Markets Close in the Red on Last Trading Day of May

It was the last day of trading for the month of May and the markets closed the day in the red, but are higher for the second month in a row. This was the second down week in a row for the Dow Industrial Average. It's the first back-to-back weekly loss in more than two months. The S&P 500 and Russell 2000 snapped a 3-week winning streak, while the NASDAQ snapped a 2-week winning streak.

The Dow Transports are down for a third straight month, its longest losing streak in more than two-and-a-half years.

All 10 S&P sectors closed today and this week lower, which hasn't happened in months. The declines this week were led by energy, industrials and financials.

But it was an overall mixed picture for the S&P sectors this month, with the big winners being health care, technology and financials.

We are getting a lot of big economic data next week. Monday we will be getting the ISM Manufacturing Index, with the Non-Manufacturing Index being released on Wednesday. And we get May jobs numbers out on Friday.
