Alphabet Inc.’s Class A shares climbed to a record intraday high on 28 August 2025, leading major U.S. technology stocks and marking the first all-time peak since the company adopted the Alphabet name. Traders said the move put the stock among the day’s top gainers alongside Amazon. Market participants attributed the advance to expectations that Google will emerge as a key gatekeeper for artificial-intelligence services. Despite the rally, several investors noted that the shares trade at roughly 14 times projected earnings—about half the forward valuation commanded by Nvidia—suggesting room for further upside. Technical analysts added that a recent bullish crossover in the weekly MACD indicator underpins momentum, reinforcing the positive sentiment around the stock.
