Illinois-based Abbott Laboratories ABT is scheduled to report second-quarter results before the opening bell on Jul 20. The company has a diversified portfolio that was reshaped through strategic acquisitions/divestitures in recent times. Abbott Labs has an impressive track record so far, having surpassed estimates in each of the four trailing quarters with an average earnings surprise of 3.17%. Strengthening of the dollar against almost every other currency has been denting the company's performance over the past few quarters.
