24/7 Wall St.

February is acting as though it wants to carry on in January’s volatility and downward momentum for stocks. Earnings season also created selective winners and losers. 24/7 Wall St. reviews dozens of Wall Street analyst research reports each morning, looking for new ideas on stocks to buy and stocks to sell. These are this Wednesday’s top analyst upgrades, downgrades and initiations seen from Wall Street research firms.

Arch Coal Inc. (NYSE: ACI) was reiterated as Buy with a $7 price target at Sterne Agee, after the company’s rally even on bad earnings. The firm called it a cyclical value stock. As a reminder, this was featured as one of our own picks of nine stocks that could double in 2014.

Archer Daniels Midland Co. (NYSE: ADM) reported earnings this week, and we have two upgrades seen so far. Citigroup raised its rating to Buy, and Scotia Capital Markets raised the rating to Outperform from Sector Perform.

Citigroup Inc. (NYSE: C) was reiterated as a Sell rating at Argus. The firm believes it remains overvalued in the context of the company’s current challenges, and it believes that and is hoping for a faster wind-down of Citi Holdings. Return on capital also has to improve before Argus thinks buyers will return the stock above tangible book value. Citigroup closed at $46.78, yet the consensus price target is all the way up at $60.53.

Myriad Genetics Inc. (NASDAQ: MYGN) was raised to Market Perform from Underperform at JMP Securities. Keep in mind that shares are up 12% at $30.80 after earnings and after announcing an acquisition. Ladenburg Thalmann downgraded Myriad to Neutral from Buy into the strength.

Sirius XM Holdings Inc. (NASDAQ: SIRI) was downgraded to Hold from Buy at Wunderlich, and the price target was cut to $3.80 from $4.20. Wunderlich was bullish at much lower prices than now. Despite the buyout on the table, the firm believes a strategic investor or convertible offering could come into play.
