March 10 (Reuters) - The Nasdaq led a selloff among Wall

Street's main indexes on Monday, falling nearly 4% to a near

six-month low, on fears that a tit-for-tat tariff war could

spark an economic slowdown.

Technology stocks such as Nvidia ( NVDA ), Apple ( AAPL )

and Microsoft ( MSFT ) fell between 3% and 5% and were the

biggest drags on the index.

CBOE's volatility index, also known as Wall Street's

fear gauge, rose over 3.12 points to 13 points - its highest

since December 18.

At 11:05 a.m. ET the Dow Jones Industrial Average

fell 323.95 points, or 0.76%, to 42,477.77, the S&P 500

lost 114.16 points, or 1.99%, to 5,656.04, and the Nasdaq

Composite lost 665.79 points, or 3.66%, to 17,530.43.
