Stocks were indicated to open higher with four Dow Jones industrial average components beating earnings estimates on Tuesday after a very mixed trading session on Monday. With the major market indexes all still up well into the double-digit percentages year to date, the S&P 500 and Nasdaq are still within about 2% of hitting all-time highs again. And that’s happened while the 10-year Treasury yield has crept back up about 20 basis points in less than a month. With so much at stake, investors need to be considering how they want their portfolios positioned for the rest of the year and beyond.
