The stock market's rally has been fueled by optimism over economic resilience and strong earnings, with 86% of S&P 500 companies beating earnings expectations, according to FactSet. However, risks remain, including seasonal market weakness from August to October and uncertainties surrounding the U.S.-Iran conflict. Additionally, some analysts warn that bullish sentiment may be overextended, potentially leading to a market correction. Historical data from Bank of America suggests that extreme bullish sentiment often precedes market downturns, with potential drawdowns of 2%-3% in the following months.
