US-listed Coinbase surged 11.74% in today's session, trading near $194.39. The stock gained more than $20 in a single day—a sharp move. The jump wasn't driven by a single factor. Regulatory approval, Bitcoin price action, and new business partnerships all converged on the same day. What fueled the 11% rally today The primary catalyst was the Securities and Exchange Commission (SEC). On Sept. 17, the SEC implemented a conditional exemption allowing trading in tokenized U.S. stocks—a five-year temporary approval. The exemption applies to systems that trade stocks as tokens on blockchain networks, as well as companies providing liquidity to such platforms. Coinbase has been preparing tokenized-stock services on its own blockchain, Base. Buying interest surged on expectations of a new revenue stream opening up. That said, the exemption doesn't guarantee Coinbase any specific licenses, customers, or immediate revenue—it essentially opens a business opportunity that ...

September 18, 2026: The KOSPI closed at 6,894.23, gaining 178.82 points, or 2.66% in a single session. But the move appears counterintuitive. The night before, the Federal Reserve raised its benchmark rate. Typically, a rate increase makes equity markets flinch. Today was different. The reason is straightforward. The market was not afraid of whether the Fed would act; it was afraid of not knowing what comes next. Once the Fed committed to its decision, that uncertainty evaporated. U.S. Treasury yields and international crude prices both fell, while semiconductor stocks ignited the rally. Index and investor flows — Foreign investors return to net buying after 8 trading days The KOSPI opened with a gap-up to the 6,885 level. Morning trading saw momentum fade, pulling back to 6,830. Afternoon buying returned, pushing the index to a high of 6,914 before settling at 6,894.23. The KOSDAQ ended at 827.12, up 0.60%—a fourth straight session of gains. By the numbers: foreign inves...

Friday, September 18, 2026. Overnight (U.S. time, September 17), the three major U.S. indices rose in tandem. Just one day prior, the market had fallen for four straight sessions following the Federal Reserve's rate increase. Then the momentum reversed. The Nasdaq surged 1.69%—semiconductors and Big Tech led the rally. What to watch today: how much of this rebound the Korean market absorbs. For those who missed the overnight session, here are the numbers, why markets moved, and what it means for Korean equities today. U.S. indices reverse after one day September 17 (U.S. time): All three major indices closed higher in unison. The Dow Jones Industrial Average gained 316.14 points, or 0.61%, to 51,778.04. The S&P 500 rose 85.95 points, or 1.14%, to 7,637.76. The Nasdaq Composite surged 439.87 points, or 1.69%, to 26,418.29. September 17: U.S. three major indices daily change Just one day earlier, on September 16, the picture inverted. The Federal Reserve raised it...

Intel shares rose 9.45% to $110.60 on U.S. markets, a jump of roughly $9.60 from the previous close at $101. Intraday, the stock briefly reached $111.37. Two catalysts drove the move: preliminary discussions between SK Hynix and Intel over memory production at Intel's Ohio semiconductor factory, plus same-day analyst upgrades from two investment firms. Why SK Hynix entered the picture According to reports citing Reuters, SK Hynix is in preliminary talks to produce memory chips at Intel's Ohio fab. The discussions center on leasing part of the facility or entering a joint venture to produce memory in the U.S. This is not the first time this story has surfaced. In July, reports claimed SK Hynix was considering acquiring the Ohio site; SK Hynix then denied any such plan was under way. This time the angle has shifted—from acquisition to leasing or partnership—and no final agreement has been reached. The Ohio fab: what it was supposed to be Intel broke ground on t...

Micron Technology (MU) gained roughly 5.5% on Sept. 17 to trade near $980, compared with the prior close of $926.55. The stock touched an intraday high of $985. At these levels, the market cap stands around $1.1 trillion, with a P/E ratio near 21x—not expensive by semiconductor-leader standards. The natural question: why the rally now, when Q4 fiscal 2026 earnings don't arrive until Sept. 30—still nearly two weeks out? DRAM and NAND prices have already told the story The short answer is that both DRAM and NAND prices hit all-time highs in August. By the time earnings are reported, investors expect confirmation rather than surprise. On Sept. 14, Motley Fool noted that the earnings should verify "that the memory shortage remains intact." Analysts are already forecasting PC DRAM prices could climb 18–23% in the next quarter alone. The revenue swings illustrate the magnitude. DRAM revenue in the prior quarter reached $31.3 billion compared with $7.1 billion a ye...

PSK Holdings closed at 166,902 won on September 17. That's a 42% gain over three months. Over the same stretch, Samsung Electronics dropped 17.7%, SK Hynix fell 31%, and Wonik IPS—the bellwether of chip-equipment stocks—was down 20.8%. The sector was retreating. This one moved the opposite way. The Sector Retreats While PSK Advances Three-month performance across the Korean semiconductor complex: · Samsung Electronics -17.7% · SK Hynix -31.0% · Hanmi Semiconductor -11.8% · Wonik IPS -20.8% · Solbreain -1.3% The peer median is -17.7%. PSK stands alone at +42.0%. A gap that wide doesn't reflect sector dynamics—it points to something specific to the company. Over a full year, both rode the same wave: SK Hynix soared 512% and PSK climbed 337%. But the past quarter has clearly diverged. What the Company Makes PSK builds ashing equipment—machines that burn off photoresist residue left on semiconductor wafers after patterning. It commands a 41% global market sh...

Intel shares surged more than 5% on September 16, breaking above $102, after Reuters reported that SK Hynix and Intel are in discussions about jointly manufacturing memory chips in the United States. The negotiations mark a potential turning point for both chipmakers' U.S. operations. If realized, this would be SK Hynix's first memory production outside South Korea—and it would happen by leasing capacity from a rival, no less. What the two sides are discussing Reuters reported two possible structures. One involves SK Hynix leasing part of Intel's Ohio semiconductor fabrication plant. The second is a joint venture that would include SK Hynix, Intel, and cloud computing firms seeking stable memory supply. Neither arrangement is confirmed. SK Hynix said it is "exploring various options to strengthen competitiveness, but nothing has been decided." Intel declined to comment on the talks themselves, though it said its Ohio facility plans remain on track. ...

KOSPI closed at 6,717.97 on September 16, up 90.71 points or 1.37% . The gain stands out given overnight developments: U.S. 10-year Treasury yields topped 5% and oil prices surged to their highest in roughly four months—typically headwinds for equity markets. Yet by day's end, semiconductors had carried the broader index higher. The rally marked the first advance in five sessions, propelled by semiconductor-sector momentum linked to two separate developments around SK Hynix. Index and flows KOSPI opened at 6,611.24, dipped to 6,598.87 early in the session, recovered to near 6,680 before retreating again, then pushed higher in the afternoon to close at session highs. Institutional investors led the rebound, purchasing a net KRW 1.2 trillion—their first net-buying day in four sessions. Foreign investors remained sellers, offloading a net KRW 1.68 trillion and extending their selling streak to six consecutive days. Retail investors net-sold KRW 1.19 trillion, resuming sell...

U.S. markets extended losses for a second consecutive session on September 15. The Dow Jones fell 0.63%, S&P 500 dropped 0.45%, and Nasdaq Composite declined 0.78%. But the most striking figure isn't the indices—it's the 10-year Treasury yield. It climbed to 5.041% intraday, marking its highest level since 2007. Crude oil rallied in tandem. These moves provide essential context as Seoul markets prepare to open today. U.S. Major Indices Extend Losses On September 15, the Dow Jones Industrial Average closed down 328.09 points (-0.63%) to 52,093.11. The S&P 500 fell to 7,585.73 (-0.45%), and Nasdaq Composite declined to 25,981.57 (-0.78%). Sept. 15 (U.S. time): U.S. three major indices daily changes This follows declines a day earlier: Dow -0.29%, Nasdaq -0.56%, S&P 500 -0.48%. That marks two straight days of weakness across the board. Two factors are driving the selloff. First, there's growing self-scrutiny within the AI sector. Dario Amodei, CE...

MicroStrategy (MSTR) fell to $128.29 intraday on September 15 (U.S. time), marking a -6.32% decline from the prior close. The drop had nothing to do with earnings or company announcements—Bitcoin itself weakened. What triggered the selloff: The Clarity Act vote The Senate was scheduled to hold a procedural vote on the Digital Asset Market Clarity Act that afternoon. If passed, it would establish the first coherent regulatory framework for digital assets. But Republicans rejected Democratic amendments hours before the vote, widening the gap between the two sides. Polymarket odds on passage fell from 30% the day before to 14% by morning—cut in half. The market read it as disappointing. Bitcoin fell to the $76,000 range, and oil climbed to $103 per barrel, prompting inflation concerns. With the Federal Reserve's rate decision looming on September 16, investor sentiment was especially fragile. MicroStrategy wasn't alone If MicroStrategy had been isolated, that would ...

Intraday on September 15 (U.S. time), Coinbase (COIN) shares fell to the $179 range from the previous close of $191.45. The decline ran roughly -6% . As trading continues, this figure may shift through the close. The selloff stems neither from earnings nor a new scandal. The U.S. Senate votes this afternoon at 2:15 p.m. ET on a cryptocurrency regulatory bill. Current pricing Previous close: $191.45. Intraday low touched $178; shares currently trade between $179–$180. The 52-week range spans $139.11 to $402.16. Current levels sit above the low but well short of the high's midpoint. For context: the day prior (September 14), the opposite occurred. Compass Point upgraded its rating from Sell to Neutral, and the stock rose 6%. What's at stake in today's Senate vote The bill is the CLARITY Act, cryptocurrency market-structure regulation. Today the Senate holds a cloture vote—a procedural motion to bring the bill to the full chamber. Passage requires 60 votes. W...
