Stocks are looking for direction after the European Central Bank decision. Investors are being conditioned almost daily by the financial media that the bull market has now turned into a stock picker’s market. 24/7 Wall St. reviews dozens of analyst research reports each morning of the week, hunting for new ideas and hidden gems for our readers. Some of these analyst calls are about stocks to buy, but some of the research reports cover stocks to sell or to avoid.

These are this Thursday’s top Wall Street analyst upgrades, downgrades and initiations.

Apple Inc. (NASDAQ: AAPL) was reiterated as Outperform and the price target was raised to $685 from $610 at BMO Capital Markets. Just this week we noted that there have been almost 10 analyst price target hikes now.

Bankrate Inc. (NYSE: RATE) was raised to Outperform from Sector Perform with a $21 price target at RBC Capital Markets.

BHP Billiton Ltd. (NYSE: BHP) was downgraded to Sector Perform from Outperform at RBC Capital Markets.

Broadcom Corp. (NASDAQ: BRCM) was raised to Equal Weight from Underweight by Barclays.

Bristol-Myers Squibb Co. (NYSE: BMY) is being reiterated as Outperform with a $59 price target (versus a $46.59 close) at Credit Suisse. The firm believes that the street is being too negative on the company and a call with physicians leads it to think that the company’s lung cancer study design is not as hazardous as the negativity has been.
