Candlestick Chart

Weekly Update Aug 31 – Sep 04, 2026: On Friday, September 04, 2026 SK hynix Inc. stock [NASDAQ: SKHY] is trending up by 7.68%! Discover the key drivers behind this movement as well as our expert analysis in the detailed breakdown below.

Technology industry expert:

Analyst sentiment – positive

SK hynix (SKHY) sits near the top tier of global memory suppliers, with KRW 97.1T in revenue and an exceptional ROIC of 73.5%, confirming powerful capital efficiency versus semiconductor peers. The balance sheet is solid: total assets KRW 176T against only KRW 55T in liabilities, equity KRW 120.5T, and long‑term debt of just KRW 14.1T (LT debt/capital ~0.12), giving ample capacity for cyclical swings and capex. Cash and short‑term investments of KRW 35.1T provide strategic flexibility for fabs and buybacks.

Technically, the stock is in a strong uptrend: after a brief dip from 164.72 to 161.05, buyers stepped in aggressively, pushing closes back through 164 and then to 176.14 on expanding volume, signaling institutional demand. Intraday 5‑minute action shows shallow pullbacks being bought, with 164–165 acting as a pivotal demand zone. The actionable level is support at 164: above this, long bias is warranted; a decisive break below 161 would invalidate the near‑term bull case.

More Breaking News

Fundamentally and cyclically, SK hynix is leveraged to a tightening DRAM market and surging AI‑memory demand, with additional upside from Temasek’s expected investment, new Japan fabs, Dalian NAND expansion, and a KRW 40T buyback. Versus broader Technology and Semiconductors benchmarks, SKHY offers superior earnings torque into the upcycle with a stronger balance sheet than many memory peers. I expect continued outperformance, with near‑term support at 164, resistance around 185–190, and a 12‑18 month upside target in the low‑200s.

Quick Financial Overview

SK hynix Inc. sits in the middle of a strong memory upcycle, and the weekly chart reflects that shifting sentiment. The stock pushed from the low $160s to around $176 in recent sessions, with the latest weekly close near the high of the range. That move comes after multiple rallies tied to news of Dalian NAND expansion, the Japan build-out, and a massive buyback plan, which together frame SKHY as a capacity-driven AI memory play.

Intraday, SKHY traded a wide range from the mid-$160s premarket up through the high $170s, then consolidated between $173 and $177 into the close. This intraday action shows steady dip-buying rather than panic selling, a sign that short-term traders are defending pullbacks. The grind higher through the afternoon, followed by a close just under the day’s highs, fits a classic momentum pattern where news-supported bids meet limited profit-taking.

On the fundamental side, SK hynix Inc. posts revenue of roughly $97.1B and total assets around $176.1B, backed by strong equity of about $120.5B. Leverage looks manageable with a leverage ratio of 1.5 and long-term debt near $14.1B, while a high recent ROIC figure suggests effective capital use in this upcycle. The large planned buyback and solid balance sheet give SKHY room to support the stock during downturns, but traders still need to respect the cyclical nature of memory pricing.
