September 21, 2026 (local time) saw U.S. markets close at fresh records: the Dow rose 0.71%, the S&P 500 climbed 1.49%, and the Nasdaq surged 2.26%. The broad rally pushed the Nasdaq from 26,522 to 27,122 in a single session, yet the day's semiconductor strength came from an unexpected source—not Nvidia, but Intel and its CPU peers. Intel jumped over 12% in a single day, and AMD crossed the $1 trillion market-cap threshold for the first time. Arm Holdings also surged over 13%. Yet Nvidia, which boasts a far larger market capitalization than all three, gained just 2.30%—a notably smaller advance. The day reversed the usual hierarchy. What drove this shift? And what does it mean for domestic semiconductor and export stocks? Here's what happened. U.S. Markets Close—Nasdaq Hits Record High Overnight market snapshot: S&P 500 heat map (finviz U.S. color scheme: green = gains, red = losses) Market closes for September 21: Index Close Change Dow Jones 52,048.83 +0.71%...

Meta stock surged 12.32% on September 21 (US time) and is now trading at $747.18. The intraday range ran from a low of $679.57 to a high of $749.49—a spread approaching $70. From the prior close of $665.22, the stock has climbed to within striking distance of $750 with trading still in progress. Volume exceeded 32 million shares, roughly double the recent two-month daily average. When that much buying pressure concentrates on a single day, it signals more than a routine bounce. The market as a whole moved on the same news in the same direction. Who raised the target 24%? Wells Fargo is the origin point. Analyst Ken Gaurowski lifted Meta's price target from $640 to $796—a 24% increase— while maintaining an overweight rating. Investing.com and 247wallst.com ran the news in parallel, making this more than a single-source report. The reasoning rested on narrative rather than numbers. Gaurowski cited early user traction for Meta's personal AI assistant, Muse, followin...

AMD shares are rallying sharply in New York trading on September 21. As of early Eastern time, the stock trades around $604, up 7.89% from the previous close of $559.82 . This price level surpasses the prior 52-week high of $584.73 set on June 30. It marks an all-time high. The move stands out even among semiconductor stocks. The numbers alone could suggest just another up day, but the broader trend over the past week tells a different story. Why today's move Two main catalysts. First, Piper Sandler analyst David O'Connor reiterated a $600 price target and outperform rating following the company's recent conference call. His case rests on on-schedule CPU and GPU launch timelines and sustained strong demand relative to supply. Second, AMD announced a roughly 10% price increase for some Q4 AI accelerators and GPUs, citing higher production costs. Price increases typically occur when demand is strong, not when supply is abundant. Current consensus among 55 Wall Str...

On September 21, 2026, KOSPI closed at 7,007.72, up 113.49 points or +1.65% from the prior session. Yet retail investors sold KRW 3.068 trillion in shares that same day. Institutional investors did the opposite—and they've now been buyers for four consecutive trading days. It's not unusual for retail investors to sell on days when the index rises. But when the volume reaches KRW 3 trillion, the pattern warrants attention. Here's what the numbers reveal. KOSPI Reclaims the 7,000 Level in Six Trading Days KOSPI opened higher at 6,938.34, reached an intraday peak of 7,027.58, then pulled back below 6,990 before rallying into the close. Final settlement: 7,007.72, reclaiming the 7,000 threshold for the first time since September 10—six trading days earlier. KOSDAQ moved in sync, closing at 836.27, up 9.15 points or +1.11% . This marks the fifth consecutive day of gains. KOSPI daily chart (Naver Finance) KOSDAQ daily chart (Naver Finance) While Retail Sold ...

On Friday, September 18, 2026, major U.S. indexes closed with mixed results. The Dow Jones fell while the S&P 500 and Nasdaq gained. The same day, U.S. Treasury 10-year yields surpassed 5% once again—a sign that rate pressures remain in play. But semiconductors told a different story. The Philadelphia Semiconductor Index surged 2.78% on its own, outperforming the broader market. Before the Korean market opens, here's what happened overnight on Wall Street. Why the major U.S. indexes diverged Sept. 18 (Fri.) close—indexes divided, but semiconductors led the charge The Dow Jones Industrial Average fell 0.18% to 51,682.64. The S&P 500 gained 0.17% to 7,650.50. The Nasdaq Composite rose 0.39% to 26,522.55. None showed dramatic moves. The broader picture tells a different story for the week. The Dow fell for a third consecutive week, while the Nasdaq finished in positive territory. The story traces back to Tuesday, when the Federal Reserve raised its benchmark rat...

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...
