhones manufactured outside the U.S. The tech giant's shares tumbled as much as 4% in pre-market trading, with the broader market following suit as the S&P 500 and Nasdaq Composite opened lower.

"This is exactly the kind of policy risk that keeps tech investors awake at night," said a portfolio manager at a major hedge fund who asked not to be named. "Apple's entire supply chain is built around global manufacturing - you can't unwind that overnight."

The China Factor

The proposed tariffs would hit Apple particularly hard given its heavy reliance on Chinese manufacturing. While the company has been gradually diversifying production to India and Vietnam, analysts estimate over 90% of iPhones are still assembled in China.

"Without a deal, Apple would be forced to either absorb these costs or pass them along to consumers," noted Bernstein analyst Toni Sacconaghi in a flash note to clients. "Neither scenario is particularly appealing to shareholders."

Attempts to reach Apple for comment were unsuccessful, though sources familiar with the matter say executives have been in emergency meetings since the news broke. The company successfully lobbied for tariff exemptions during Trump's first term, and is expected to mount similar efforts this time around.

Ripple Effects

The selloff extended beyond Apple, with the Philadelphia Semiconductor Index dropping 1.8% and suppliers like Taiwan Semiconductor Manufacturing Co. falling in overseas trading. Bond markets also showed stress, with the 10-year Treasury yield climbing to 4.63% as investors weighed the potential inflationary impact of new tariffs.

Market technicians are watching key support levels for Apple shares, with the $170 mark seen as critical. "If that breaks, we could see another leg down," warned BTIG technical analyst Jonathan Krinsky. "But these policy-driven moves often reverse quickly once cooler heads prevail."
