S&P 500 rebound continues

Highlights

- S&P 500 rose 0.26% to 6,661.20, led by Nvidia, AMD, and Micron Technology.

- Technicals show support at 6,587 and resistance near 6,700.

- Investors eye October 1 shutdown risks and Fed outlook.

Nvidia, AMD, and Micron Technology led the gains, reflecting renewed appetite for AI-linked equities after last week’s concerns about debt, energy capacity, and cyclical risks.

Technicals highlight constructive setup

From a technical perspective, the S&P 500 remains comfortably within an ascending channel that has held since early summer. Price action is consolidating near the upper half of the channel, with the 20-day EMA (6,587) and 50-day EMA (6,461) acting as strong dynamic support.

S&P 500 price dynamics (Source: TradingView) The Parabolic SAR at 6,694 indicates overhead resistance, suggesting the index may consolidate before attempting a fresh breakout. As long as the index defends the rising trendline and holds above the 100-day EMA (6,288), bullish momentum remains intact.

Fundamentals balance risk and optimism

Investor sentiment remains cautiously constructive. September is historically a volatile month, yet the index has gained 3.1%, with the Nasdaq advancing over 5%. This resilience reflects confidence in AI-driven earnings potential despite structural challenges. Futures trading ahead of Tuesday’s session showed little change, but the market tone leans optimistic as institutional investors continue to rotate into growth-heavy sectors.

The fundamental backdrop carries risks. The looming October 1 government shutdown deadline could temporarily weigh on sentiment if funding negotiations stall. At the same time, markets remain sensitive to energy costs, with rising demand from AI-related infrastructure placing stress on capacity. However, earnings optimism and reinvestment trends in technology appear to be offsetting these headwinds.

Outlook depends on 6,700 level

In the near term, traders will be watching the 6,700 level as the immediate barrier. A decisive breakout above this threshold would confirm further upside toward 6,800, in line with the channel’s upper boundary. On the downside, any dip below 6,600 could trigger a retest of the 20-day EMA around 6,587, with deeper support seen at 6,460. The structure favors buyers as long as these levels remain intact, suggesting the broader uptrend remains well-supported into the new quarter.

In previous discussions, we noted how the S&P 500’s resilience was being tested against Fed policy uncertainty and shifting inflation expectations. The latest rebound reinforces that view, with AI-linked momentum acting as a key counterweight to macro headwinds. Whether the index extends its climb will depend on how the Fed balances growth and inflation in upcoming data releases.
