Korean Kolmar's stock is trading around 137,800 won today, climbing back toward its 52-week high of 144,000 won. What's interesting is that Cosmex, which operates in the same cosmetics ODM sector and has larger revenue, saw its stock rise only +10% over the past year , while Korean Kolmar's stock jumped +71% in the same period. I dug into why there's such a temperature gap between companies that manufacture cosmetics on behalf of other brands. Did the whole sector rise, or is Korean Kolmar just exceptionally strong? First, I need to check whether this is just Korean Kolmar's story, or if the entire K-beauty ODM sector benefited equally. Looking at the 3-month returns alongside three other companies in the same sector, here's what I see: · Korean Kolmar +51.1% (1-year +71.0%, P/E 26.0x, Operating Margin 8.8%) · Cosmekaco Korea +82.2% (1-year +119.5% , P/E 32.2x, Operating Margin 13.0%) · Cosmex +42.3% (1-year +10.1%, P/E 24.0x, Operating Margin 8...

On August 20, 2026, the KOSPI index closed at 6,852.58, jumping 5.89% in a single day. The index had plunged 5.80% the day before, and today it nearly recovered the entire loss. But the real story here isn't the index—it's who was doing the buying and selling. Retail investors who snapped up ₩4.6 trillion worth on yesterday's crash unloaded ₩2.2 trillion today, while foreign investors, who had dumped ₩3.5 trillion yesterday, came back in to buy ₩1.7 trillion. Talk about a complete reversal in 24 hours. KOSPI seller-buyer breakdown on crash day (8/19) and rally day (8/20)—personally compiled and created Index and money flow, by the numbers The KOSPI index gapped up from 6,680, touched a high of 6,904.55 (+6.70%) during the session, then gave back some of those gains to close at 6,852.58. The rally was so large that it triggered the 24th buy-side circuit breaker of the year. Given that the sell-side breaker had been hit the day before, it was unusual to see both...

Today, Ingenia Therapeutics (Reg.S) (950260) has surged again in a major way. The current price is around 18,330 KRW , with gains up +30.00% —and climbing. Given that this stock has already experienced multiple swings in just three trading days since its KOSDAQ listing, I'm sure many of you are wondering, "What does this company even do that makes it move like this?" A Roller Coaster Four Days After Listing—Here's the Journey So Far Ingenia Therapeutics listed on KOSDAQ on August 18. The IPO price was set at 12,000 KRW, but on listing day itself, it dipped below that early in the session before staging a dramatic turnaround to close at 17,990 KRW (+49.92%) on its first day. The next day, the 19th, it posted double-digit gains during the session, maintaining its volatility, and today (the 20th) it's surging again, hovering around +30% . Being a newly listed stock with limited float, supply and demand dynamics can get skewed easily—that's the na...

Genentech's stock surged nearly 29% during today's trading session , climbing to the 3,200 won range. What was trading at 2,400 won just yesterday skyrocketed to near the daily limit in a single day. When you see a biotech company focused on gene and protein therapies jump this suddenly, you naturally wonder: "What just happened?" Did Today's Surge Hit the Whole Market, or Just Genentech? The KOSDAQ has been on a bullish run over the past month, led by biotech and growth stocks. But the index itself never swings 30% in a single day. Given that KOSDAQ typically moves around 1% daily, Genentech's move is clearly a company-specific story , not a broader market shift. Companies in the same gene therapy space—like Shinlabs, Apexigen, and Toolgen—have historically rallied as a group when one gets good news. So we need to check the supply-and-demand picture after market close to see whether today's move is a Genentech-only thing or a theme that's ...

Good morning, August 20, 2026. Yesterday (August 19), the KOSPI dropped 398.66 points (-5.80%) in a single day, closing at 6,471.17, with a sell-side circuit breaker even triggered during the session. But here's the irony—the very market that caused all this, US stocks, staged a simultaneous rally that night (August 19 local time). The Dow, Nasdaq, and S&P 500 all bounced back hard when the US Treasury Department announced it would expand its long-term Treasury buyback program. The relentless rate hike pressure that had been suffocating markets finally eased. Today, we'll be watching closely to see if the domestic market can recoup yesterday's losses in full.

On August 20, 2026, MicroStrategy (MSTR) stock jumped 11.90% on U.S. markets and is now trading around $103.53. Just yesterday on the 19th, it had already rocketed 14.05% to $105.52, so we're looking at back-to-back double-digit rallies—a rare sight. At this point, the company is less of a software vendor and more like a publicly traded Bitcoin trust. So if you want to know why the stock jumped, you've got to watch Washington and Bitcoin prices before you even glance at earnings. Why did it pop today? The direct trigger was a crypto policy meeting at the White House on August 19. President Trump convened SEC Chair Paul Atkins, CFTC Chair Michael Sellig, and crypto industry leaders from Coinbase, Ripple, Gemini, and Robinhood. The market saw this as a signal that regulatory uncertainty is clearing , and Bloomberg noted that Bitcoin had its biggest move since March leading into the meeting. When Bitcoin rises, MicroStrategy's stock typically swings even harder....

Marvell stock (MRVL) is up 10.77% today, trading around $239.27—a double-digit pop that stands out against a quiet day in semiconductors overall. The reason is straightforward: this morning, Marvell filed that Google just received warrants to purchase—not $122 million in company stock, but a whopping $12.2 billion worth. And that's why the market is celebrating. What exactly happened? Back on July 29th, Marvell and Google signed a commercial agreement to jointly develop custom chips. Then on August 18th, Marvell filed an 8-K disclosing that it issued Google warrants to purchase up to 58.97 million shares at $206.58 per share —totaling $12.2 billion if fully exercised. The news hit like a spark: Marvell jumped double digits in premarket trading and kept the momentum rolling through the regular session. But here's the kicker—Google won't exercise all those warrants at once. In year one, only about 1.36 million shares will vest equally each quarter. The rest unlock...

On August 19, 2026, the KOSPI index closed at 6,471.17. In just one day, it fell 398.66 points (−5.80%) , and circuit breakers were even triggered mid-session. But the number that stood out most that day wasn't the index decline itself. It was that while foreigners and institutions were selling off together, retail investors alone bought over ₩4.6 trillion worth. Let me trace why these two sides moved in completely opposite directions as the market collapsed. Why Did the Index Collapse Like That? The KOSPI started at 6,528.77, already down nearly 5%, and fell as low as 6,400.81 (−6.83%) during the session. Early on, it briefly recovered to 6,614.39, but selling pressure returned and it finally closed at 6,471.17. That day marked the 48th circuit breaker event on the KOSPI, with 25 of those being sell-side triggers. Circuit breakers are safety mechanisms that lock algorithmic trading for 5 minutes when futures prices move sharply in a short timeframe—the fact they were tri...

Bionia stock headed straight to the upper limit this morning. It surged to 9,190 won, up 29.99% from the previous trading day , but of all days, KOSPI plummeted over 4% right at the open and even triggered a sell-side circuit breaker, while KOSDAQ started down 2%. The fact that this stock alone hit the upper limit while the entire market collapsed tells us this move isn't about market sentiment—it's something that happened purely within this company itself. Two pieces of news broke this morning. First, Q2 earnings hit record highs for the quarter. Second, the company's hair loss research results were published in an international academic journal. With earnings and new drug news hitting on the same day, it looks like buying pressure flooded in all at once. What kind of company is Bionia? It started in 1992 as Korea's first biotech venture. It was the first to commercialize gene amplification technology (PCR) domestically, and now beyond its existing diag...

Good morning, August 19, 2026. Last night—August 18 local time—New York's big three indices all fell in step: Dow -0.22%, S&P 500 -0.69%, Nasdaq -1.33%. But the real bloodbath was in semiconductors. The Philadelphia Semiconductor Index (SOX) cratered -4.98% in a single session, with SK Hynix ADR diving -9.19% and Micron sinking all the way to -6.99%. The culprit? Treasury yields. The US 30-year Treasury rate climbed to 5.34% intraday, breaking a 19-year high—and doing it again in just one day, no less. Yesterday, the Kospi soared to 7,216 intraday on strong semiconductor export figures, but then got hammered down to 6,869 by institutional selling before closing. Today, those overnight declines in chip leaders will be baked right in from the open. This piece walks you through last night's damage in New York and the key flashpoints that could rattle the Kospi today.
