More volatility as has been the trend for some time now with the Dow down about 200, then back to even, then up around 200 then down again to close up 97. It was another day of running from tech and towards the value and defensive stocks that benefit from an expanding economy. There have been wobbles over mostly unfounded inflation concerns but private payrolls increased in April and jitters continue to be reflected as volume is again below average at 8.3 billion.

The Dow Jones Industrial Average ended at a record high on Wednesday, while Nasdaq gave up its earlier gains and closed in red.  Energy (.SPNY) and materials (.SPLRCM) continued this week's momentum, leading gains among S&P 500 sectors.Defensive utilities (.SPLRCU) and real estate (.SPLRCR) led sectoral declines.

Strong economic data and earnings pushed the S&P 500 and Nasdaq indexes to record high last week, but markets have wobbled amid concerns about rising inflation and potentially higher U.S. interest rates.  "Once you have markets hitting the highs we have seen recently, the one thing investors are worried about is rising inflation and what that means for profitability of companies," said Shawn Cruz, senior market strategist at TD Ameritrade.  Tech sell-off accelerated on Tuesday after Treasury Secretary Janet Yellen suggested that interest rates might need to rise in an overheating economy.  She later clarified that a near-term interest rate hike was not something she was "predicting or recommending" on Tuesday evening.
