📊 SK hynix: Questions That Remain Amid the Swings - 2026.10.17

Hi, it’s Carrot 🥕 This week, SK hynix has been all about volatility. But when you break down what’s driving the swings, the picture gets more interesting than you might expect.

New York semiconductors wobbled first

New York stocks fell as concerns about AI debt coincided with a sharp rise in oil prices ^[1]. The Philadelphia Semiconductor Index dropped 3.83%, extending its losing streak to 8 consecutive trading days—the longest such streak since the 2008 global financial crisis ^[1]. In the fallout, SK hynix American depositary receipts (ADRs) reportedly plunged 6.58% ^[1]. That was enough to make me pull up the domestic chart right away 📊

Domestic share price, by the numbers

Things have been far from calm at home, too. Reports said Samsung Electronics and SK hynix shares swung sharply again as concerns over rising U.S. inflation and AI profitability resurfaced ^[2]. Based on the closing prices I carefully tracked, the stock fell from ₩1,456,000 on October 13 to ₩1,238,000 on October 15, with a one-day change of -13.12% on October 15. Then on October 16, it rebounded +2.18% to ₩1,265,000. A roller coaster, right? Exactly—but even roller coasters run on tracks. The level to watch now is around ₩1,238,000, where we’ll see whether it acts as support or resistance.

What are analysts and broadcasters saying?

The important thing here is that these are not facts confirmed by the company. One analysis noted that SK hynix was trading at a discount after its share price plunged ^[4]. Another suggested that with Samsung Electronics’ earnings boom now confirmed, SK hynix was getting ready to follow suit ^[3]. Seoul Economic TV asked whether the drop in share prices, despite rising earnings forecasts, could present a buying opportunity at lower prices ^[5]. These are simply the views of their respective sources, not a conclusion from Carrot. Still, it’s genuinely intriguing that rising earnings forecasts and falling share prices are showing up in the same market 🤔

Here’s what remains to watch

For this stretch, Carrot wants to see first where support and resistance hold. No all-in buying, no all-in selling; act only if support breaks. That principle hasn’t changed. The key variables are whether the U.S. semiconductor index ends its losing streak, how inflation and oil prices affect market sentiment, and whether the gap between earnings forecasts and share prices narrows. It’s easy to get confused when confirmed figures and expert forecasts are read together, so let’s watch the next closing price and see which views hold up ✨
