Not all earnings news is good news -- Oracle shares are down more than six percent as we get ready for Friday morning's open, after the company disappointed with its results. However, with shares around the $40 mark, Jim Cramer says it's time to buy in, and he's targeting hardware sales increases and a big boost in Oracle's cloud division as a catalyst. It's a busy Friday morning for earnings, Darden Restaurants looks to fend off activist investors who want to break it up, but it will have to do better than missing three out of the last four quarters. Plus, we'll get earnings from Carmax, as well.
