1 Trillion Won Vanishes in a Day: Why the Electric Vehicle Parts Leader Was Hit Again

On January 13, shares of Aptiv PLC (NYSE: APTV) plunged 6.02% to close at $82.93 on the New York Stock Exchange. The company’s market capitalization evaporated by approximately $1.017 billion—roughly 1.3 trillion Korean won—in a single day. Trading volume exceeded 2.34 million shares, reflecting a pronounced sell-off by investors.

Since announcing a corporate restructuring plan to spin off its Electrical Distribution Systems (EDS) division into a separately listed company in January 2025, Aptiv’s stock has become more volatile amid slowing electric-vehicle demand and downward revisions to its earnings outlook. Earlier, the company lowered its 2024 sales guidance and outlined additional cost-reduction measures to boost profitability.

In 2024, Aptiv continued its restructuring efforts—cutting hundreds of jobs at facilities such as its Krakow, Poland, plant—as it pivots toward businesses centered on electric and autonomous vehicles.

Headquartered in Dublin, Ireland, Aptiv is a global automotive-electronics supplier that provides components and advanced driver-assistance system (ADAS) software to major automakers, including the Detroit Three, Volkswagen, and BMW. After carving out its powertrain business from Delphi in 2017 to focus on electronics and software, Aptiv has been viewed as a “hidden beneficiary” of the electric and autonomous vehicle era.
