Here's an interesting sidelight to the current earnings season: The sector showing the most strength, top to bottom, is undoubtedly health care. Among the S&P 500 stocks, 65 percent of the health care companies reported both earnings and revenue that came in higher than the analysts had expected.
None of the other S&P sectors reached even 50 percent by that measure. Consumer discretionary came closest, at 47 percent; technology and financials were close behind, at 46 percent and 45 percent, respectively.
In some sectors, very few stocks exceeded both revenue in earnings expectations. In the consumer staples, energy, industrial and utility sectors, less than a third of all companies met those criteria.
