A great university, but an even better stock. Why? American Public University System (APUS), wholly owned by American Public Education, Inc. (APEI), makes a strong case for leadership in its segment by providing online programs to address critical challenges in higher education. As America faces the dual challenges of reining in crippling tuition costs while significantly increasing the number of college graduates receiving a quality education, APUS has found a business model that seems to accomplish both goals.

Here are some highlights from this past week's earnings coverage on BloggingStocks:

• American Public Education Inc. (APEI) received an analyst upgrade following the Q4 report and guidance.
• Autodesk Inc. (ADSK) traded higher after it reported swinging to a profit in Q4, but revenue declined year over year.
• Blackstone Group (BX) reported adjusted Q4 earnings, compared to a year-ago loss, and postive renvenue too.
• Campbell Soup Co. (CPB) higher Q2 earnings beat estimates, but shares fell on so-so revenue results.
• DreamWorks Animation SKG Inc. (DWA) lower Q4 earnings beat expectations but net income for the full year rose.
• Garmin Ltd. (GRMN) topped analysts' Q4 earnings expectations but shares fell after it warned of lower margins.
