U.S. equities extended their advance this week as several of the market’s most valuable technology and financial companies climbed to fresh all-time highs, underscoring investors’ growing risk appetite. Microsoft — the world’s second-largest listed company — Broadcom, Netflix and Palantir each set intraday records on 25 June. The momentum broadened on 26 June, when Nvidia joined Microsoft at new peaks while JPMorgan Chase, Goldman Sachs, Coinbase, Spotify and CrowdStrike also closed at historic highs. JPMorgan’s breakthrough is notable because bank shares typically lag in the early stages of market rebounds; Axios said the move could help confirm that the rally has matured into a broader bull phase reaching beyond technology. Activity remained intense in smaller, high-volatility names. Cyngn jumped 258% and Vor Biopharma climbed 71%, while Nvidia added about 1.1% among the day’s most-traded tickers. Micron Technology slipped 1.8% and Altimmune plunged 56%.
