[Edaily Reporter Shin Ha-yeon ] Stocks related to the “plastic-free” movement are rising in unison. This is interpreted as reflecting expectations of spillover benefits amid growing concerns over an escalation of tensions between the U.S. and Iran, which has led to instability in the supply of naphtha, a raw material for plastics.
According to MP Doctor on the 20th, as of 9:23 a.m. today, JINYOUNG CO., LTD(285800)is trading at 1,420 won—the daily price limit—up 29.92% from the previous trading day.
At the same time, stocks classified as “plastic-free” alternatives—including #SERIM B&G (15.6%), Samryoong(014970)(9.07%), HANKUK PACKAGE CO., LTD.(037230)(5.39%), and ECOPLASTIC CORPORATION(038110)(5.10%)—are all on the rise.
With armed conflict between the U.S. and Iran continuing for the eighth consecutive day, the supply of naphtha—a raw material for plastics—is expected to remain unstable for the time being. This has fueled growing expectations that “plastic-free” related stocks—including companies possessing biodegradable materials and eco-friendly packaging technologies that can replace petroleum-based plastics—will benefit indirectly.
JINYOUNG CO., LTD possesses technology for high-performance plastic materials, while SERIM B&G specializes in manufacturing eco-friendly food packaging containers and biodegradable films. Samryoong and Korea Package are companies that produce carton packs, which are considered alternatives to single-use plastic cups. ECOPLASTIC CORPORATION is expanding the use of eco-friendly materials in automotive interior and exterior components.
Meanwhile, on the 18th (local time), U.S. Central Command announced that two U.S. soldiers were killed and one was missing at a Jordanian air force base following an Iranian attack the previous day. These are the first U.S. military fatalities since the two sides agreed to a ceasefire in April of this year.
As military clashes continue to escalate—with both the U.S. and Iran broadening their targets beyond those related to control of the Strait of Hormuz—some observers suggest this could lead to a de facto full-scale war.
