Stocks end near lows, Dow skids over 150 as Syria fears escalate; Vix spikes 12%
Stocks finished sharply lower for a second session Tuesday, with the Dow falling to a two-month low, amid escalating worries over potential U.S. military action in Syria.
Defense Secretary Chuck Hagel told the BBC the U.S. military is "ready to go" if President Barack Obama orders action over a chemical weapons attack in Syria.
Meanwhile, NBC News reported the U.S. could launch a missile strike against Syria "as early as Thursday."

"I know some people are dismissing it as an excuse for a market that was looking to go down, but I think if you look at things like the spread between Brent and West Texas beginning to spread out, that tells you there is some real concern," he said.

Oil prices settled above $109 a barrel, its best one-day gain of the year, amid worries that potential military action in the Middle East could disrupt oil production.
And Treasury prices gained. The benchmark 10-year Treasury yield eased to to 2.76 percent from 2.79 percent late Monday. Separately, the Treasury auctioned $24 billion in 2-year notes at a high yield of 0.386 percent. The bid-to-cover ratio, an indicator of demand, was 3.21, versus a recent average of 3.48.
On Monday, U.S. Secretary of State John Kerry said he believed Syria had used chemical weapons on its own people, and that the Syrian government must be held to account.
"I think [the Fed] desperately would love to taper but it's going to be difficult at this point for Mr. Bernanke to keep a straight face and say that this is a data-driven decision," said Cashin. "So far, the data's been lousy and unless he gets a miracle with the non-farm payrolls, I think it's going to be tough to justify tapering."

Investors seem to be protecting more against a downside move, he said.
