While recession fears keep investors on edge, bets over Fed rate cuts in September fuel optimism in the stock market. Additionally, the second-quarter earnings season produced an overall stable picture of corporate profitability but concerns have emerged about the outlook, as estimates for the current period have weakened more than the last two periods.Total second-quarter earnings for 473 S&P 500 members, or 94.6% of the index’s total membership are up 8.0% from the same period last year on 5.0% higher revenues, with 79.7% beating EPS estimates and 59.8% beating revenue estimates. Except for the revenue beat percentage, which at 59.8% is near the lowest for this group of 473 index members over the preceding 20-quarter period, all the other performance metrics are tracking better relative to the recent periods.  Given this, most equity ETFs have impressed with their performance and generated handsome returns over the trailing one-month period. Below are four ETFs from different sectors that have gained from strong earnings despite the market volatility. We have provided a chart for their performances over the past month and compared them with the broader market fund (SPY) and the broader sector. iShares U.S. Medical Devices ETF (IHI – Free Report)iShares U.S. Medical Devices ETF, which provides exposure to U.S. companies that manufacture and distribute medical devices, has gained 6.7% over the past month.
