24/7 Wall St.

24/7 Wall St. reviews literally dozens and dozens of Wall Street analyst research reports each morning. Some calls are for stocks to buy and some are for stocks to sell. Some may be oriented to value investors and some may be oriented toward day traders. It has been surprising just how many research calls there are when you consider that this week is historically been one of the most quiet weeks each year.

There are several key upgrades that did not make Monday morning’s top analyst upgrades and downgrades.

Take-Two Interactive Software Inc. (NASDAQ: TTWO) is up by less than 1% despite being touted in Barron’s over the weekend. The financial publication showed that more good is coming here and that shares could rise by another 30%. The only point we might make is that video game stocks already are seeing such high gains ahead of the Xbox One and PlayStation 4 that we cannot help but wonder if all the good news has been priced in even before the new consoles hit the retail shelves.

Adobe Systems Inc. (NASDAQ: ADBE) was raised to Outperform from Sector Perform at RBC Capital markets. Barron’s also had a positive spotlight on Adobe, based on three emerging trends in technology that will help it grow beyond boxed software offerings.

Altera Corp. (NASDAQ: ALTR) was raised to Buy from Neutral at Citigroup.

Arkansas Best Corp. (NASDAQ: ABFS) was raised to Strong Buy from Market Perform at Raymond James.

Boise Cascade LLC (NYSE: BCC) was raised to Buy from Neutral at D.A. Davidson.

Embraer S.A. (NYSE: ERJ) was initiated as Outperform at RBC Capital Markets.

Qihoo 360 Technology Co. Ltd. (NYSE: QIHU) was reiterated as Buy, but estimates were raised and the target price was raised to $84 by BofA/Merrill Lynch. Here was our report on Qihoo 360 this morning.

Monday’s top analyst upgrades and downgrades included the following tickers: DDD, SSYS, DLTR, FDO, AMGN, BBY, BIG, DAR, HAS, BTU, RMD, TSN and AMH.
