Apple Overtakes Nvidia as World’s Most Valuable Company β Apple held steady with a $4.8 trillion market cap, surpassing Nvidia. Investors are reassessing the AI thesis, reshuffling the tech leadership rankings.
SpaceX Market Cap Evaporates ~$1 Trillion β Shares fell 38% from peak, shedding roughly $1 trillion in market value from all-time highs, down as much as 4.6% to $125.13 intraday.
Iran Threatens Total Oil Export Blockade β Iran stated that as long as US aggression continues, not a single drop of oil or gas will pass through the region.

π§ Analysis
Market fear has intensified markedly, with semiconductors bearing the brunt of the sell-off β the Philadelphia Semiconductor Index’s 5%+ single-day drop signals classic AI bubble deflation trading.
Apple overtaking Nvidia marks a market repricing of the AI narrative β no longer the “everything is AI” euphoria phase, but a rotation toward earnings certainty and cash flow.
Crude oil’s 2.8% surge reflects genuine supply disruption risk. Iran’s threat to fully blockade the Persian Gulf is no longer mere rhetoric; combined with Ukraine’s strikes on Russian refineries and oil tankers, the global energy supply chain faces multi-point stress.
Gold oscillates around the $4,000 threshold, supported by safe-haven demand but pressured by high-level profit-taking. Without substantive de-escalation in the US-Iran situation, the gold price floor will continue to rise.
US corporate executives cashed out $77.6 billion in H1, the second-largest wave of insider selling in nearly 20 years β coupled with the Philadelphia Semi Index’s 19% retreat from highs, insider signals warrant caution.
The consumer sentiment reading is imminent; if data weakens further, it will reinforce the “stagflation” narrative, dealing a double blow to risk assets.
