1. Employment data is 'scary good', rate cut expectations shattered: May's new job additions doubled, showcasing an exceptionally strong labor market. This means inflation is hard to bring down, and the Fed not only lacks a reason to cut rates but might even be forced to hike them. High rate expectations slammed growth tech stocks that rely on future cash flow.

2. US Treasury yields are skyrocketing: As soon as the data dropped, the 10-year Treasury yield shot up to around 4.53%, with the 30-year breaching 5%. With risk-free rates this high, overvalued tech stocks instantly lost their appeal.

3. Chip giant's conservative guidance sparks a sell-off: Broadcom's AI revenue surged by 140%, but due to next quarter's guidance falling short of Wall Street expectations and hinting at clients bringing in competitive suppliers, the stock plummeted over 12% after hours. This shows that being merely 'great' in AI chip stocks isn't enough; they need to be 'perfect' to hold their prices. This sentiment directly crashed the global semiconductor sector (KOSPI dropped 5.5% in a single day).

4. Tech giants in a funding frenzy, AI 'burn rate' anxiety spreads: Google announced its largest equity financing since going public to expand AI computing power. This has raised market alarms: the pace of AI infrastructure spending is far exceeding expectations, aggressively draining resources in the short term, and the ROI is starting to face skepticism from Wall Street.

5. Epic IPO incoming, market funds moving early: SpaceX is set to launch a record-sized IPO next week, with two more AI super unicorns waiting in the wings for the second half. To prep for these behemoths, institutional funds have started to offload existing tech stocks to reposition, creating a notable 'bloodletting effect'.

6. New Fed chair's debut, policy suspense at peak: Next week, Warsh will hold his first rate-setting meeting since taking office. Faced with strong employment and high inflation, if he isn't hawkish enough, the bond market might take matters into its own hands to push rates higher; conversely, if he leans hawkish, the stock market will also take a hit.

7. Retail data crash, consumer worries emerge: Lululemon significantly cut its full-year outlook, plummeting over 10% after hours. This reveals a harsh truth: high inflation and soaring oil prices are seriously biting into North American consumers' purchasing power.

8. Valuation in a dangerously extreme 'vacuum zone': The market cap-to-GDP ratio of U.S. stocks has hit a historical high, with several indicators nearing the levels of the 2000 internet bubble. At such elevated valuations, the market's tolerance for any negative news is virtually zero.
