The second-quarter earnings season is expected to be strong, with the S&P 500 index anticipated to see earnings growth of 5.6% and revenue growth of 4.5%, per the latest Earnings Trends. The stock market is also at record levels. However, the ongoing turmoil in Washington, geopolitical risks, Fed-related uncertainty, and lofty valuation could bring some difficulties for stocks this season (read: Sector ETFs & Stocks to Tap Q2 Earnings Growth).
