Global signal: Sharply rising Treasury yields rattle Wall Street

Sharply rising Treasury yields rattled Wall Street Wednesday, weighing down stock indexes at the start of another month in what's been a turbulent year.

The 10-year yield is back at 2.91 percent, still behind the recent high of 3.2 percent.

Stocks began their slide immediately after the release of several reports on the US economy, including one showing manufacturing growth was stronger last month than expected.
