Earnings Cycle

The biggest story for SK Hynix this week is that after reporting record Q2 results, the company approved roughly $38 billion in new capacity investment, while the stock remains in a recovery phase following a sharp pullback from recent highs. The market already recognizes the strength of HBM demand. The real question is whether this expansion will extend the earnings cycle—or plant the seeds for future oversupply.

Policy Support

The South Korean government this week announced a KRW 5 trillion semiconductor fund and another KRW 5 trillion in trade financing, targeting materials, components, equipment and fabless companies, while accelerating power and infrastructure construction for semiconductor clusters such as Yongin.

For SK Hynix, these measures directly reduce the supporting costs of capacity expansion and strengthen the domestic supply chain. Part of this policy tailwind is already priced in. What remains less fully priced is whether simultaneous expansion by the government and industry could eventually increase supply enough to pressure memory prices in 2028–2030.

HBM Execution

SK Hynix reported Q2 revenue of KRW 79.3 trillion and operating profit of KRW 60.5 trillion, both record highs. Revenue rose 257% year over year, while operating profit increased 557%.

HBM, AI-server DRAM and enterprise SSDs were the key profit drivers. HBM4 entered mass production and shipment in the second quarter, while the company has also signed long-term agreements with around 10 major customers.

Of the latest KRW 54.3 trillion investment plan, KRW 35.2 trillion will go toward the Yongin Y2 DRAM fab and KRW 19.1 trillion toward the Cheongju M17 NAND fab. Initial cleanroom operations are scheduled for 2029 and 2028, respectively.

Upstream, SK Hynix depends on semiconductor equipment, materials and advanced packaging. Downstream, it is closely tied to Nvidia and other AI-server customers. Samsung and Micron are accelerating their HBM push, but SK Hynix still holds an advantage in production timing, yields and customer relationships.

Key Levels

SKHY closed at $141.65 on August 11, up 4.7% on the day, but still below the heavy trading zone around $150–$156 seen in early August. The short-term structure remains a rebound following a sharp selloff.

Initial support sits around $133–$135, followed by the psychological $130 level. On the upside, the first resistance zone is $143–$145, followed by $150–$156.

A high-volume breakout above $145 could extend the rebound toward $150 and above. A renewed break below $133 would suggest that selling pressure is returning.

Two-Way Strategy

The primary approach is a two-way trading strategy.

For bulls, consider entries if SKHY stabilizes around $135–$138, or after a confirmed high-volume breakout above $145. For the first setup, a stop can be placed below $132, with an initial target at $145 and a second target at $150–$156.

For bears, watch for a failed rebound around $143–$145. If the stock reverses lower and breaks back below $138, short positions could target $133–$135 first, followed by $130 if support fails.

Given SKHY’s high volatility, swing-trade leverage should preferably remain below 5x. Leverage above 10x is better reserved for tightly managed intraday trades. The current setup is best suited to a 2–5 trading-day horizon. A sustained move above $156 would be needed before treating the rebound as a broader medium-term trend.

Main Risks

There are two major risks: a slowdown in AI capital spending that weakens HBM order and pricing expectations, and faster capacity expansion by Samsung and Micron that changes the supply-demand balance earlier than expected.

The key question is no longer whether HBM demand is strong, but how long today’s elevated profitability can last. From a trading perspective, $135 remains the key dividing line between bulls and bears.

According to reports, industry giants such as Apple, Nvidia, and AMD have collectively increased their orders by 10% to 20%, directly boosting TSMC's 2nm monthly production capacity to 120,000 wafers by the end of the year, which exceeds the previous estimate by more than 20% and brings forward the 2027 target by two years. For the first time in history, five factories will ramp up production simultaneously, and the annual compound growth rate of capacity from 2026 to 2028 will reach as high as 70%.

Goldman Sachs: US stocks are showing a "strong index, weak confidence" pattern; catch-up rally may become the main theme of the next phase

Goldman Sachs stated that the current U.S. stock market is showing an unusual pattern: while index performance is strong, investor confidence remains weak. This suggests that the market still has further upside potential, and stocks that previously lagged behind leading AI stocks may soon experience a catch-up rally.
