Microsoft (MSFT) surged to add a record $490 billion to its market capitalization in a single trading session, acting as the primary catalyst for a sharp reversal across US equity markets.
The historic valuation expansion helped erase losses accumulated earlier in the week, signaling a decisive shift in investor sentiment toward large-cap technology stocks.
The rally was broad-based, with US indices staging a strong comeback as capital flowed back into risk assets.
The momentum extended to European markets, where the Dutch AEX index sharpened its record high, reflecting the spillover effect of Microsoft’s performance on global equity benchmarks.
Traders viewed the move as a validation of the tech sector’s resilience amid broader macroeconomic uncertainty.
This development follows Microsoft’s better-than-expected earnings report, which provided the initial spark for the rally.
