Alphabet's Class A shares (GOOGL) saw a significant increase of 3.6% on Tuesday, part of a wider rally among the 'Magnificent Seven' megacap technology stocks. The surge was fueled by strong investor confidence and anticipation for the wave of earnings reports expected from major tech giants later in the week. This positive market sentiment lifted the entire tech sector, with the NYSE FANG+ Index reaching a new record high during the session. Analysts noted that the upcoming earnings, with Alphabet expected to report on October 29th or 30th, will be a critical test of the ongoing enthusiasm surrounding artificial intelligence and its impact on profitability for these leading companies.
