Yang Guang bit | October 17 $ETH — Rejected at rebound highs and pulled back; favor selling rallies amid surging oil prices
【Today’s Strategy】
Entry: Set up short positions on a rebound to the 2430—2445 range
Stop-loss: Above 2465
Take-profit targets:
First target: 2400—2410
Second target: 2375—2385
【Key Takeaways】
ETH rebounded with the broader market to 2493.48 last night before coming under pressure and pulling back; it is currently trading around 2417. On the 4-hour chart, price is below all moving averages, which are fully bearishly aligned, and the weak structure remains unchanged. On the news front, Trump said he may strike Iranian nuclear facilities, while the US and Israel are reportedly discussing strike plans in secret; Brent crude surged to $110, stoking safe-haven sentiment. Fed Chair Warsh said he would not prejudge the rate decision, and expectations of an October rate hike fell below 15%, but the 10-year Treasury yield climbed back above 5.12%. On-chain, Bitcoin ETFs saw net outflows of more than 3100 BTC on CPI day, as institutional investors remained cautious. Weekend liquidity is thin; the intraday strategy is to favor selling rallies and take light short-term longs at support. Don’t chase one-way moves; stick with the trend throughout. A trend-driven collapse or sharp plunge is not expected. $ETH ‌#比特币短线站上8.2万美元

The core question is whether this represents a healthy correction following a rally driven by artificial intelligence (AI), or the beginning of a deeper repricing process within the storage sector. Rather than buying simply because prices have fallen, it would be more prudent to focus on earnings expectations, memory pricing, and whether each company can maintain its profit margins.
My perspectives on storage sector stocks:
* Micron (MU): Monitor demand for DRAM and HBM, memory growth linked to AI, and gross profit margin forecasts. Strong AI demand could bolster earnings, though these expectations may already be priced into the stock.
* SanDisk (SNDK): Focus on NAND flash pricing, demand for enterprise SSDs, and the sustainability of any earnings recovery. NAND supply and price cycles can make this stock particularly volatile.
* Western Digital (WDC): Evaluate "nearline" (high-capacity/accessible) HDD demand from AI data centers, cloud computing expenditures, and free cash flow. The factors influencing HDD demand differ from those affecting NAND and DRAM.
* Seagate (STX): As data center storage requirements grow, keep an eye on demand for high-capacity drives, pricing power, and profit margins.
* Track NAND market conditions, enterprise SSD adoption rates, and the company's valuation relative to earnings expectations.
What signs might justify rebuilding a position? I would look at the following three points:
* Stabilization of fundamental indicators: A halt in the deterioration of memory and NAND prices, company forecasts, and earnings estimates.
* Confirmation through price action: Stocks forming higher lows and reclaiming key moving averages, accompanied by stronger trading volume.
* Attractive valuation: Expected earnings growth that justifies the current price, even under less optimistic scenarios.
A decline in a stock price is not, by itself, a buy signal. If earnings estimates are falling faster than the stock price, the valuation may not have actually become cheaper.
Rather than buying the entire storage sector indiscriminately, I prefer to differentiate between individual companies. While AI demand serves as a long-term tailwind, memory, NAND flash, and hard disk drives each have their own unique supply cycles, competitive pressures, and profit margins.
An important distinction: A pullback driven by profit-taking is fundamentally different from one caused by weak forward guidance or falling memory prices. The latter scenario warrants a much more cautious approach. Which of these stocks—MU, SNDK, WDC, or STX—are you following most closely? I can help you compare their valuations, earnings outlooks, technical levels, and the potential factors that could support a recovery.

KOSPI +3.3%: A relief bounce or the start of a recovery?
My initial assessment: This appears to be a potential relief rally; however, a single strong session is not enough to confirm a broader recovery. The key question is whether semiconductor stocks can sustain this rebound following the sharp sell-off, or if the gains are merely driven by short covering and bargain hunting.
The gains seen in Samsung Electronics (+3.6%) and SK Hynix (+3.4%) are particularly significant, as the South Korean market is highly sensitive to semiconductor sentiment and the global AI-memory trade.
What is driving the recovery?
1. The sell-off may have overshot the fundamentals
On October 15, the KOSPI fell by 7.57%, closing at a six-month low following seven consecutive days of losses. During this sell-off, Samsung and SK Hynix lost 23.9% and 31.5% of their value, respectively—creating an opening for bargain hunters to return.
2. Memory chip fundamentals remain supportive
Analysts continue to highlight tight memory supply, robust demand related to artificial intelligence, and expectations for rising DRAM prices. This supports the view that the sell-off was driven more by sentiment and positioning than by a collapse in earnings expectations.
3. Global risk appetite has improved
A recovery in U.S. equities, combined with easing concerns regarding AI-related credit risks, has helped fuel a rebound in Asian technology stocks. However, concerns regarding returns on investment in artificial intelligence, financing costs, and interest rates have not dissipated.
A relief rally or a sustainable recovery?
Bullish scenario — a lasting recovery
* The KOSPI remains above its recent low.
* Samsung and SK Hynix continue their recovery.
* Foreign investors return as net buyers.
* Earnings forecasts and expectations for memory chip prices remain robust.
Bearish scenario — a short-lived rebound
* The index rises toward a resistance level and then reverses.
* Foreign investors continue to sell Korean stocks.
* U.S. bond yields rise, or renewed concerns regarding AI valuations weigh on chip stocks.
* Samsung and SK Hynix fall back below their recovery levels.
What should investors watch for next?
The most critical indicator is not the magnitude of the initial rebound, but whether buying pressure is sustained.
Indicator Bullish interpretation
Foreign investor flows Consistent net buying
Samsung and SK Hynix Gains sustained over several sessions
Memory chip pricing Continued strength in DRAM and HBM
U.S. Treasury yields Stabilization or decline
Earnings expectations Maintenance of upward revisions
A key distinction: On October 16, the KOSPI recorded an intraday gain of up to 3.17%, but closed the day up 2.05% at 5,668.05. Consequently, the sharp intraday rally made the final gain at the close appear more significant than it actually was.
My View
Short-term: Cautiously optimistic
A recovery is possible.
Oversold conditions and attractive entry points could support further gains, though volatility is likely to remain high.
Medium-term: Conditional
Not yet confirmed.
A more substantial recovery would require the stabilization of foreign investor inflows, supportive earnings data, and a more durable improvement in sentiment toward the global technology market.
In summary: I view the 3.3% move not as proof that the downtrend has ended, but as a promising first step. Earnings expectations for the semiconductor sector provide a firmer foundation for this recovery—moving it beyond a mere technical rebound—but the market must demonstrate that buyers are willing to hold their positions, even amidst renewed volatility.
A key factor to watch in the near term will be the earnings outlooks from SK Hynix and Samsung Electronics, set to be released on October 28 and October 29, respectively. These reports could prove decisive in determining whether the recent sell-off was an overreaction or if it reflects a more fundamental reassessment of the AI-driven memory market.
