South Korea’s KOSPI index collapsed 16% in a two-day retail selling frenzy on Monday and Tuesday, capping a record monthly loss of 33% that has erased roughly ₩600 trillion in market value. The panic extended into Wednesday as individual investors — who account for over 60% of daily trading volume on the KOSPI — continued dumping shares, deepening what is already the worst domestic equity rout since the 1997 Asian financial crisis. This is not a garden-variety correction: the speed and emotional force of the selloff reflect a structural vulnerability in Korea’s retail-heavy market, where leveraged margin debt and gamified trading apps turned a modest global headwind into a full-blown local panic. For global investors, the KOSPI collapse serves as a canary in the coal mine — a warning that when retail-driven markets pivot from euphoria to fear, the dislocation can be far faster and deeper than institutional-led selloffs, and the contagion to other emerging markets is now a real risk.

**Meta misses on Q2 earnings, stock tumbles** Meta’s Q2 2026 earnings missed Wall Street consensus by a wide margin, sending shares down as much as 12% in after-hours trading on Wednesday. The miss was driven by a combination of escalating AI infrastructure spending — operating expenses rose 18% year-over-year to $42 billion — and a softening digital-ad market that saw average ad prices drop 4% quarter-over-quarter. This is the first time Meta’s core ad business has shown simultaneous margin pressure and demand weakness, suggesting that the company’s massive bet on generative AI features has not yet produced the revenue lift needed to justify the cost. Investors now face a stark choice: either endorse Meta’s long-term vision at current valuations or demand near-term profitability discipline, and the market’s immediate verdict is clear.
**Sixth person dies in Upper East Side Legionnaires’ disease outbreak** New York City health officials confirmed a sixth fatality from the Upper East Side Legionnaires’ outbreak, with total cases now reaching 90 and six patients still hospitalized as of July 29. The NYC Department of Health has deployed 40 inspectors to sample cooling towers in a 10-block radius, but the source remains unidentified three weeks after the first cases emerged. This is the city’s deadliest Legionella outbreak since 2015, and the delay in pinpointing the reservoir raises serious questions about the adequacy of current inspection protocols and the speed of public-health response in dense urban environments. Residents should avoid window air-conditioning units and report any fever or cough immediately — but the bigger concern is that the same systemic gaps will allow future outbreaks to fester.
