The tech sector sank early Monday in a broader market sell-off as investors reacted to declines in Chinese stocks.

The Nasdaq Composite Index (RIXF) lost about 23 points, or 1.1%, to 2,005, pummeled by losses in shares of Dell Inc. and Advanced Micro Devices Inc. (AMD).

The Morgan Stanley High Tech 35 Index (MSH) was behind 1.4%, while the Philadelphia Semiconductor Index (SOX) retreated 1.8%.

Aside from AMD, other major chip makers were in the red, including Intel Corp. (INTC), Nvidia Corp. (NVDA) and Texas Instruments (TXN). Early Monday, the Semiconductor Industry Association reported that global chip sales fell 18% year-over-year in July, but were up 5.3% from June.

"The fifth-consecutive month of sequential increases in semiconductor sales reflects improving demand in the consumer sector," SIA President George Scalise said in a prepared statement. .

The Dow Jones Industrial Average (DJI) was down more than 80 points as investors reacted to declines in China's stock market.
