Alphabet market cap falls below $4 trillion as shares drop 2.45%

A sub-$4 trillion print is less about the absolute number than about the fragility of the trillion-dollar tier in mega-cap tech, where modest single-day moves can flip a headline valuation. The move is narrow in scope but outsized in symbolism, and it lands on a stock that had already been losing ground since late July. Whether this is a one-day wobble or the start of a deeper re-rating in the largest tech names is the open question worth tracking.
