Nikkei 225

Thursday began with a hangover across Asian equity markets. After several days of record-breaking gains in technology and semiconductor stocks, reality set in. Indexes drifted lower—not in a panic, not in a crash, but steadily enough to leave little doubt: the rally is taking a pause.

Several factors contributed to the shift. The main one is simple exhaustion. After the Nikkei reached a fresh all-time high and South Korea’s KOSPI approached its own peaks, investors decided it was time to take profits—especially against a backdrop of increasingly unsettling news.

There were also more concrete triggers. Comments from the Governor of the Bank of Japan regarding possible interest-rate hikes. Mixed results from Broadcom that weighed on the entire semiconductor sector. Ongoing uncertainty surrounding U.S.-Iran negotiations. Together, these factors created a cocktail that Asian markets found hard to stomach.

S&P 500 futures, which often set the tone for global trading, fell 0.4% in after-hours trading. American investors are taking profits as well. The example is contagious.

The Japanese market, which was celebrating only yesterday, found itself deep in the red today. The Nikkei 225 lost 1.9%, while TOPIX, the broader Tokyo Stock Exchange index, fell 1.4%. These are significant moves—the kind that prompt analysts to revisit their forecasts.

What happened?

First, profit-taking. The Nikkei hit record highs this week, and many investors who bought stocks a month or two ago saw their portfolios rise by 20–30%. The temptation to lock in real gains rather than admire paper profits proved stronger than faith in further upside.

Second—and perhaps more importantly—there were comments from Bank of Japan Governor Kazuo Ueda. Speaking at a seminar on Wednesday, he said something markets were not expecting, at least not yet.

Ueda warned that inflation in Japan could...

Asian stock markets delivered a pleasant surprise on Wednesday, staging a remarkable rally despite a global backdrop that offered little reason for optimism. The Middle East remained engulfed in conflict. Iran and the United States exchanged airstrikes for the third time in a week. Oil prices climbed. Diplomatic negotiations stalled. Diplomats stayed silent while military forces took action.

Under such circumstances, most markets would be expected to fall—or at least pause in anxious anticipation. But Asian markets ignored the script. They rose. And not just modestly: Japan’s Nikkei 225 surged to an all-time record high, surpassing a milestone many believed was unattainable after three decades of economic stagnation.

What happened? Have investors stopped worrying? Or are they seeing something that analysts obsessed with geopolitics are missing?

As is often the case, the answer is more complicated. On Wednesday, Asia demonstrated a remarkable ability to tune out negative headlines and focus on the factors working in its favor. And there are plenty of them: a technology boom, government stimulus measures, and weak economic data that paradoxically reinforce expectations for accommodative monetary policy. Together, these factors created a cocktail strong enough to outweigh fears of escalating military conflict.

The star of the day was Japan’s Nikkei 225. The index climbed nearly 3% to reach 68,645.5 points—an all-time high in its history dating back to 1950.

To appreciate the significance of this achievement, it helps to remember where Japan stood three decades ago. In 1990, the Nikkei collapsed following the bursting of the country’s asset bubble. Since then, despite periods of recovery and decline, the peak reached in 1989 had seemed permanently out of reach.

Now, a new record has been set.

The Nikkei was not alone in its triumph. The broader...

Asian markets on Tuesday resembled a patchwork quilt stitched together from conflicting signals. Japan’s Nikkei 225 and South Korea’s KOSPI, which had been celebrating record highs just a day earlier, pulled back by roughly 2%. Hong Kong’s Hang Seng, by contrast, gained 0.8%, lifted by heavyweight technology stocks. Chinese indexes moved in opposite directions, Australia’s market fell following hawkish comments from the central bank, and Indian futures pointed to further losses. All of this unfolded against a backdrop of uncertainty surrounding Iran and profit-taking in the semiconductor sector. Tuesday was a reminder that markets cannot rise forever.

Japanese and South Korean equities were among Tuesday’s biggest casualties. Both indexes retreated about 2% from the record levels reached in previous sessions. The reason was as old as the market itself: profit-taking. After an impressive May rally fueled by optimism around artificial intelligence, investors decided it was time to lock in gains.

May was a triumphant month for Asian chipmakers. SK Hynix joined the ranks of trillion-won companies, Samsung reached fresh all-time highs after resolving a labor dispute, while Renesas and Rohm posted double-digit gains. Nvidia added fuel to the rally on Monday by unveiling new AI-related products. But every rally, no matter how powerful, eventually runs out of steam. Tuesday was the day the bulls took a breather.

The decline in South Korea was particularly notable because it coincided with disappointing macroeconomic news. Consumer inflation in May reached a 26-month high, exceeding expectations. This immediately strengthened expectations that the Bank of Korea could raise interest rates again before year-end. Higher rates are generally unfavorable for equities, especially technology stocks, which are highly sensitive to borrowing costs. Korean investors responded to the inflation data by selling.

Asian markets on Wednesday looked like two parallel worlds existing within the same universe. In the first world — inhabited by memory chip makers and AI accelerator manufacturers — euphoria reigned. Japan’s Nikkei 225 surged to a new all-time high, climbing above 66,428 points. South Korea’s KOSPI delivered an even more dramatic move, soaring five percent in a single session to reach an unprecedented 8,457 points. Shares of SK Hynix jumped nearly fourteen percent, pushing the company’s market capitalization above one trillion dollars for the first time in history.

In the second world — the world of geopolitics, oil prices, and Middle Eastern negotiations — anxiety dominated. Brent crude hovered around ninety-nine dollars a barrel, Chinese indices declined, and investors nervously scanned the horizon for an answer to a single question: would there be peace with Iran, or more bombing campaigns ahead?

There are moments in corporate history that divide eras. For SK Hynix, Wednesday became such a moment. A near fourteen-percent rally in a single session pushed the company’s market capitalization beyond the psychological trillion-dollar mark.

This is more than just a symbolic number. It is an entry ticket into an exclusive club where only two other memory manufacturers reside alongside SK Hynix: Samsung Electronics and Micron Technology. Three companies, three pillars supporting the global memory industry.

The reason behind the rally is both simple and monumental. The world is entering an era in which artificial intelligence requires enormous volumes of high-speed memory. Every new data center, every large language model, every Nvidia accelerator devours gigabytes and terabytes of HBM memory — a segment where SK Hynix holds a leading position.

And as technology giants like Google and Amazon announce fresh investments in AI infrastructure, the Korean memory maker can calmly count its...

Asian stock markets on Tuesday looked like a chessboard where the black and white squares had been mixed together without any logic. Japan declined, China fell, Australia and Singapore slipped into the red. But in the middle of this sea of red indices, like an iceberg rising above the waves, stood the KOSPI — South Korea’s benchmark index hit a new all-time high, surging above 8,131 points. Hong Kong, lifted by a rally in chipmakers, also closed higher. This market schizophrenia perfectly reflects the current moment: geopolitics is pulling markets down, technology is pushing them up, and investors are swinging between fear of Iranian bombs and greed for artificial intelligence.

New U.S. strikes on missile positions and vessels in southern Iran, revealed on Monday, hit the markets like a bucket of cold water poured over the smoldering embers of optimism. Just on Sunday, markets were celebrating hopes for peace. As recently as Monday morning, oil had fallen below $100 a barrel, Asian indices were climbing, and traders were pricing in a swift reopening of the Strait of Hormuz. Today, everything looks different. Brent is back near $98, while WTI hovers around $92. Oil prices have bounced back, reminding everyone that the war is not over — it has merely paused.

Washington describes the strikes as defensive. The wording matters: it leaves room for diplomacy. Had the attacks been labeled offensive, markets would have interpreted them as escalation and reacted far more aggressively. But even “defensive” bombings during ongoing negotiations in Doha send a message. A message that diplomacy is stalling, that the sides cannot reach an agreement, and that military force remains the primary argument. And although Trump continues to say the talks are “going well,” markets have learned to...

Monday began on Asian stock exchanges in a way not seen for a very long time. Japan’s Nikkei 225 soared to the skies, hitting a fresh all-time high of 65,408 points. The TOPIX followed closely behind, also rewriting the record books. Chinese indexes moved higher. Australia, Singapore, and India all painted their screens green. And all of this unfolded against the backdrop of a U.S. market holiday, with the world’s biggest players absent from their desks. Left to themselves, Asian markets staged a rally driven by the intersection of two powerful forces: renewed optimism surrounding artificial intelligence and hopes for an end to the Iran conflict.

Japan’s stock market traded on Monday as if no global crisis existed. The Nikkei 225 gained more than three percent during the session, reaching a level that would have seemed фантастical just a year ago. TOPIX, the broader gauge of Japan’s economy, climbed to nearly 3,954 points, also setting a historic record. This was not merely growth — it was a display of strength.

The driving force behind Tokyo’s rally was shares of companies tied to semiconductors and artificial intelligence. Renesas Electronics and Rohm both surged by ten percent. This was not abstract optimism but a direct spillover from Wall Street, where U.S. semiconductor companies staged their own rally late last week after upbeat earnings and forecasts. Nvidia set the tone, and now Japanese suppliers and partners have picked up the baton.

Japan, long viewed as a fading economic power trapped in deflation, has suddenly found itself in an ideal position to profit from the AI boom. Japanese firms produce critical components for chips — substrates, chemicals, and precision equipment. No TSMC or Samsung factory can operate without them. And as global demand for computing power...
