S&P 500 Edges Up 0.33% as Healthcare Rotation Offsets AI Selloff

Key Takeaways

-The S&P 500 rose 0.33% to close at 7,744.06 on Thursday, supported by healthcare, materials and defensive consumer stocks.

-Eli Lilly gained more than 3%, UnitedHealth rose 2.8% and Walmart added 1.4%, offsetting losses in technology.

-AI-related stocks stayed under pressure: Nvidia fell 1.8%, while Dell and Hewlett Packard Enterprise dropped 6.9% and 7.1%.

-Stronger US CPI and PPI data lifted the probability of a Federal Reserve rate hike by December to 67%.

Traders are watching 7,750.00-7,754.10 as resistance, with 7,747.50 and 7,745.00 as key support levels.

The index has recovered from early losses, though the move reflects a rotation out of technology more than broad buying confidence.

Why Traders Are Watching the S&P 500

The S&P 500 recovered from an early dip on Thursday, 15 October 2026, as investors shifted from AI-related technology stocks into healthcare. Traders are now weighing whether this reflects renewed buying confidence or a move towards safer sectors amid worries about inflation and AI valuations.

Healthcare led the index’s sector gains with a 1.84% rise, followed by materials at 1.71%. Walmart’s advance followed analyst upgrades. Technology continued to struggle, with Nvidia falling despite strong AI demand and Dell and HPE suffering bigger losses.

September’s producer price index posted its strongest increase in four and a half years, following stronger-than-expected consumer inflation. Higher interest rates reduce the present value of expected future earnings, which weighs most on growth-focused technology companies. The Philadelphia Semiconductor Index fell for a seventh consecutive session, and AI infrastructure spending concerns continue to weigh on server manufacturers. Even so, the S&P 500 remains 13% higher year to date, so the broader market has kept most of its earlier gains.

Key factors influencing the index include:

-Inflation data: Hotter CPI and PPI readings reinforce expectations of further rate hikes.

-Treasury yields: Elevated yields place pressure on equity valuations.

-AI sentiment: Concerns over capital expenditure, debt financing and earnings sustainability weigh on tech stocks.

-Sector rotation: Healthcare, staples and materials strength can cushion the index against tech weakness.

Key Trading Levels

The S&P 500 is trading near 7,748.35, with immediate resistance at 7,750.00 and stronger resistance at the reported session high of 7,754.10. A sustained move above 7,750.00 could open the way towards 7,754.10, and increasing volume and an upward-turning nine-period moving average (MA9) could strengthen the breakout signal. The MA9 has recently flattened, suggesting short-term bullish momentum has moderated.

On the downside, 7,747.50 is the nearest support, followed by 7,745.00. A break below 7,745.00 could expose 7,742.50 and 7,739.50, the low of the earlier recovery.

S&P 500 Prediction: Will the Index Rise or Fall?

The index’s next move depends on whether buyers can defend 7,747.50 and push through 7,750.00, or whether sellers return and test 7,745.00.

A bullish scenario could develop if the index holds above 7,747.50 and regains momentum towards 7,750.00, with a sustained break higher targeting 7,754.10. Continued strength in healthcare, staples and materials, or stronger-than-expected revenue from major technology companies, could also support confidence in AI-related stocks.

A bearish scenario could emerge if the index fails at 7,750.00 and falls below 7,747.50, bringing 7,745.00 into focus. A sustained break below that level could extend losses towards 7,742.50-7,739.50. Persistent inflation remains the key downside risk: further data supporting another rate hike could keep yields elevated, while renewed weakness in semiconductors and server makers could add pressure. If selling spreads into healthcare, the index could face a deeper pullback.
