Stocks were taking another breather with a slight selling bias on Tuesday morning. As has been observed for close to four years now, the one trend that has remained in place is that investors have lined up and bought stocks literally on every single pullback. 24/7 Wall St. reviews dozens of research reports each morning of the week to find new trading and investing ideas for its readers. Some analyst calls cover stocks to buy, while others cover stocks to sell or avoid.

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

Advanced Micro Devices Inc. (NYSE: AMD) was started as Outperform at Northland Securities, but the $5.00 price target (versus a $2.31 close) had shares up over 2% in early trading. The consensus price target here is only $2.52, and the 52-week range is $2.14 to $4.80.

Apple Inc. (NASDAQ: AAPL) was reiterated Outperform with a $145 price target at Credit Suisse on heels of the WWDC and streaming music. Oppenheimer reiterated an Outperform rating and $155.00 price target. Bank of America Merrill Lynch reiterated it as Buy with a $145 price objective.

Dollar General Corp. (NYSE: DG) was raised to Strong Buy from Market Perform with a $90 price target (versus a $73.34 close) at Raymond James. This is $1 shy of the street’s highest target and compares to a consensus analyst target of $82.70. Dollar General was also relisted as one of our 10 stocks to own for the next decade.

Noble Energy Inc. (NYSE: NBL) was raised to Neutral from Reduce with a $48 price target (versus a $44.69 close) at Nomura. Noble’s consensus analyst target is $53.89, and it has a 52-week trading range of $41.01 to $79.63.

Oracle Corp. (NYSE: ORCL) was started as Hold at Wunderlich. The firm started many software companies (see below), mostly tied to the hot data security market.
