Wall Street makes small gains at the open; Yellen awaited

Yellen will also attend a meeting at 4:30 p.m. ET with other Fed officials. "The markets like it when Janet Yellen speaks and in this case it looks like the weak May jobs number really spooked her. Investors are expecting her to be accommodative and allow the markets to inflate a little bit," said Keith Bliss, senior vice-president at Cuttone & Co in New York.
