SKC stock Lately, among friends who are into investing, talk about SKC has been quite frequent. And sure enough, today (April 16, 2026), SKC’s stock price surged by over 10%, truly capturing the market’s attention. You all heard the news, right? It even triggered a VI (Volatility Interruption) after rising over 20% at one point during the trading day. The truth is, SKC had been going through a pretty tough time for a while due to poor performance and a declining stock price. So, it’s inevitable that this surge is drawing even more interest. Is this truly a signal of SKC’s rebound, or just a temporary phenomenon?
To be honest, the backdrop to this stock price increase is likely heavily influenced by the high expectations for SKC’s make-or-break semiconductor glass substrate business. Let’s thoroughly examine whether this new business, which even SK Group Chairman Chey Tae-won is personally overseeing, can heal SKC’s ‘sore spot’ and create new growth engines.
SKC, The Background of the Sudden Stock Price Surge

Today, SKC’s stock price was absolutely red-hot. It closed at 110,300 won, up 10.52% from the previous trading day, and even triggered a VI during intraday trading with a rise of over 20%. Such a sudden surge is clear evidence that special market attention was focused on it. However, there was no special disclosure about SKC today. This situation only adds to the curiosity.
- Reflection of Market Expectations: Long-term growth expectations for semiconductor materials, especially the glass substrate business, seem to have been pre-reflected in the stock price.
- Institutional and Foreign Buying: Recent supply and demand changes are noteworthy, with foreigners net buying over 130,000 shares and institutions net selling.
- Concurrent Rise in Related Themes: SKC is linked to various advanced material themes such as secondary battery materials and glass substrates, so the strength of related sectors may have had an impact.
Is the Semiconductor Glass Substrate the Key to SKC’s Future?

In recent years, SKC has suffered from a ‘triple whammy’ of performance, stock price, and financial health. In particular, the prolonged ‘EV chasm’ (temporary slowdown in demand) led to difficulties in the battery material business, even forcing them to abandon the cathode material business. In this situation, SKC’s breakthrough has been high-performance computing semiconductor glass substrates. Through its subsidiary Absolics, it is staking its future on the world’s first mass production of glass substrates, and Chairman Chey Tae-won reportedly visited the US factory in person, showing deep interest.
- High Technical Difficulty: Glass substrates are much thinner and flatter than existing plastic substrates, and enable the implementation of fine circuits, making them essential technology for high-performance semiconductors.
- Absolics’ Role: Established by SKC in 2021, Absolics is the core hub of the glass substrate business. In July 2024, Chairman Chey Tae-won personally introduced its technological competitiveness and engaged in sales activities.
- Future Market Preemption: Although still in its early stages, the potential of the glass substrate market is enormous as demand for high-performance semiconductors like artificial intelligence (AI) is exploding.
1 Trillion Won Rights Offering, Will It Seize Opportunity Amidst Crisis?

SKC is pursuing a 1 trillion won rights offering to invest in new businesses and improve its financial structure. In fact, there were concerns that the actual amount raised could decrease if the stock price fell, but today’s stock surge will positively impact the success of the rights offering. The funds secured through this rights offering will be used to maintain investment in Absolics and repay borrowings. Successful fundraising is bound to be an important stepping stone for SKC’s future.
- Securing Growth Engines: The strategy is to secure long-term growth engines by investing in new businesses like glass substrates with the rights offering funds.
- Strengthening Financial Stability: It is also expected to lower the debt ratio and improve financial soundness by repaying borrowings.
- Restoring Market Trust: A successful rights offering can serve as an opportunity to restore market trust by demonstrating SKC’s commitment to new business initiatives and efforts to improve its financial situation to investors.
SKC’s recent stock surge seems to be a clear signal of the market’s fervent expectations for a new growth engine: semiconductor glass substrates. Of course, there are still many hurdles to overcome, but I hope SKC uses this opportunity to firmly establish itself as an advanced materials company. I’m really curious to see what moves SKC will make next.
