Good morning. The Nasdaq and S&P 500 opened in the red as chip stocks came under pressure and investors awaited a new sanction campaign against Iran and a breakdown in US-Canada trade talks.

Here's a check of the markets in the first few minutes of trading, based on a heat map powered by Yahoo Finance AlphaSpace data.

Tech (XLK) stocks led the S&P 500 (^GSPC) lower, echoing declines in Asian markets overnight. Memory chip makers Sandisk (SNDK) and Micron (MU) saw sharp drops following rumors over the weekend that the Trump administration could allow Apple (AAPL) to source chips from China's CXMT.

Consumer staples stocks (XLP) were the best performers in early trading.

Here are some notable stocks that Yahoo Finance readers are viewing this morning: SpaceX (SPCX), Sandisk (SNDK), Alibaba (BABA), Marvell (MRVL), SK Hynix (SKHY), Applied Optoelectronics (AAOI), and Lam Research (LRCX).
