The market went through some gyrations on Wednesday in reaction to Fed Chairman Bernanke’s testimony before the Joint Economic Committee. He first defended continued quant easing by warning, “A premature tightening of monetary policy could lead interest rates to rise temporarily but also would carry a substantial risk of slowing or ending the economic recovery.” Stocks dutifully rallied and all major indexes hit new intraday highs.

The S&P 500 is up 14.5% year-to-date through Wednesday, and the defensive sectors like healthcare, consumer staples, and utilities have done even better. But so far in May, the leaders have been industrials, consumer discretionary, energy, materials, financial, and technology.
