Samsung's August Surge: Foreign Capital Floods In While Its Own Chip Chief Urges Caution
Published on 08/16/2026 at 17:31 | Redaktion boerse-global.de
The numbers coming out of Seoul this month are staggering by any measure. Samsung Electronics shares climbed 7.4 percent on Friday alone, capping a seven-day stretch that has left the stock up 19 percent. Year to date, the gain stands at 130 percent, and over the trailing twelve months, the equity has appreciated a remarkable 288 percent.
Yet for all the euphoria, the company's own semiconductor chief is pouring cold water on the celebration. Jun Young-hyun, who heads the DS division, estimates that only 30 percent of current results stem from Samsung's own capabilities. The remaining 70 percent, he argues, is simply the tailwind of an industry-wide supercycle that could reverse as quickly as it arrived.
Foreign buyers dominate while local retail steps aside
The rally's engine is unmistakably foreign capital. Over the past week, international investors poured a net 5.6 trillion won into the so-called "S7" basket of Korean blue chips, with Samsung Electronics absorbing 2.8 trillion won of that total. Together, Samsung and SK Hynix accounted for more than 71 percent of all foreign net buying on the Kospi.
The preceding week painted a similar picture. The Kospi climbed for five consecutive sessions, advancing 11.5 percent, as overseas investors scooped up roughly 6.55 trillion won in Korean equities. Samsung Electronics saw net foreign purchases of 2.28 trillion won, while SK Hynix drew 2.43 trillion won. The foreign ownership stake in Samsung has now risen to 46.80 percent.
Korean retail investors, meanwhile, have been net sellers throughout, cashing in on the surge. But some are betting with borrowed money: margin debt climbed from 27.44 trillion won to 30.93 trillion won in the first half of August, a signal that leveraged positions are building on hopes the rally extends. KB Securities analyst Kim Dong-won suggests memory stocks could face a re-rating beginning in the third quarter.
Should investors sell immediately? Or is it worth buying Samsung Electronics?
Record profits, record payouts on the horizon
The fundamental backdrop is undeniably strong. Samsung reported second-quarter operating profit of 89.5 trillion won on revenue of 171.5 trillion won, with the semiconductor division alone contributing 89.2 trillion won to the bottom line. The chip unit's profit surged 250-fold year over year.
That cash generation is fueling speculation of historic shareholder returns. Weekend reports suggest Samsung and SK Hynix could jointly return up to 300 trillion won — roughly $212 billion — to shareholders. Samsung has already committed to distributing 50 percent of its free cash flow between 2024 and 2026, which analysts estimate could translate into as much as 200 trillion won. KB Securities sees a dividend yield of over 7 percent as achievable.
The company is also investing heavily to defend its position. Research and development spending reached 27.3627 trillion won in the first half of 2026, up sharply from 18.06 trillion won a year earlier. Capital expenditures hit a record 28 trillion won. Two notable hires underscore the AI focus: Han Bo-hyung, formerly of Seoul National University, joins as a fellow for AI model development, while Hahn Tai-rin arrives from Meta as Executive Vice President to build AI-ready data infrastructure.
A $200 billion bet and a resurgent DRAM franchise
Thursday brought word of a massive strategic collaboration with Broadcom, valued at $200 billion, targeting memory and foundry technologies for next-generation AI infrastructure. The deal ranks among the largest announced in the company's recent history and comes as competition intensifies — Nvidia had just struck a multi-year partnership with the SK Group worth up to $500 billion for HBM supplies and AI factory construction.
Samsung's technology roadmap is advancing as well. The company achieved an 80 percent "golden yield" on its sixth-generation HBM4 chips on August 11, four months ahead of schedule and a marked improvement from the sub-60 percent yield at launch in February. Mass production has been running since February at 13 gigabits per second. At the Future of Memory and Storage conference, Samsung also unveiled "zHBM," a concept stacking HBM directly vertically over AI accelerators, along with V10 BV-NAND featuring over 400 layers.
The market is taking notice. Counterpoint Research data shows Samsung reclaimed the global DRAM lead in the second quarter of 2026 with a 39.4 percent market share, leaving SK Hynix at 26 percent. Mirae Asset Securities analyst Kim Young-gun raised his price target on Friday, projecting third-quarter operating profit of 120 trillion won on rising DRAM prices and growing foundry orders.

The gaps in the armor
Still, the picture is not uniformly bright. In high-bandwidth memory, Samsung trails badly: SK Hynix commanded 62 percent of the HBM market in the first half of 2025, while Samsung managed only 17 percent and Micron 21 percent. The foundry business is another sore spot — capacity utilization at its 8-inch wafer plants fell below 50 percent in the second quarter, with roughly 30 percent of machinery idled. Full reactivation isn't expected until the first quarter of 2027.
The stock's trajectory reflects this duality. At 274,500 won, Samsung trades about 27 percent below its 52-week high of 374,500 won, reached in June. That gap could represent upside if the AI memory cycle persists — or a warning that the market has already priced in perfection. Friday's 2.4 percent gain, triggered by SanDisk's projection of roughly 80 percent gross margins by 2030 and the Broadcom news, suggests investors remain hungry for catalysts.
For now, the market's verdict is clear: foreign money is betting big on Samsung's memory boom, its payout promise, and its AI ambitions. The cautionary note from its own chip chief, however, serves as a reminder that in semiconductors, cycles turn — and the 70 percent of current profits riding on the industry's supercycle could evaporate when the weather changes.
