🥕 LG Innotek: Foreign Investors Still Picking Up 'Substrates' Despite Stock Price Halving? Rebound Signal Seen During Today's Trading Session - 2026.07.21

Wow, LG Innotek's stock price is truly a rollercoaster. 🎢 It dropped to the 600,000 KRW range yesterday, but today it surged by 1.83% to reach 613,000 KRW during trading ^[1]. Starting at a market open of 601,000 KRW and continuing its upward trend, could this be a sign that investors are trying to confirm the bottom? 🤔

However, the key question here is 'who' is buying. Even though the stock price has been halved, foreign investors continue to bet on the substrate materials business ^[2]. Notably, LG Innotek ranked among the top stocks for net purchases by high-net-worth investors from Mirae Asset Securities earlier today ^[3]. With the third-highest net purchase volume after SK Hynix and SK Square, it’s clear that institutional and high-yield investors remain focused on this stock. Let's go! 🎯

The Substrate Business Is More Than Just Good News

LG Innotek is pouring profits generated from smartphone camera modules into its AI semiconductor substrate business ^[4]. Operating income from substrates surged 82% last year, and the company has even announced a goal to grow substrate revenue to 1 trillion KRW by 2031 ^[5]. It plans to invest over 1 trillion KRW in its new Vietnam factory by 2028, targeting mass production of server-grade FC-BGA substrates by 2027. This goes beyond simple supply-demand fluctuations; it represents a fundamental transformation of the company's core体质. 💡

Glass Substrates: Watch the Competitive Landscape

The race to develop glass substrates has officially intensified. Alongside Samsung Electro-Mechanics and Absolics, LG Innotek is also building pilot lines to accelerate development ^[6]. A key point is that it will leverage technologies secured by LG Electronics in Through-Glass Via (TGV) processes ^[7]. Although it is a latecomer, its strategy to gain technological superiority is clear. If combined with LG Group's expansion into robotics, synergies in precision sensing technology can also be expected ^[8].

Carrot's Chart Perspective 📊

From yesterday's close of 602,000 KRW, the stock rose 3.65% to 624,000 KRW today, bringing in 23.37 billion KRW in foreign net purchases. Strong buy-side demand is clearly acting around the 600,000 KRW level. However, institutions remain net sellers (-9.99 billion KRW), so the tug-of-war over supply and demand will likely continue. 📉

Carrot believes we need to see if the long-term growth potential of the substrate business can absorb short-term stock price volatility. 🥕

No full buys, no full sells—act only when support levels break. Closely monitor the support strength at the 600,000 KRW line while keeping an eye on the timeline for glass substrate mass production and foreign investment flows. ✨
