men.industry.co.id - Global stock markets saw record-breaking inflows of $350 billion in July 2026, making it the largest single-month inflow in history. The surge was driven by strong corporate earnings, particularly in the artificial intelligence (AI) sector, and growing investor optimism about the global economic outlook.
However, the rally has not been without turbulence. South Korea's KOSPI index experienced a dramatic crash after more than doubling in the first half of the year, while major investment banks including Goldman Sachs and Morgan Stanley have tempered their return expectations for the remainder of 2026.
S&P 500 Earnings Grow at Fastest Pace Since 2021
Second-quarter earnings for S&P 500 companies grew at their fastest pace since 2021, fueled largely by the AI boom that continues to reshape corporate America. Technology giants reported blockbuster results as enterprise spending on AI infrastructure, cloud computing, and automation accelerated.
Goldman Sachs Research noted that AI is now contributing approximately 0.5 percentage points to US consumer spending through equity wealth effects. The broadening of AI adoption beyond the technology sector into healthcare, financial services, and manufacturing has created new revenue streams and improved profit margins across industries.
The earnings strength has been concentrated in a handful of mega-cap technology stocks, raising concerns about market concentration. The top ten stocks in the S&P 500 now account for a historically high share of the index's total earnings and market capitalization.
Record $350 Billion Inlow in July
Global equity funds attracted a staggering $350 billion in net inflows during July 2026, the largest monthly figure ever recorded. The flood of capital was driven by several factors:
- Strong US corporate earnings beating expectations
- Growing confidence that the Federal Reserve will maintain accommodative monetary policy
- Rotation from money market funds into equities as cash yields decline
- Increasing retail investor participation, particularly in AI-themed investments
The record inflows have provided a strong technical tailwind for equity markets, pushing valuations to elevated levels. The S&P 500's forward price-to-earnings ratio now stands at approximately 22 times, well above the historical average of 16 times.
South Korea's KOSPI Crash: A Cautionary Tale
While US markets have surged, South Korea's stock market has provided a stark reminder of the risks of speculative excess. The KOSPI index more than doubled during the first half of 2026, driven by a combination of government policies encouraging retail participation, regulatory approval of leveraged single-stock ETFs, and a surge in AI-related semiconductor stocks.
The rally proved unsustainable. In August, the KOSPI experienced its sharpest correction in years as leveraged positions were unwound and foreign investors pulled capital from the market. The crash wiped out billions of dollars in market value and left many retail investors nursing significant losses.
The Korean experience highlights the dangers of policy-driven market rallies that are not supported by underlying economic fundamentals. It also underscores the concentration risk inherent in markets that are heavily weighted toward a single sector or theme.
Goldman Sachs and Morgan Stanley: Constructive but Cautious
Two of Wall Street's most influential investment banks have issued their updated market outlooks for the second half of 2026, and the message is one of cautious optimism.
Goldman Sachs Research remains constructive on equities, forecasting continued earnings growth as the AI investment cycle matures. However, the bank expects lower index-level returns than in 2025, as elevated valuations limit further upside. Goldman analysts recommend a more selective approach, focusing on companies that can demonstrate tangible returns on their AI investments.
Morgan Stanley's global research team forecasts global real GDP growth of 3.2 percent in 2026, moderating from 3.5 percent in 2025 before stabilizing and recovering to 3.4 percent in 2027. The bank sees the bull market broadening beyond technology into cyclical and value sectors, but warns that geopolitical risks and trade policy uncertainty could disrupt the positive trajectory.
Implications for Indonesian Investors
The global stock market dynamics have significant implications for investors in Indonesia and Southeast Asia. The Jakarta Composite Index has shown relative resilience compared to some regional peers, supported by steady domestic consumption and commodity export revenues.
However, the concentration of global market gains in US technology stocks raises important questions about portfolio diversification. Investors who are heavily exposed to US mega-cap tech through global equity funds may be taking on more concentration risk than they realize.
Financial advisors recommend maintaining a balanced portfolio that includes exposure to domestic Indonesian equities, regional emerging markets, and a diversified mix of global sectors. The lessons from South Korea's market crash serve as a reminder that chasing momentum without regard to fundamentals can lead to significant losses.
