SK Hynix Technical Deep Dive: Key Support Levels and Recovery Path After AI Memory Leader's Plunge

Overview

Two months ago, SK Hynix was the most valuable company on the Korean stock market. Today, its share price has fallen about 45% from its all-time high. On Aug. 25, the company's production workers' union rejected a previously agreed wage deal by a margin of 25 votes. The stock initially plunged during the session before paring losses, closing down about 1.5% at 1.646 million won, while the KOSPI rose 0.2%.

Placing this level on a longer timeline paints a completely different picture. Data from TradingView shows that 000660 hit an all-time high of 2.987 million won on June 25, with a 52-week low of 253,000 won. In other words, the stock rose more than tenfold within a year, then gave back a substantial portion of those gains. The current price sits almost exactly at the halfway point of that rally—a technically significant level.

For high-beta assets, a pullback itself is not a signal; where the pullback stops is. That is why, ahead of Nvidia's earnings on Aug. 26, the more useful analysis is not to predict direction but to map out key price levels and what they represent.

Key Takeaways

From a price structure perspective, the intraday low on Aug. 25 was 1.557 million won, the close was 1.646 million won, and the previous session's close was 1.671 million won. The sharp intraday drop followed by a recovery of most losses formed a long lower shadow—a bullish reversal candlestick pattern that requires confirmation in subsequent sessions.

In terms of retracement levels, using the 52-week range of 253,000 won to 2.987 million won, the 50% retracement sits at approximately 1.620 million won, the 38.2% retracement at approximately 1.943 million won, and the 61.8% retracement at approximately 1.297 million won. The current price is almost exactly above the 50% retracement—the most important technical reference in this correction.

From the sell-side consensus, all of the roughly 38 to 39 analysts covering the stock have buy-equivalent ratings, with none issuing a sell. The 12-month average target price is about 3.16 million won, with a high estimate of 5.30 million won and a low of 1.20 million won. The more than fourfold spread between the highest and lowest targets reflects extreme disagreement about the memory cycle.

On corporate actions, on Aug. 19 the company announced a 40 trillion won share buyback program, one of the most important fundamental variables in this pullback.

From Korea's Most Valuable Company to a 40% Drawdown

A Historic Moment in June

To understand the nature of this pullback, one must first grasp the extremity of the preceding rally. According to KED Global, on June 22 SK Hynix closed up 5.6% at 2.919 million won, with an intraday high of 2.945 million won, surpassing Samsung Electronics in market capitalization for the first time to become Korea's largest listed company—the first change at the top in over 25 years. That day marked the stock's eighth consecutive session of gains.

Three days later, the stock hit its all-time high of 2.987 million won. TradingView's market description notes that by mid-2026, SK Hynix accounted for more than half of the total market capitalization of the Korea Exchange. When a single stock carries such weight in a country's main index, the index itself becomes a proxy for that stock, and any pullback in the stock is amplified by the market-wide capital structure.

Nature and Magnitude of the Pullback

From 2.987 million won to 1.646 million won, the decline is about 45%. For an ordinary stock, that would be considered a bear market, but for a stock that rose more than tenfold in 52 weeks, it is closer to a normal correction of a parabolic move. TradingView records the stock's volatility at about 3.31% and beta at about 1.77—a typical high-beta name.

It should be noted that the pullback was not caused by a single negative factor. AI-related valuations have undergone several rounds of adjustment globally, Asian semiconductor stocks generally saw pre-earnings de-risking ahead of Nvidia's report, and the wage negotiation is only the latest variable. Attributing the entire 45% decline to labor issues would seriously misjudge the driving structure of this correction.

What the Rejected Wage Deal Means

The Real Divide Behind the 25-Vote Margin

The vote itself deserves a closer look. According to Korean media reports, 50.08% of the production workers' union, or 7,535 votes, opposed the deal, while 49.92%, or 7,510 votes, supported it—a margin of just 25 votes, with a turnout of 93.81%. The technical and office workers' union, which voted the same day, approved the same deal with about 60% in favor. The two unions negotiate separately with management, and the results apply to each respectively.

The content of the rejected deal is key. The package included a 6.3% wage increase and a structural change: converting 60% of profit-sharing bonuses into company stock, leaving only 40% in cash. It also raised the housing loan limit for married employees from 100 million won to 200 million won, and included a reference price protection mechanism for stock payments, using the lowest closing price among the earnings announcement date, cash payment date, and stock payment date as the pricing basis.

The real point of contention is not the wage increase but the form of payment. According to TradingKey's analysis, the company had previously committed to allocating 10% of annual operating profit to employee bonuses. Based on earlier estimates, the per-capita bonus for 2026 could reach a substantial level. When the bonus pool becomes that large, tying 60% of it to the stock price effectively forces employees to bear both income risk and market risk. With the stock having just fallen 40% from its peak, employees' resistance to this arrangement is entirely understandable.

Actual Impact on Production and Valuation

From a factual standpoint, the rejection does not currently constitute a production disruption. The vote simply means negotiations return to the table. Investing.com's report also explicitly notes that the narrow margin itself does not indicate an immediate impact on production.

But from a valuation perspective, it introduces two new variables. First, uncertainty on the cost side: a renegotiated deal will likely require a higher cash ratio or a larger overall package, which will affect the expense structure in coming quarters. Second, and more easily overlooked, the vote revealed that views on the stock price within the company are not uniform. When half of the employees who know the company's operations best are unwilling to accept stock payments, that signal is worth noting for outside investors, even though it does not constitute a judgment on fundamentals.

One must refrain from equating employees' risk preferences with their outlook on the company's prospects. Employees bear concentration risk in their personal income, not a portfolio allocation, and the decision logic is completely different.

Key Price Levels and Volatility Structure

Support Levels Below

The nearest support is 1.557 million won, the intraday low on Aug. 25. This level saw clear absorption that day, with the price recovering to close at 1.646 million won. Whether the intraday low is broken in subsequent sessions is the first condition for validating the long lower shadow.

The second layer is the 50% retracement of the 52-week range, at approximately 1.620 million won. The current price sits almost exactly above it, and together with the intraday low it forms a dense support zone about 4% wide. Technically, if such a zone is lost, the price often accelerates downward because the natural buffer of buy orders disappears in a range lacking intermediate trading structure.

The third layer is the round number of 1.5 million won. It has no independent technical significance, but round numbers on high-priced stocks often correspond to clusters of option and structured product strike prices.

A deeper layer is the 61.8% retracement at approximately 1.297 million won, close to the lower end of some sell-side target prices. This level would not be touched in a normal scenario, but it serves as a reference in an extreme correction scenario.

Resistance Levels Above

The first layer is 1.671 million won, the closing price on Aug. 24 and the starting point of the current decline. Reclaiming this level would mean the shock from the wage vote has been fully digested.

The second layer is the recent intraday high area around 1.687 million won.

The third layer is the round number of 2 million won, about 21% above the current level.

The fourth layer is the 38.2% retracement at approximately 1.943 million won, adjacent to the 2 million won mark. Together they form a thick resistance band. This is the true medium-term target of this pullback; only by breaking above it can the downtrend structure be considered broken.

As for the all-time high area between 2.919 million and 2.987 million won, it would require a gain of more than 77% from current levels. Without a new industry cycle catalyst, treating it as a short-term reference is unrealistic.

How High Beta Changes Stop-Loss Logic

For an asset with volatility of about 3.31% and beta of about 1.77, conventional percentage-based stop-losses will frequently fail. The intraday range of over 8% between 1.557 million and 1.687 million won on Aug. 25 shows that any stop set within a 3% to 5% band has a high probability of being triggered on a normal trading day, regardless of whether the judgment is correct.

A more suitable approach for this type of asset is to place stops beyond structural levels rather than fixed percentages, while correspondingly reducing position size. For investors tracking prices across markets, related products offered by platforms such as MEXC allow observation of sentiment changes outside Korean trading hours, but one must be aware of the basis between these products and actual Seoul trading prices.

What Fundamentals Provide for These Technical Levels

Earnings Quality Still Expanding

Technical levels need fundamental support to be durable. According to financial data compiled by CNN, the company's most recent quarter saw total revenue grow 40.82% year-over-year and 47.19% quarter-over-quarter; net income grew 108.11% year-over-year and 126.97% quarter-over-quarter; and EPS grew 103.85% year-over-year. The characteristic of these numbers is that sequential growth exceeds year-over-year growth, indicating acceleration rather than deceleration.

On profitability, the company achieved an operating margin of nearly 76% in the most recent quarter—extremely rare in manufacturing—reflecting the pricing power of high-bandwidth memory under the current supply-demand dynamics. TradingView records EBITDA at approximately 143.58 trillion won, with a margin of about 62.89%.

This explains why the stock still finds buyers after a 45% drawdown: at current earnings levels, the valuation has returned from extreme territory to a range that can be discussed.

The 40 Trillion Won Buyback Is the Most Important Corporate Action in This Pullback

On Aug. 19, the company announced a 40 trillion won share buyback program. Around the same time, BofA Securities issued a buy rating, and Morgan Stanley analysts maintained a bullish stance citing a strengthened shareholder return framework and improved free cash flow prospects.

The significance of the buyback for technicals is that it provides a non-market source of buying. When the company continuously repurchases shares in a specific price range, support levels on the chart are reinforced by actual capital, not just the psychological effect of historical trading. What investors need to track is the actual execution pace of the buyback, not the announced size, because there is usually a significant gap between authorized amounts and actual purchases.

It should also be noted that the rejected wage package would have paid 60% of bonuses in company stock, which would objectively offset the buyback. If the renegotiated deal raises the cash ratio, the company's cash expenditure pressure increases, but dilution pressure on outstanding shares decreases—two opposing effects on the stock price.

External Variables: Nvidia Earnings and the Memory Competitive Landscape

The biggest variable facing SK Hynix next is not on its own calendar. Nvidia will report earnings on Aug. 26, and Asian semiconductor stocks are generally nervous ahead of it. As a major supplier of high-bandwidth memory, SK Hynix's revenue depends directly on shipments of AI accelerators, so Nvidia's next-quarter guidance constitutes an indirect disclosure of SK Hynix's order visibility.

The competitive landscape is the second variable. Samsung Electronics has already launched a next-generation HBM4 product and is seeking to enter the supply chains of major customers. The historical pattern of the memory industry is that supply-side concentration determines the sustainability of profit margins; once a second supplier achieves scale certification, the price center will come under pressure. There is currently no sign that this shift has occurred, but it is a risk exposure that must be built into valuation models.

The third variable is capacity expansion. There are reports that the company is considering building a memory fab in Miyagi Prefecture, Japan, potentially involving tens of trillions of won. If confirmed, such a project would simultaneously change the capital expenditure curve and medium-term supply assumptions. As of now, this information comes from media reports and has not been officially confirmed by the company; investors should not treat it as a fait accompli.

The company's next earnings report is expected on Oct. 27. Until then, the lack of regular disclosure-driven catalysts means the stock will be driven mainly by sector beta, wage negotiation progress, and buyback execution over the next two months.

James Mitchell's Exclusive View

The most informative aspect of this stock right now is not the wage vote, but the fact that the price has stopped almost exactly at the 50% retracement of the 52-week range. From 253,000 won to 2.987 million won and back to 1.646 million won, the market erased half of a year's gains in just over forty trading days. The 50% retracement has the strongest psychological property of all retracement levels because it corresponds to the most intuitive judgment: "half the gains have been given back." Whether the price can hold here says more about whether this upcycle is over than any single news item.

The most common misreading in the market is treating the union vote as evidence of deteriorating fundamentals. The dispute was about the form of bonus payment, not the size of the bonus, let alone the company's operating condition. In fact, being able to allocate 10% of annual operating profit as a bonus pool itself indicates that profitability is at an extremely high level. Employees refusing to tie 60% of their income to the stock price reflects risk aversion to personal income concentration, which is not the same type of problem as a portfolio allocation decision. Confusing the two leads to wrong conclusions.

The second underappreciated detail is the candlestick pattern. On Aug. 25, the intraday low was 1.557 million won and the close was 1.646 million won—a long lower shadow on a day with negative news. Bearish news but a close that recovers most of the losses usually means selling pressure was absorbed at a specific level. Whether the absorber was the company buyback, passive index funds, or active allocation cannot be directly determined from public data, but this level deserves repeated testing in the coming weeks.

From a risk management perspective, I believe three sets of data have higher priority than price. First, the actual execution progress of the 40 trillion won buyback—the gap between authorized size and actual purchases determines how much real money stands behind the chart support. Second, the structure of the renegotiated wage deal—changes in the cash-to-stock ratio will affect both expenses and dilution in opposite directions and need to be modeled separately. Third, the relative performance of SK Hynix versus Samsung Electronics after Nvidia's earnings. If the sector strengthens overall but SK Hynix underperforms, it suggests the market is beginning to price a shift in HBM pricing power from a single supplier to a multi-supplier structure—a more important medium-term signal than any price level.

For cross-asset investors, this case offers a reminder about concentration. When a single stock accounts for more than half of a country's main index, the risk profile of the index fundamentally changes; passive investors in that index effectively hold a high-beta position in a single name. This structure is not uncommon among AI-related assets—the Nasdaq's dependence on a handful of companies and the crypto market's dependence on Bitcoin are essentially the same type of problem. The above is an analytical framework based on public information and public data, and does not constitute a judgment on price direction.

FAQ

Why is SK Hynix's stock price falling?

The recent decline is the result of multiple overlapping factors, not a single event. Global AI-related valuations have undergone several rounds of adjustment, Asian semiconductor stocks generally saw pre-earnings de-risking ahead of Nvidia's Aug. 26 report, and the production workers' union's rejection of the wage deal on Aug. 25 is the latest variable. The stock initially plunged during the session and closed down about 1.5% at 1.646 million won. From the all-time high of 2.987 million won on June 25, the cumulative drawdown is about 45%.

Will the union's rejection of the wage deal affect production?

There is currently no sign of an immediate impact on production. The vote means both sides return to the negotiating table to rework the package. The rejected deal included a 6.3% wage increase and a structure converting 60% of profit-sharing bonuses into company stock with 40% in cash. The dispute centered on the form of payment, not the wage level. Notably, the technical and office workers' union approved the same deal with about 60% in favor; the two unions negotiate separately and the results apply to each respectively.

Where are the key support levels for 000660?

The nearest support is 1.557 million won, the intraday low on Aug. 25, which saw clear absorption that day. Below that is the 50% retracement of the 52-week range of 253,000 won to 2.987 million won, at approximately 1.620 million won, which together with the intraday low forms a dense support zone about 4% wide. Further down is the round number of 1.5 million won, and a deeper reference is the 61.8% retracement at approximately 1.297 million won.

Where are the key resistance levels for 000660?

The first layer is 1.671 million won, the closing price on Aug. 24; reclaiming it would mean the shock from the wage vote has been fully digested. Above that is the recent intraday high around 1.687 million won. The most important medium-term resistance band is between 1.943 million and 2 million won—the former is the 38.2% retracement and the latter is a round number; breaking above this zone would mean the downtrend structure is broken. The all-time high area is between 2.919 million and 2.987 million won, more than 77% above current levels.

What do analysts think of this stock?

The sell-side consensus is extremely bullish but with huge dispersion. All of the roughly 38 to 39 analysts covering the stock have buy-equivalent ratings, with none issuing a sell. The 12-month average target price is about 3.16 million won, implying about 89% theoretical upside from current levels. But the highest target is 5.30 million won and the lowest is only 1.20 million won—a more than fourfold spread. This dispersion indicates that the market completely disagrees on the duration of the memory cycle, and investors should not look only at the average.

Are the company's fundamentals still solid?

Based on the latest disclosures, yes. In the most recent quarter, total revenue grew 40.82% year-over-year and 47.19% quarter-over-quarter; net income grew 108.11% year-over-year and 126.97% quarter-over-quarter; and the operating margin was close to 76%. Sequential growth exceeding year-over-year growth means growth is accelerating. The company also announced a 40 trillion won share buyback program on Aug. 19. It should be noted that the high margin is built on the current supply-demand dynamics of high-bandwidth memory, and changes in the competitive landscape will directly affect this premise.

Will Nvidia's earnings affect SK Hynix?

Yes, and it may be the most important external variable in the short term. SK Hynix's revenue depends directly on the shipment pace of AI accelerators, so Nvidia's next-quarter guidance constitutes an indirect disclosure of SK Hynix's order visibility. Strong guidance would support the demand assumption for high-bandwidth memory and create conditions for the price to test the upper resistance band; weak guidance could simultaneously pressure the entire Asian semiconductor sector, and SK Hynix, with its higher beta, typically has greater downside elasticity than the sector average.
 

What risks should investors watch now?

Three areas. On the competitive landscape, Samsung Electronics has launched a next-generation high-bandwidth memory product; if a second supplier achieves scale certification, the industry price center will come under pressure. On negotiations, if the renegotiated wage deal raises the cash ratio, the company's expenses will rise. On volatility, the stock has volatility of about 3.31% and beta of about 1.77, with intraday swings often exceeding 8%; conventional percentage stop-losses are significantly less effective on this type of asset, and position size matters more than stop placement.
