Stocks were jumping higher yet again, on the heels of Thursday’s “telegraph of more quantitative easing” from the European Central Bank and from very strong earnings out of the tech giants. Yet again, investors are proving that they have an appetite to buy the top stocks either on weakness or when there is value. 24/7 Wall St. reviews dozens of analyst research reports each morning of the week to find new investing and trading ideas for our readers. Some of these analyst calls cover stocks to buy and other calls cover stocks to sell or avoid.

These are this Friday’s top analyst upgrades, downgrades and initiations.

AbbVie Inc. (NYSE: ABBV) was defended at Jefferies on the recent hepatitis C FDA advisory weakness, with a reiterated Buy rating and $85 price target. AbbVie shares closed Thursday down 10.3% at $48.27, against a 52-week range of $45.45 to $71.60.
