Thursday will be a big day for earnings: premarket, General Mills will look to break its streak of bad news, reporting less than street projections for three of the last four quarters. Also coming before the bell is Monsanto, as well as Barnes & Noble: how did a book retailer that has been reporting losses, but beating projections, up nearly 40% in 2014? Plus, Nike on the numbers after the bell, and why Jim Cramer likes 3M's international operations to generate ROI for its investors. He's targeting $160 for the stock. With the end of first quarter earnings, and second quarter numbers looming, the market is looking for positive signs.
