Nvidia shares traded near $218.40 on August 29, down -4.20% during intraday U.S. trading. Just two days after reporting record quarterly revenue and surging 8% in a single session, the stock is giving back those gains. The earnings itself was pristine. So why did the stock slide again? The answer lies not in the results, but in separate news that broke in the intervening days. Earnings were record-setting Fiscal 2025 second-quarter revenue, announced August 26, reached $96.2 billion—up 106% year-over-year. Data center revenue more than doubled and drove the bulk of growth across the company. CEO Jensen Huang declared that "AI has reached an inflection point," adding that "compute is now revenue." Third-quarter revenue guidance came in at $108 billion (±2%). Among S&P 500 companies, only nine have ever reported quarterly revenue exceeding $100 billion—Nvidia now stands alone in that bracket. The next day, shares rallied over 8%. That move last...

Marvell Technology (MRVL) shares fell -8.18% on August 28, trading near $221.71. A semiconductor giant shedding more than 8% in a day typically signals a major setback. Yet the earnings report delivered the previous day was the strongest in company history. The contradiction demands explanation. By the numbers, nothing adds up. Let's break down the paradox. What happened at Marvell On August 27, Marvell reported fiscal Q2 2027 results. Revenue climbed 37% year-over-year to $2.7393 billion, a company record. The data center segment, which accounts for 79% of total revenue, surged 46% to $2.17 billion. Guidance also beat expectations. The company raised Q3 revenue guidance to $3.15 billion (±5%) and lifted full-year FY2027 revenue guidance to approximately $12 billion—above consensus forecasts. By conventional metrics, this should have been a bullish catalyst. Instead, the stock moved in the opposite direction. Record earnings, but the market wanted more After-hours...

The KOSPI closed at 6,788.88 on August 28, down 1.79%. It marked the first decline in four trading days. Semiconductors drove the retreat. But what knocked them down is striking. A day earlier in New York, NVIDIA reported earnings and the stock surged. After the U.S. close, Marvell Technology posted results that moved the opposite way. It beat consensus. Yet the stock tanked in after-hours trading. "Beat expectations but stock falls." That paradox framed the entire session. Index opened with a smile, closed in tears The KOSPI opened at 6,846.54, down 65.83 points from the prior close. It rallied to 6,901.78 in morning trade, nearly erasing its opening loss. At that point the tone turned defensive—losses contained. The afternoon flipped the script. The index fell to 6,780.13 and closed at 6,788.88. A 121-point swing in a single session. A roller coaster. The KOSDAQ closed at 838.41, up 0.09%, a tepid gain. Retail investors bought; foreign and institutional inve...

On August 28, 2026, SHD (001770) surged 30.00% intraday, approaching the daily upper limit, and traded near 12,350 won on KOSDAQ. The entire move occurred within a single trading session. The KOSDAQ index rose +0.19% in the same period, while the KOSPI fell -0.95% . The broader market showed modest, mixed movement. SHD's 30% jump was driven by stock-specific factors, not market-wide momentum. Why this stock popped today SHD manufactures tinplate—the tin-coated steel used for can lids and food cans—at its Ansan facility. Founded in 1956, the company has operated for 70 years. The catalyst took shape recently when the company announced a 2 billion won share-repurchase plan, which led to three consecutive days at the daily upper limit. Share buybacks are typically read as price-support measures. With tight float, the concentrated buying interest amplified the move, analysts noted. A regulatory backdrop also plays a role. Stricter delisting rules implemented in J...

Moadata Co., Ltd. (288980) surged to 307 KRW intraday, up 27.92% from the previous close, with trading volume exceeding 8.3 million shares —well above average. Over the same period, the KOSDAQ index was flat. The move was stock-specific, not market-driven. Why This Penny Stock Popped Today Moadata received a management-type-stock designation warning from the exchange on August 12 under KOSDAQ rules. When a stock closes below 1,000 KRW for 30 consecutive trading days, it is designated as a management-type stock the next day. At that time, more than 30 penny stocks on KOSDAQ faced this threshold, and many were subsequently designated. As of the August 13 close, Moadata was trading at 638 KRW, down roughly 97% from its 20,000-KRW IPO price. A single-day 27.92% jump in such a stock typically points to one explanation: low-priced-stock bounce or a concentration of short-term buying pressure. However, no new disclosure or news explaining today's surge has been confirmed;...

Friday morning, August 28, 2026. Last night on Wall Street, semiconductors alone rallied. Despite Nvidia crushing market expectations, the Dow managed just 0.20% higher. The KOSPI had already jumped to 6,912.37 (+1.53%) yesterday afternoon (8/27), pricing in Nvidia hopes before the market. But once the earnings hit overnight, New York stayed subdued. Here's what happened—and what to track in Korean markets today. U.S. Big Three: Essentially a Nasdaq-Only Rally August 27 (ET) U.S. market heat map (S&P 500 snapshot) · green=gainers/red=losers (finviz convention) On August 27, the Dow closed at 53,569.44, +0.20% ; the S&P 500 at 7,730.99, +0.72% ; and the Nasdaq Composite at 26,541.35, +1.57% . On the surface, all three rose. But look deeper and the story shifts. The Nasdaq jumped 1.57% while the Dow eked out 0.20%. That was the exact headline U.S. financial media led with: "Tech alone lifted the S&P 500." In plain terms, Nvidia and the semicon...

Palantir Technologies (PLTR) climbed 4.60% on August 28, breaking through $185 to trade near $185.67. The stock is up over 40% in a month. The timing looks odd. Earnings came out three weeks ago. What's driving the new move? What Wall Street sees today William Blair reiterated its outperform rating on August 27. The report highlights two catalysts: Palantir's Maven Smart System—a Defense Department AI program—is tracking toward a $1 billion annual revenue run rate, and a Pentagon memo allocates up to $244 million in additional funding through March 2027. Maven is expected to receive formal program-of-record status by the end of September. This rally started with second-quarter earnings on August 3. Revenue hit $1.94 billion, up 93% year-over-year and well ahead of the $1.8 billion consensus. The stock gained 29.5% that day alone, approaching its best single-day performance on record. Both businesses accelerating The strength is broad-based. U.S. Commercial re...

Nvidia shares surged about 7% on Aug. 27 (Korea time), trading near $225, after delivering a Q2 earnings beat. On the surface, that's nothing new. Nvidia has beaten expectations in four straight quarters, yet its stock has repeatedly fallen after each announcement. This time was different. Just how much did it beat? FY2027 Q2 (May–July) revenue reached $96.22 billion, up 106% year-over-year. Revenue doubled in a single year. Analyst consensus had been $92.17 billion. Nvidia beat by $4 billion. It marks the 13th consecutive quarter of record revenue. The real engine is data center. That segment alone posted $89 billion in revenue, up 117% year-over-year and accounting for 92% of total sales. Nvidia is now effectively a data-center company. But why didn't the stock fall this time? The previous four quarters saw the stock decline despite strong results, as investors viewed upside as already priced in. This time, the market had one additional number to consider...

GS Holdings (078930) closed at KRW 123,200 on the 27th, marking a new 52-week high. Over three months, the stock has advanced more than 68%. It's uncommon for a holding company to gain two-thirds in just three months. Yet analyst target prices, recently raised, remain in the KRW 100,000 range. The stock has already outpaced these targets. Here's what the numbers show. Are other holding companies rising too? The first question: Is GS rising alone, or are holding companies being re-rated as a group? A look at 3-month returns for four leading Korean holding companies shows: · GS Holdings +68.3% (P/E 14.6) · SK Holdings -15.4% (P/E 25.4) · LG Corporation -30.9% (P/E 24.7) · Lotte Group -5.4% (net loss) The peer median is -15.4%. While three competitors fell, GS stood alone. This isn't a group rally but individual outperformance. Notably, GS trades at the lowest P/E among the four—the cheapest-valued stock gained the most. Valuation alone doesn't explain...

The KOSPI closed at 6,912.37 on August 27, 2026, up 104.16 points or 1.53% from the previous session. On the surface, it was a strong day. But the gains masked significant intraday turbulence. The index surged to 6,996 at the open, a gain of 2.76%. That early optimism faded. By midday, the benchmark had retreated to 6,841, giving back nearly all its gains. Volatility persisted throughout the afternoon before the index recovered toward the day's highs only in the final minutes. Two events pulled the market in opposite directions. Overnight, Nvidia reported results that beat forecasts. Later in the session, the Bank of Korea raised interest rates. The convergence of positive news and a tightening signal created the day's whipsaw. Why Nvidia Beat Expectations Nvidia reported fiscal Q2 revenue of $96.22 billion, up 106% year-over-year and well above the consensus estimate of $92.17 billion. It was the company's 13th consecutive quarter of record revenue. Data cent...
