The tech-heavy Nasdaq Composite led Wall Street with a 1.11% advance, gaining 290.85 points to close at 26,430.89 on Oct 19, Reuters reported. The session marked a rebound for the chip sector and artificial intelligence-related stocks following last week’s bruising selloff.
Semiconductor Index Snaps Longest Losing Streak Since October 2008
The Philadelphia Semiconductor Index closed up 1.6% to snap an eight-day losing streak. During that slide, the index fell about 15.7% for its longest run of declines since October 2008, according to Reuters. Michael James, managing director and equity sales trader at Rosenblatt Securities in Los Angeles, noted that market sentiment had grown excessively negative. “Rubber bands can only stretch so far in one direction before they snap and start reversing, and you finally saw that enough-is-enough moment in the semiconductors after Friday’s close,” James said.
James added that nothing fundamentally changed between Friday’s close and Monday’s open beyond the absence of negative weekend news. With upcoming technology earnings reports approaching, he cautioned that the market remains far from out of the woods. On Oct 16, the S&P 500 and the Nasdaq had recorded their largest weekly declines since late June. Investor unease has centered on how costly AI developments will be financed, alongside worries that higher interest rates might curb infrastructure investments.
Mixed Index Closes and Sector Divergence Across Wall Street
While the Nasdaq advanced 1.11% and the S&P 500 gained 31.29 points, or 0.41%, to finish at 7,690.73, the Dow Jones Industrial Average dropped 36.38 points, or 0.07%, to 51,966.03, Reuters reported. Across the S&P 500’s 11 major industry sectors, seven closed lower. Consumer discretionary led the advancers with a 2.7% gain, supported by Amazon.com shares rising 5% after Morgan Stanley named the company its top pick. Tesla added a 3.8% advance to provide the sector’s second-biggest index point boost.
Conversely, defensive utilities fell 2% and real estate lost 1.2% as the session’s biggest laggards. Energy markets also trimmed earlier support as oil prices fluctuated. US crude oil futures settled up 2.2% at $103.66 a barrel following attacks by Yemen’s Iran-aligned Houthis on a Yemeni military training camp and renewed strikes on Saudi energy, airport, and military facilities, as noted by Reuters.
Corporate Upgrades and Profit Surprises Shape Individual Stocks
CoreWeave traded down 0.4% after erasing early gains that followed an upgrade by Goldman Sachs to “buy” from “neutral.” The cloud computing provider had been at the center of the previous week’s selloff due to investor concerns over a $50 billion debt load. CoreWeave peers outperformed during the session, with Nebius adding 2.9% and Iren advancing 2.7%, according to Reuters.
Elsewhere, Intel shares rallied 2.4% after J.P. Morgan upgraded the stock to “neutral” from “underweight.” Steelmaker Cleveland-Cliffs saw its shares surge 16% after reporting a third-quarter profit that surpassed analysts’ estimates.
