Stocks were firm again on Wednesday morning. Investors have now formally proven that they are willing to buy value and overlooked stocks on the dips. 24/7 Wall St. reviews dozens of analyst reports each morning to hunt for new investment and trading ideas for our readers. Some of these key analyst reports cover stocks to buy, while others cover stocks to sell or to avoid.

These are this Wednesday’s top analyst upgrades and downgrades featured by 24/7 Wall St.

Cree Inc. (NASDAQ: CREE) was indicated down well over 10% after disappointing earnings. The LED company was downgraded to Hold from Buy and the price target was slashed to $29 from $41 at Canaccord Genuity.

Coca-Cola Co. (NYSE: KO) saw a 6% drop after earnings and guidance showed more woes for sugar-water drinks. The beverage giant was downgraded to Sell from Hold and the price target was set at $37.50 (versus a $40.68 close) at Soc-Gen.

Ocwen Financial Corp. (NYSE: OCN) was downgraded to Hold from Buy at Evercore on the heels of its New York state investigation into backdating foreclosure and loan-modification letters. Merrill Lynch also downgraded the stock to Neutral from Buy and slashed the price target to $23 from $35.

3D Systems Corp. (NYSE: DDD) was started as Outperform with a $57 price target (versus a $43.38 close) at Oppenheimer. The timing of this call was ahead of 3D’s earnings warning that has taken shares down 8% or so, but most investors will now be looking at the call versus the warning.

Yahoo! Inc. (NASDAQ: YHOO) was raised to Outperform from Market Perform and the price target was raised to $50 from $40 at FBR Capital Markets. This was also one of the five top earnings winners that had carryover into Wednesday.
