24/7 Wall St.

Stocks have been hitting new all-time highs, and Tuesday’s opening bell was indicated to open higher. Stocks are valued at about 18 times forward earnings on the S&P 500 Index, but investors are still looking for ways to make money via dividends, overlooked opportunities, value and more. Those same investors have proven over and over, for about six years, that they will buy stocks on every pullback.

24/7 Wall St. reviews dozens of analyst research reports each morning of the week. The goal is to find new investing and trading ideas for its readers. Some analyst reports cover stocks to buy. Other reports feature stocks to sell or avoid.

These are the top analyst upgrades, downgrades and initiations seen on Tuesday morning:

Ford Motor Co. (NYSE: F) was started as Underperform with a $10 price target (versus a $12.18 prior close) at Jefferies. The stock has a 52-week trading range of $10.44 to $15.84 and a consensus analyst price target of $13.53.
