The Dow Jones Industrial Average was set to close above 52,000 for the first time on Monday, the same day Google $GOOGL parent Alphabet joined the 30-stock index. Alphabet stock gained more than 4% on its first day as a Dow component.
The Dow was up up about 244 points in mid-afternoon trading, or 0.47%, at 52,120. The S&P 500 rose 0.86% and the Nasdaq $NDAQ advanced 1.49%, with both indexes poised to break five-session losing streaks.
Shares of Comcast $CMCSA surged roughly 7% after the cable and entertainment giant announced plans to split into two separately listed public companies, dividing its media and technology operations. The breakup is slated to take approximately one year to complete.

Oil prices moved higher as traders assessed whether the truce would hold. Brent crude rose to above $74 a barrel and West Texas Intermediate futures advanced to $71.
