#US *US Tech Stocks Slide Across the Board as Red Map Covers Market*
US equities opened lower on May 18, 2026, with a sea of red across the market heatmap as mega-cap tech and chips led the decline.
*Mega-Caps Drag the Market*
The largest losses hit the market’s heaviest weights. *Tesla (TSLA)* fell *2.64%*, the sharpest drop among the Magnificent 7 names visible. *Meta (META)* declined *1.25%*, while *Microsoft (MSFT)* and *Nvidia (NVDA)* slipped *0.84%* and *1.09%* respectively. *Apple (AAPL)* was down *1.15%* and *Broadcom (AVGO)* lost *0.98%*.
Chip stocks also came under pressure. *AMD* dropped *0.87%*, *Micron (MU)* fell *2.61%*, and *Applied Materials (AMAT)* slid *4.53%*. *Lam Research (LRCX)* and *KLA Corp (KLAC)* were down *1.57%* and *2.29%*.
*Broader Weakness Spreads*
The selloff wasn’t limited to tech. *Oracle (ORCL)* dropped *3.54%*, *Cisco (CSCO)* lost *1.32%*, and *Eli Lilly (LLY)* declined *2.14%*. Industrials like *Caterpillar (CAT)* fell *2.72%*, while *GE Vernova (GEV)* slid *4.27%*.
Smaller names saw even steeper drops, with several down over 5%: *SanDisk (SNDK) -5.63%*, *Corning (GLW) -5.25%*, and *NextEra Energy (NEE) -4.52%*. Palantir (PLTR) held up relatively better, down just *0.64%*.
*What’s Behind the Move*
The broad-based decline suggests risk-off sentiment across sectors, with no single group offering shelter. Tech and AI-related names, which led the rally earlier this year, are now seeing profit-taking and rotation out of growth stocks.
With most names in the red, traders are watching whether the pullback deepens or finds buyers at key support levels.
