Today’s bottom line

Maintain existing holdings in Samsung Electronics and SK hynix. Do not add at current prices. However, this does not mean you should hold positions that you cannot afford to see fall further because of margin debt, collateral requirements, or living expenses. In that case, don’t wait for a rebound; reduce your risk exposure as needed.

The question in the October 21 market-close report was, “After a big rebound, can we trust that the recovery will continue?” The U.S. market gave only a partial answer overnight. AI revenue expectations lifted tech stocks during the regular session, but after hours, semiconductor equipment maker Lam Research’s stock plunged. The fact that AI investment is continuing is not the same as saying that the stocks must rise today.

Goguma’s base case for the rest of today’s session is an attempt to recover from early weakness, with rebounds and pullbacks alternating until gains broaden across the market. The recovery observed after the open is not counted as a forecasting success. There is also insufficient evidence to confirm either a strong uptrend or a complete failure of yesterday’s rebound.

NXT prices at the same time were also 222,500원·1,280,000원, respectively. Parentheses show the distance from the current price to each observation level, not expected returns. The observation levels remain unchanged from those given yesterday. Samsung Electronics’ 224,750원 is a calculated reference level, not an actual order price based on the trading tick size.

The first move is to hold. Reclaiming the strengthening observation level supports the hold case, but is not an automatic buy signal. Falling below the weakening level warns that the rebound is failing, but does not by itself mean the industry is collapsing or that you should sell everything. If the business, valuation, or risk limits have deteriorated, reduce your position without waiting for prices to recover.

Why did the U.S. market rise, then wobble again?

The regular-session rally was driven not by rate-cut expectations but by expectations for AI companies’ revenue. SpaceX and Supermicro’s announcements after the previous day’s close supported sentiment toward tech stocks, with the Nasdaq closing up +1.05% and the Philadelphia Semiconductor Index up +1.97%. The S&P 500 gained +0.58%. However, U.S. trading volume was 16.11 billion shares, below the recent 20-day average of 17.10 billion. The Nasdaq had 216 new lows, more than its 53 new highs. This is a different indicator from the number of advancing and declining stocks that day. The index rebound was clear, but there was little evidence that the market as a whole had become healthier.

The interest-rate environment remains a headwind. The U.S. 10-year yield was around 5.1% intraday, and Brent crude settled at $108.82 per barrel. The cost used to discount future earnings to their present value remains high. Good AI news does not resolve the discount-rate problem facing risk assets. We did not use improving credit conditions as a cause of this rebound because we could not obtain the latest confirmed credit spread data. AP market wrap

Meta’s increased investment is good news for suppliers—and a test of returns

Meta’s third-quarter revenue was $64.601 billion, up 26% year over year. However, capital expenditures of $34.91 billion, including finance lease principal, exceeded operating cash flow of $32.79 billion, leaving free cash flow at −$2.12 billion. Operating income calculated excluding legal expenses alone rose 11.42% year over year, but the operating margin fell from 40.08% to 35.42%. This calculation does not represent normalized earnings with all one-time factors removed. The full-year capital expenditure outlook is $135 billion–$145 billion. The company’s willingness to invest is favorable for semiconductor suppliers, but orders can only be sustained if end customers generate sufficient cash returns. Meta official third-quarter results

Tesla’s revenue of $28.046 billion was flat year over year, while operating income fell 56%. Its share price also reversed from an initial after-hours gain to a decline. This cannot be generalized into a failure of the entire AI industry. Rather, even within the same group of tech stocks, it is reasonable to interpret the market as becoming more demanding about near-term earnings and cash generation than investment potential. We have not reviewed the full earnings Q&A, so we do not identify any single remark as the definitive cause of the sharp decline. Tesla official third-quarter materials

Memory demand remains. Earnings durability is a separate question

It would be getting the sequence backward to conclude that memory orders have collapsed simply because Lam’s share price fell. The company’s quarterly revenue was $8.219 billion, up about 22% from the previous quarter, and adjusted earnings per share were $2.20. The midpoint of its next-quarter revenue outlook is $8.6 billion. The amount left after subtracting capital expenditures from operating cash flow was also about $3.240 billion. The figures themselves do not point to a collapse in demand. However, market estimates vary by source, so we do not assert that the company “clearly beat consensus and yet the stock fell.” Lam official results

Lam's share of revenue from China rose from 26% to 35%. A calculation can show that China accounted for a large portion of the quarterly increase. But that figure alone cannot establish that purchases were pulled forward ahead of regulatory changes. We need to consider both the risk that increased equipment spending could signal higher supply next year and the positive sign that customers are investing now.Lam earnings presentation slides

Texas Instruments reported quarterly revenue of $6.06 billion, up 28% year over year. This supports a recovery in industrial and analog markets, but the midpoint of its next-quarter revenue outlook is $6.05 billion, roughly in line with this quarter. An analog recovery cannot be turned directly into evidence of HBM demand or described as accelerating growth.TI official earnings results

There are several steps between order plans and revenue for Korean companies

NVIDIA announced plans to expand production capacity with substrate, packaging, and testing suppliers. Google Cloud also announced plans to commercialize the Vera Rubin-based A5X. These are signs that investment in AI infrastructure is continuing. However, the maximum number of GPUs that could be connected is not the number already sold, and capacity plans do not constitute confirmed HBM revenue allocated to Samsung Electronics or SK hynix. Samsung Electro-Mechanics, mentioned in NVIDIA's announcement, is a different company and business from Samsung Electronics' HBM contracts.NVIDIA supply chain announcement · Google Cloud announcement

The spot memory market is not moving in one direction either. TrendForce's October 21 review pointed to tight DDR5 supply alongside weak DDR4 trading. Some NAND products were also weak. The projected 10–15% increase in fourth-quarter contract prices for general-purpose DRAM and 15–20% for NAND, cited in a separate September 30 forecast, are projections—not average selling prices already realized by individual companies.Strength in HBM and server DRAM does not guarantee profitability across all memory products.

That is why the bar for holding is different from the bar for adding to a position

Samsung Electronics' preliminary third-quarter revenue was KRW 195 trillion, with operating profit of KRW 107.4 trillion. These are strong operating results, but details on the business-unit mix, net income attributable to shareholders, and cash flow after investment are not yet available. SK hynix's second-quarter net income exceeded its operating profit. Annualizing that net income by multiplying it by four could overstate how undervalued the stock is.Samsung Electronics preliminary third-quarter results · SK hynix second-quarter results

The available information is not bad enough to abandon the existing investment thesis. But neither does it establish a conservative per-share value that would justify buying more at the current price. This time, we will not force new Bear, Base, and Bull price targets. The price levels below are reference points for assessing today's recovery, not fair-value targets for the next 3–6 months.

How to act at each price level today

As of 09:21, Samsung Electronics is above its regular-session opening price of 221,500 won, and SK hynix is also above its opening price of 1,273,000 won. However, both remain below the previous close and the rebound strengthening observation levels. SK hynix, in particular, traded at 1,255,000 won on NXT at 8:50 a.m., below the weakening threshold, before recovering.“A potential end to the decline” is now possible, but “a strong recovery has been confirmed” is not. Intraday price source

Scenario	Samsung Electronics / SK hynix levels	Recommended action
Recovery strengthens	Reclaim 224,750 won or higher / 1,316,000 won or higher. A close above these levels would be stronger evidence than a brief intraday trade.	This would strengthen the case for holding existing positions. Do not buy more based solely on a price breakout. Do not keep raising your buy target to chase each new high.
Middle range · current	Samsung: 217,000 won or higher but below 224,750 won. SK hynix: 1,258,000 won or higher but below 1,316,000 won.	Hold existing positions and hold off on adding. Do not repeatedly sell and rebuy solely because of a rebound or pullback.
Rebound weakens	Below 217,000 won / below 1,258,000 won. If the closing price is also below these levels, the risk that yesterday’s rebound has failed increases.	Do not add to the position. If the price alone breaks below the level, do not automatically stop out; immediately reassess the business, valuation, and your ability to tolerate losses. If the reduction conditions below are confirmed, trim without waiting for a recovery.

Do not assess the two stocks as a single position. If only Samsung Electronics recovers its strengthening level, that raises confidence only in holding Samsung Electronics. If SK hynix falls below its weakening level, reassess SK hynix separately. The previous day's highs—Samsung Electronics at 228,000 won (+2.47%) and SK hynix at 1,329,000 won (+3.83%)—are reference prices only, not new mandatory buy levels.

When to actually reduce your position

**First, reduce your position now if your account is exposed to risks you cannot afford.**This applies if you need the money soon, lack sufficient collateral, or have exceeded your personally set maximum loss limit, regardless of the industry's long-term outlook. Since we have not reviewed your entire account, we do not provide a blanket sell percentage or share count.

**Second, reduce your position even above the price threshold if the business or shareholder value is impaired.**Examples include cancellation of a major customer contract or a material price renegotiation; a decline in expected recurring earnings due to deteriorating yields and rising costs; or an investment or financing structure that significantly reduces the cash attributable to existing shareholders. Do not dismiss these changes by saying, “It will recover later.”

When to switch to adding to your position

Check three things: product prices, sales volume, and profitability; recurring earnings attributable to shareholders; and cash flow after investment and financing. **Add to your position if a conservative calculation based on this information still shows sufficient upside at the current price and the funding risk is manageable.**There is no rule to wait at all costs until the official announcement, or to wait several more days after it. Make your decision as soon as the necessary information is available. Conversely, do not justify a purchase by raising your target price just because the stock has risen.

Flows define the breadth of the recovery; earnings define the reason to hold

As of the 09:21 data collection, the KOSPI had 198 advancing stocks and 658 declining stocks, while the KOSDAQ had 384 advancing stocks and 1,228 declining stocks. Foreign net buying in the KOSPI does not mean the entire market has recovered. Large-cap resilience can coexist with weakness in the rest of the market.

Market	Individual net buying	Foreign net buying	Institutional net buying
KOSPI	−₩108.4 billion	+₩167.0 billion	−₩63.3 billion
KOSDAQ	+₩117.3 billion	−₩77.7 billion	−₩29.7 billion

The three investor categories do not sum to zero because other corporations and some categories are excluded. The provider did not specify the execution-time basis for individual flows, so these are not claimed to be synchronized to the second with stock quotes. This table shows cumulative amounts; without an earlier snapshot on the same basis, no change figures have been calculated. KOSPI flows and advances/declines · KOSDAQ flows and advances/declines

Do not compare early-session trading volume with the full-day average and conclude that volume has exploded or that forced liquidation is underway. Samsung Electronics' cumulative volume was 1,882,902 shares on KRX and 2,889,371 on NXT. SK hynix recorded 416,276 and 383,797 shares, respectively. These are cumulative totals from venues with different opening times and are real-time figures that include incomplete intraday bars. Raw trading volume data

What to look for in upcoming events

SK hynix is scheduled to provide a detailed earnings briefing on October 28 at 09:00 KST, and Samsung Electronics on October 29 at 10:00 KST. The U.S. FOMC meeting is scheduled for October 27–28 local time. These events mark when new information becomes available; they are not trading instructions. For SK hynix, check earnings and cash conversion from HBM and mainstream memory, as well as capital allocation related to investment and subsidiaries. For Samsung Electronics, assess how much of its strong preliminary operating profit translates into recurring earnings attributable to shareholders and cash.

Disagreements that remain after the discussion

Onion emphasized the short-term demand boost from AI investment, while Peanut focused on the pace of earnings confirmation and the risk of supply expansion from 2027 onward. Acorn gave more weight to return on investment and cash flow attributable to shareholders, while Carrot focused more on the size of the rebound and risk limits. The Goguma Team adopted neither the optimism that “the next two quarters are safe” nor the leap in logic that “equipment stocks plunged, so Korean memory stocks must be sold too.” It also did not force a ranking of which to add more of now, Samsung Electronics or SK hynix.

**Hold today, but this is no day to stay the course unconditionally.**A recovery to 224,750 won for Samsung and 1,316,000 won for Hynix is positive. A break below 217,000 won for Samsung and 1,258,000 won for Hynix is a warning. Final decisions to buy or trim should be based not only on price, but also on business earnings and cash flow, current valuation, and tolerable risk.
