KOSDAQ opened August 26 with PROTEINA CO.,LTD. (468530) surging sharply. The stock traded near 40,100 KRW, up 14.74% from the prior close of 34,950 KRW —a gain exceeding 5,000 KRW in a single session. The numbers alone tell an incomplete story. Behind them sits a longer narrative. Over the past two months, this stock has had few quiet trading days. The Company PROTEINA was founded in 2015 as a protein-data company. It is headed by Professor Tae-Young Yun from Seoul National University's Department of Life Sciences, with approximately 50 employees. The company's SPID platform observes and analyzes protein-protein interactions at the single-molecule level. The application is straightforward. Pharmaceutical developers require this data to determine whether a candidate antibody binds only to its intended target or cross-reacts, risking side effects. PROTEINA offers this analysis through two formats: a service called PPI PathFinder and a solution called PPI Landsc...

Wednesday morning, August 26, 2026. All three major U.S. indices closed higher last night, and semiconductor shares rallied with them. Yet today's KOSPI isn't a straightforward win. The problem sits in tonight's earnings call. NVIDIA reports quarterly results tonight. Last night's advance was largely a warm-up—investors positioning ahead of the actual announcement. The results aren't in yet. Stocks that rally before earnings often swing sharply in the opposite direction once the numbers land. That shock wave arrives in Korea Thursday morning. U.S. market heatmap (S&P 500) from last night · Green = gains, Red = losses (finviz) Three major indices all finish higher; Dow extends winning streak to three days The Dow Jones Industrial Average closed up 160.24 points (+0.3%) at 53,577.40. The S&P 500 gained 0.32% to 7,677.28, and the Nasdaq rose 0.66% to 26,151.30 on August 25 (U.S. time). The Dow's win marks three consecutive up days. Momentu...

Marvell Technology (MRVL) surged 5.51% on August 25, trading near $241.92, erasing a 3.3% decline from earlier in the week in a single session. The driver was straightforward: two brokerages raised price targets on the same day. Earnings are scheduled for Thursday, two days later. Why the 5% jump in one day Rosenblatt lifted its Marvell price target from $240 to $300 in its first report under a new analyst, maintaining a buy rating. The basis: 29x fiscal 2029 expected earnings. The same day, Susquehanna raised its target from $230 to $265—both firms signaling confidence in Thursday's results. Rosenblatt expects the optical interconnect segment to exceed prior-quarter revenue by 25% or more, and forecasts "another earnings surprise coupled with raised guidance." The implied upside to Rosenblatt's $300 target from current levels exceeds 20%, though that projection rests on the earnings beat materializing. This month's Marvell news didn't start ...

On August 25, AMD shares surged roughly 4% intraday on the NASDAQ, trading in the $474-477 range —representing a near-$20 jump in a single session. The catalyst was neither earnings nor a new product announcement. It was an upgrade from a single brokerage. What happened Raymond James elevated AMD's rating from Outperform to Strong Buy and raised its price target from $565 to $641. The stock climbed 2.5% in pre-market trading, then accelerated to mid-4% gains by early regular session. One figure deserves scrutiny. A $641 target implies nearly 40% upside from the previous close. It represents a single analyst's view, but that gap is rare. The chart shows AMD compressed since July's peak around $580, sliding to $450 in early August before today's move brought it back to the 20-day moving average at $480. It remains below the 60-day moving average at $509. Why now? Analyst Simon Leopold, covering AMD for Raymond James, framed the case around the AI serve...

On August 25, the KOSPI fell to 6,408.82 within the opening hour, marking -4.30% intraday. By day's end, the index closed at +0.68%, 6,742.74 . A swing of nearly 5 percentage points in a single session. Semiconductors did not lead the recovery. Nuclear energy and construction stocks did. Doosan Enerbility climbed 10%, Korea Electric Power Technology surged 20%. A closer look at this one-day reversal, set against three years of price action. How far the index fell, and how far it recovered The KOSPI opened at 6,535.93, down 2.40% from the prior close. A poor start. Overnight, U.S. semiconductor stocks had been swept lower after Nvidia announced higher AI-chip pricing. The selloff carried straight into Korean trading. Early losses deepened. Samsung Electronics and SK Hynix both fell sharply. The intraday low—6,408.82, or -4.30%—arrived within the first hour. This proved to be the session low. Later, the index briefly recovered to the 6,600 level, then retreated to 6,550. Morni...

On August 25, during intraday trading, KNR SYSTEMS Inc. (199430) is trading around KRW 14,300, up 14.95% from the previous close . At the same time, the KOSDAQ Index is moving sluggishly. This isn't a general index rally—it's this stock alone. The entire KOSDAQ hasn't been particularly shaken, yet one stock has jumped nearly 15%. It shows the catalyst for this company is strong. What does this company do? KNR SYSTEMS Inc. was founded in 2000 as a hydraulic precision control specialist. It went public on KOSDAQ in 2024 via the technology listing track. The company has its own lineup of robot drivetrain core components—from hydraulic actuators and hydraulic robotic arms to a standard mobile robot platform. Few domestic companies carry this combination. It has a track record of supplying high-performance actuators to Boston Dynamics. It is also collaborating with Amazon Robotics to jointly develop a robot actuator performance validation system. In late July, it...

Hanwha shares traded near KRW 122,400 on the morning of August 25, representing a 21.67% gain from the previous close. Yet the broader market moved in the opposite direction: KOSPI fell 1.55% that day. While the index retreated, this single stock soared. The explanation lies not in market conditions but within the company itself. There's something different about this stock today. Specifically, it is trading for the first time since undergoing a significant corporate restructuring. Trading halted for nearly a month? Hanwha faced a trading halt from July 30-August 24 due to a proportional share spin-off. The company divided itself into two entities effective August 1. Today, both portions resumed trading on KOSPI: the surviving entity Hanwha relisted with a changed structure, while the newly created Hanwha Machinery & Service Holdings returned as a separate listing. The split allocated net assets on a book-value basis: approximately 76% to the surviving entit...

On Monday, August 24 (U.S. time), Supermicro shares (SMCI) fell -4.22% intraday from the prior close, trading near $35.67. With the previous day's close around $37, the stock slid sharply in a single session. Earnings just hit record levels. Yet the stock tumbled. The reason wasn't domestic—it was Taiwan. Why Taiwan's Prosecutors Are in the Picture On August 24, Taiwan's Jilong District Prosecutors Office indicted nine individuals, including one Nvidia Taiwan employee and two Supermicro Taiwan employees. The charge: illegally exporting U.S. export-controlled AI servers to China. By the numbers: 130 Supermicro B300 servers were ordered. Of those, 74 reached Chinese customers—some via direct shipment, others routed through Indonesia, Japan, and Hong Kong. The remaining 56 were falsely documented as Japan-bound. Taiwan customs detected the irregularities and blocked the exports. Prosecutors said the defendants "conspired for personal gain to illegally e...

On August 24, Micron traded around $900, down roughly 6% to 7% from the previous close of $963.68. The trading session was still in progress, meaning the final decline could widen or narrow. Over recent days, the stock has oscillated around the $900 level. A 6.8% single-day move is significant. Is Micron falling alone? No. Micron, Samsung Electronics, SK Hynix, and the Roundhill Memory ETF (DRAM) have all fallen more than 20% from recent highs. Across the semiconductor sector, $1.5 trillion in market capitalization has disappeared since June 25. Today's decline is not unique to Micron. Questions about the sustainability of AI infrastructure spending are weighing on all three memory suppliers, and today adds a Micron-specific headwind. Today's development: Netlist patent lawsuit Netlist, a memory module manufacturer, filed patent lawsuits against Micron simultaneously at both the U.S. International Trade Commission (ITC) and federal court. The suits target Micr...

Shares of Hanmi Pharm. Co., Ltd. (128940) are soaring near the 540,000 KRW mark, up 29.96% from the previous trading day . The entire move occurred in a single session—a rally of nearly 30% in one day. This move is too large to attribute to ordinary investor flows. At the time of writing, the KOSPI daily return had not yet been confirmed, but index moves of this magnitude are uncommon. The stock is outpacing the broader market. The rally appears driven by company-specific news concerning Hanmi Pharm. itself. The strongest second-quarter results in 11 years Hanmi Pharm.'s preliminary Q2 2026 earnings, announced July 28, show revenue of 467.2 billion KRW, a 29.3% increase year-over-year. Operating profit reached 131.1 billion KRW, representing a 116.9% increase , and net income totaled 84.1 billion KRW, up 95.5%. Both top-line and operating-profit figures mark the company's highest levels since Q4 2015—a span of 11 years. First-half cumulative revenue stands at ...
