South Korea’s benchmark Kospi index has tumbled into bear market territory just weeks after becoming the world’s best-performing major equity market, underscoring how quickly investor sentiment has shifted away from artificial intelligence-related stocks and exposing the risks of an index heavily concentrated in a handful of semiconductor companies.

The Kospi fell more than 5% on Wednesday, leaving it more than 20% below the record high it reached on June 19, according to LSEG data, the conventional threshold for a bear market. The benchmark recovered modestly on Thursday, ending slightly higher after a volatile trading session.

The sharp reversal comes after an extraordinary rally driven almost entirely by enthusiasm for AI infrastructure spending, which propelled South Korean chipmakers to record valuations. As investors reassessed expectations for AI-related earnings growth, those same stocks have become the primary source of the market’s decline.

Market strategists say the speed of the correction reflects changing investor positioning rather than a collapse in the long-term outlook for artificial intelligence.

“South Korea’s recent drawdown has been driven by heightened AI skepticism on the part of global investors, coupled with extreme market concentration,” said Manishi Raychaudhuri, Chief Executive Officer of Emmer Capital.

The Kospi’s dependence on a small number of technology companies has amplified both its gains and its losses.

Data from Emmer Capital show that Samsung Electronics and SK Hynix together accounted for more than half of the index’s weighting as of June, making the benchmark unusually sensitive to swings in investor sentiment toward memory chips and AI hardware.

That concentration helped the Kospi outperform most global markets during the AI boom but has also intensified the current sell-off as investors rotate away from semiconductor stocks.

“The correction has been driven more by positioning than by a deterioration in fundamentals,” said Jung In Yun, founder of Fibonacci Asset Management Global.

“Korean equities had become one of the most crowded AI trades globally after a very strong rally, so it did not take much to trigger profit taking.”

He added that broader market uncertainty and expectations that corporate earnings upgrades may slow have also encouraged investors to lock in profits after the market’s exceptional gains.

Nevertheless, Jung described the decline as “a healthy reset rather than a fundamental change in the outlook.”

Market Structure Amplifying Volatility

Some analysts believe structural changes in financial markets are contributing to larger and more frequent swings in equity prices.

Peter Kim, Global Investment Strategist at KB Financial Group, said modern markets have become increasingly influenced by short-term trading flows rather than traditional valuation analysis.

“The gamification of finance has led to such gyrations driven less by fundamentals but by news flows and fads,” Kim said.

He pointed to the growing influence of retail investors, leveraged exchange-traded funds (ETFs) and the concentration of capital in AI-related companies as factors making market swings of 5% to 10% increasingly common.

Reflecting that heightened volatility, the Kospi Volatility Index has surged more than 200% since the beginning of the year.

Strong Earnings Fail To Reassure Investors

The sell-off has occurred even as South Korea’s largest semiconductor companies continue reporting strong financial results. Samsung Electronics earlier this week posted robust quarterly earnings, while memory chip prices have continued to strengthen as demand from AI data centers remains elevated.

Despite those positive developments, Samsung’s shares declined sharply after investors questioned whether the pace of AI infrastructure investment can continue indefinitely.

“The market is questioning the pace of earnings growth rather than the sustainability of AI demand itself,” Jung said.

“This distinction is important because it suggests we are seeing a valuation adjustment rather than the end of the AI cycle.”

In other words, investors appear to be reassessing how much future growth is already reflected in semiconductor share prices rather than abandoning expectations that AI spending will continue over the longer term.

However, industry specialists say the underlying outlook for memory manufacturers remains favorable despite the recent decline in share prices.

Rolf Bulk, Head of Semiconductors and Infrastructure at Futurum Group, said memory prices increased between 50% and 80% sequentially during the second quarter, with additional price increases expected later this year. The sharp rise reflects continuing shortages of high-bandwidth memory (HBM) and advanced DRAM products used in AI servers, where demand has consistently exceeded available supply.

Bulk said the industry’s fundamentals remain supported by a multi-year supply imbalance and long-term purchasing agreements with hyperscale cloud providers investing billions of dollars in AI infrastructure.

KB Financial Group’s Kim reached a similar conclusion, arguing that the earnings visibility of major semiconductor manufacturers makes the current correction attractive for investors with a longer investment horizon.

“Fundamentals and visibility of earnings makes the current correction an opportunity for those who can withstand the short-term volatility,” he said.

Rally Remains Intact Despite Correction

Although the Kospi has now entered bear market territory from its recent peak, the broader performance of South Korean equities remains exceptionally strong. The index is still up more than 70% this year after gaining over 75% last year, making it one of the world’s best-performing equity markets over the past two years.

The correction therefore follows an extraordinary appreciation in share prices that had pushed valuations to levels where investors became increasingly sensitive to any signs of slowing momentum.

Analysts say the current decline illustrates one of the principal risks facing markets driven by thematic investing. When a small number of companies dominate an index because of enthusiasm surrounding a single investment theme, shifts in sentiment can produce disproportionately large moves across the broader market even when corporate fundamentals remain relatively healthy.

What Could Drive A Recovery?

While analysts expect volatility to remain elevated in the near term, many continue to view South Korea as one of the key beneficiaries of the global expansion in artificial intelligence infrastructure.

Jung said international investors are likely to return once broader market sentiment stabilizes.

“While volatility may persist in the near term, I believe the medium-term outlook remains constructive,” he said.

“Once global risk sentiment stabilizes, foreign investors are likely to revisit Korea given its central role in the global AI supply chain.”

Several near-term catalysts could also influence investor sentiment.

Bulk said the planned U.S. listing of SK Hynix on Friday could improve investor interest in memory chip producers by broadening the company’s international shareholder base and increasing its visibility among global institutional investors.

Analysts will also closely monitor second-quarter earnings presentations from SK Hynix and Samsung Electronics later this month.

Constructive guidance from management on demand for AI memory products and confidence that the current pricing cycle will remain strong through the second half of 2026 could help restore investor confidence in semiconductor shares and support a broader recovery in the Kospi.

Goldman Sachs has secured mandates to oversee a combined $70 billion in retirement assets for Verizon Communications and Lockheed Martin, strengthening its position in one of the fastest-growing segments of the investment management industry as large corporations increasingly outsource the management of employee retirement savings.

The mandates rank among the largest outsourced retirement asset awards announced in recent years and underscore a structural shift in how some of America’s biggest employers manage pension funds and defined-contribution retirement plans.

According to Goldman Sachs, the appointments cover approximately $30 billion in pension assets belonging to Verizon and Lockheed Martin, as well as $40 billion in Verizon’s defined-contribution retirement plans, which primarily consist of 401(k) accounts.

The latest wins expand Goldman’s presence in the outsourced chief investment officer (OCIO) market, where asset managers assume responsibility for constructing portfolios, allocating capital, selecting external managers, overseeing risk, and adjusting investment strategies on behalf of institutional clients.

The business has become increasingly important across the financial industry as corporations contend with more complex investment environments, heightened market volatility, higher interest rates, changing regulations and growing allocations to private markets such as private equity, private credit, infrastructure and real estate.

Many companies are now choosing to delegate day-to-day portfolio management to specialist firms with global research capabilities and access to a broader range of investment opportunities rather than maintaining large in-house investment teams.

The trend is reshaping institutional asset management and creating an increasingly lucrative business for global investment firms.

Stable Fees In An Unpredictable Market

The mandates represent more than an increase in assets under management for Goldman Sachs. Analysts believe they also reinforce the firm’s long-term strategy of expanding businesses that generate recurring fee income, helping reduce its dependence on investment banking and trading operations, whose earnings can fluctuate significantly with market conditions.

Unlike advisory work on mergers or capital raisings, or revenue from securities trading, retirement mandates typically span many years and produce predictable management fees regardless of short-term market cycles.

That stability has made the OCIO business one of the industry’s most fiercely contested markets.

Global investment firms, including BlackRock, Russell Investments, and Mercer, are competing aggressively for a share of the multitrillion-dollar retirement assets managed on behalf of pension funds, corporations, universities, foundations, and other institutional investors. Winning large mandates from household-name companies such as Verizon and Lockheed Martin not only increases assets under management but also enhances an asset manager’s reputation when competing for future institutional business.

The awards also show that institutional investors are reducing the number of firms managing their assets. Instead of dividing portfolios among numerous investment managers, many plan sponsors now prefer to consolidate responsibilities with a single adviser capable of managing sophisticated investment strategies across both traditional and alternative asset classes.

Marc Nachmann, Goldman’s Global Head of Asset and Wealth Management, said that the trend is becoming more pronounced.

“Large plan sponsors are consolidating responsibilities with one partner with the investment expertise and depth of platform to manage their bespoke needs,” he said.

His comments point to a broader evolution in institutional investing. Modern retirement portfolios are no longer built primarily around publicly traded stocks and bonds. Many now include private equity, infrastructure projects, private credit, hedge funds and other alternative investments that require specialized expertise, extensive due diligence and ongoing oversight.

As investment strategies become more diversified, many employers have concluded that outsourcing portfolio management can improve governance, strengthen risk management, and potentially enhance long-term investment performance while reducing internal administrative burdens.

A Growing Pillar of Goldman Sachs

The latest mandates further cement asset and wealth management as one of Goldman’s most important growth engines. As of March 31, the firm’s outsourced chief investment officer business managed approximately $480 billion in assets. Its broader Asset and Wealth Management division oversees roughly $3.7 trillion, making it one of the world’s largest investment managers and an increasingly important contributor to the bank’s earnings.

Growing this business is central to Chief Executive David Solomon’s plan of making Goldman’s revenue base more balanced and resilient by increasing the share of earnings derived from recurring management fees. The plan has gained added importance as investment banking activity and capital markets revenues have remained susceptible to swings in interest rates, geopolitical uncertainty, and shifting investor sentiment.

What It Means For Verizon And Lockheed Martin

For Verizon and Lockheed Martin, outsourcing larger portions of their retirement assets allows management teams to focus on their core businesses while relying on a specialist investment manager to navigate complex financial markets.

Pension plans and defined-contribution schemes face mounting pressure to generate competitive long-term returns while managing inflation risks, changing demographic profiles and evolving regulatory requirements. Partnering with a global asset manager provides access to dedicated research teams, sophisticated portfolio construction tools, advanced risk analytics and investment opportunities that may not be practical to manage internally.

The mandates therefore represent more than a transfer of investment responsibilities. They illustrate how corporate retirement management is becoming increasingly institutionalized, with companies placing greater emphasis on specialist expertise, scale and operational efficiency.
