During these busy times, investors need to stay on top of the latest profit opportunities, and here is a great place to start. After taking a close look at the latest data on institutional buying pressure and each company’s fundamental health, I decided to revise my Portfolio Grader recommendations for 62 big blue-chip stocks.

Chances are that you have at least one of these blue-chip stocks in your portfolio. So, you may want to give these blue-chip stocks a look and act accordingly.
