Stocks were higher on Monday, with the Dow Jones Industrial recapturing the 18,000 level again. This marked the 2016 high and also is the first close above 18,000 going back to July 2015.

Investors have decided that the right path is a strategy of buying every dip, as was seen from 2011 to 2015. Now investors are looking for value and undiscovered or overlooked opportunity. 24/7 Wall St. reviews dozens of analyst upgrades, downgrades and initiations each morning from the top brokerage firms. Some of the daily analyst calls cover stocks to buy, and others cover stocks to sell or avoid.
