Apple unveiled its latest operating system iOS 12 at the conference and even after paring some gains in the afternoon, for a 0.8 percent gain, it still provided the biggest boost to the S&P 500 <.SPX> and helped take the Nasdaq close to its intraday record reached in mid-March.
The technology sector boost added to continued investor optimism after Friday's better-than expected jobs data, according to Kim Forrest, senior portfolio manager at Fort Pitt Capital Group in Pittsburgh.
"On Fridays in the summer, there's not a lot of people behind the desk. These are investors that may not have been around to participate at the end of a holiday week," said Forrest.
Forrest also cited Apple's developer conference and Microsoft's $7.5 billion deal to buy privately held coding website GitHub Inc, which sent its shares up 0.6 percent to a record high.
"Microsoft started its life as a company that provided developer tools. This is the next generation of developer tools. It's good they were able to buy it," she said.
At 2:26 p.m. ET, the Dow Jones Industrial Average <.DJI> rose 162.38 points, or 0.66 percent, to 24,797.59, the S&P 500 <.SPX> gained 11.14 points, or 0.41 percent, to 2,745.76 and the Nasdaq Composite <.IXIC> added 43.22 points, or 0.57 percent, to 7,597.55.
The S&P technology index <.SPLRCT> was up 0.9 percent. Seven of the 11 main S&P indexes were trading higher.
However the Nasdaq Biotechnology Index <.NBI> underperformed the broader market with a 1 percent decline as shares of cancer-focused companies moved after presentations at the ongoing American Society of Clinical Oncology's (ASCO) meeting.

Advancing issues outnumbered declining ones on the NYSE by a 1.58-to-1 ratio; on Nasdaq, a 1.28-to-1 ratio favoured advancers.
The S&P 500 posted 44 new 52-week highs and 5 new lows; the Nasdaq Composite recorded 204 new highs and 37 new lows.
