Alphabet's stock fell 2.2% as analysts highlighted that the company's second-quarter earnings, which seemingly beat expectations, were significantly boosted by a $77.1 billion unrealized gain from equity investments. While GAAP accounting rules require these gains to be included, analysts suggest investors should discount this figure when assessing the company's underlying business growth, as such gains are volatile and not directly tied to core operations. Alphabet itself has cautioned that fluctuations in investment values could significantly contribute to the volatility of future income.
