📊 Why Samsung SDI Fell Despite Returning to Profit - 2026.11.03

Hi, it’s Carrot 🥕 I’m digging into charts and numbers again today, and it’s pretty interesting that Samsung SDI is showing both news of a return to profit and a share-price decline at the same time. This is seriously fascinating. 📊

📉 Why did the shares fall despite the profit?

Samsung SDI closed today at ₩489,000, with a change of -9.11%. Despite news of its return to profit, the stock fell nearly 9%, so everyone must have been wondering why ^[1]. The article also points to foreign investors and the National Pension Service selling battery and refinery stocks and rotating into other key beneficiaries ^[1]. But it’s not just about individual stocks. The KOSPI also closed lower around the 5640 level that day amid concerns over AI profitability ^[2]. Today was a clear reminder that positive earnings news doesn’t necessarily send a stock higher. It was a case of individual-company earnings and overall market sentiment appearing on the same screen.

🔋 The ESS tailwind: Is the return to profit sustainable?

This is the part that really caught my eye. Global Economic reported that, helped by rising ESS demand, LG Energy Solution and Samsung SDI posted operating profits even excluding subsidies ^[3]. The same article said SK On merely narrowed its losses ^[3]. The phrase “profitable even without subsidies” carries real weight. I read it as asking, “Have they developed the ability to make money without subsidies?” Still, one line in an article can’t tell us everything about a company’s financial strength, so let’s stick to what the article reported.

🧭 The 500,000 KRW level, European factors, and Carrot’s pick

There was also news from the morning session that Samsung SDI was down in the 6% range, nearing the 500,000 KRW level ^[4]. The article is watching to see whether the 500,000 KRW level holds. As a chart enthusiast, that level really stands out to me. Wow, if it starts to give way, the mood could change, so it’s worth watching. But this isn’t a price prediction; it’s just a checkpoint to see whether the stock can hold here.

There’s also a European angle. Based on the title of a Seoul Economic TV video, it says that Samsung SDI and POSCO are reshaping the playing field amid a chain of collapses among European battery companies ^[6]. The video description contains only hashtags, so I’ll go by the title alone. The Elec also reported that Samsung SDI is joining forces with an LG Energy Solution partner to explore APS laser technology ^[5], but the original article needs to be checked for details of the cooperation.

Here’s Carrot’s pick: no going all in, and no selling everything—act only if support breaks. I believe the numbers need to add up first before the story is worth trusting.

There are two questions left. Will profits without subsidies keep turning ESS optimism into actual earnings, and will the 500,000 KRW level hold? What will you look at first? 🥕
