The Dow Jones Industrial Average extended its record-breaking streak on Friday in a nail-biting end to the day. The blue-chip index turned positive with just seconds to go after spending most of the day sharply lower. 

The Dow was up 0.05%. The S&P 500 added 0.15%, and the Nasdaq gained 0.17%. 

The Dow began its long stretch of records 11 sessions earlier on optimism over a forthcoming tax plan from Donald Trump, reforms that he again touted on Friday.

Trump also promised that he would "massively lower taxes for the middle class."

Treasury Secretary Steven Mnuchin talked tax plans on Thursday, noting that the administration is working to deliver "very significant" tax reform before the August recess in Congress. Mnuchin told CNBC that the plan will focus "on a middle income tax cut and a simplification for business."

HP Enterprise is a holding in Jim Cramer's Action Alerts PLUS Charitable Trust Portfolio.

"Bottom line: HPE's restructuring and refocusing, in addition to its M&A activity, will help drive improved fundamentals beyond 2017, and while we continue to note that sentiment remains foggy until a clearer picture of stand-alone HPE emerges post spin- offs, therein lies the opportunity," wrote Cramer and the AAP team.
