Stocks were pounded lower on Friday but were indicated up marginally Monday morning as bargain hunters are looking for oversold opportunities. While 2015 and the year-end trading have both proven to be quite choppy, the fiscal reality is that investors have bought every single market pullback in the past four years. 24/7 Wall St. reviews dozens of analyst research reports each day of the week. The aim is to find new investing and trading ideas for our readers. Some analyst reports cover stocks to buy. Other such reports cover stocks to sell or avoid.

These are this Monday’s top analyst upgrades, downgrades and initiations.
