Stocks were indicated to open marginally higher on Monday despite a global hack spreading. The major market indexes are all within striking distance of all-time highs. It is also important to consider that this bull market is now more than eight years old and investors have bought every single pullback. Those same investors are also looking for new trading and investing ideas.

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

These were the top analyst upgrades, downgrades and other research calls from Monday, May 15, 2017.
