Top Analyst Upgrades and Downgrades: BHP Billiton, Deere, Logitech, Medtronic, Square, Sealed Air, Orbital ATK and More

Stocks closed marginally lower on Monday, but the markets were looking for direction on Tuesday. Investors seem to have few worries as the Dow, S&P 500 and Nasdaq are all just under all-time highs. The bull market is now well over seven years old and the S&P 500 is valued at 18 times forward earnings. What is amazing is that investors have proven time after time, without fail, that they will buy their favorite stocks in every market sell-off. Those same investors are also on the hunt for new ideas to generate income or gains.

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. Some of these analyst reports cover stocks to buy. Other reports feature stocks to sell or avoid.
