Art Cashin Video: What I'll be watching next week

Art Cashin says he expects bonds and yields to remain a big factor for stocks next week as the Federal Reserve holds its annual summit in Jackson Hole, Wyo., even though Ben Bernanke won't attend.

Cashin, UBS' director of floor operations at the NYSE, told CNBC's Bob Pisani at midday that 2.8 percent will remain the key level to watch for the U.S. 10-year note.

"Yesterday when we got above 2.8, bids got canceled all across the floor and only returned slightly after we slipped back the other way."
