iShares S&P 100 ETF (OEF) analysis, October 10, 2025

Published October 10, 2025 · OEF chart, levels and live analysis

Key Updates

The iShares S&P 100 ETF has pulled back 2.13% since the last report to $326.83, breaking the uptrend that had been in place since early September. Despite the short-term correction, the ETF is still up 0.41% on the month, pointing to relative resilience among the largest U.S. companies in the current market environment.

Current Trend

The ETF is in a short-term pullback after touching levels above $333 in late September. A five-day decline of 2.14% and a one-day drop of 2.80% show selling pressure is building. But the positive monthly move (+0.41%) suggests the longer-term uptrend is still intact, and the current move may be a technical correction.

Investment Thesis

The thesis rests on the strength of the largest U.S. companies in the S&P 100 and their ability to generate steady cash flows while the Fed keeps policy loose. The rate cut that started in September creates a favorable backdrop for asset valuations and corporate growth.

Thesis Status

The thesis still holds despite the short-term pullback. The current decline likely reflects profit-taking after a strong September run rather than a fundamental shift in the appeal of large U.S. companies. The positive monthly performance confirms the underlying drivers remain solid.

Key Drivers

The main driver for the ETF remains record inflows into U.S. funds, which hit $142 billion in September 2024 — the best monthly figure of the year. Year-to-date inflows have reached $927 billion, showing sustained investor demand for U.S. assets. Source: Morningstar

Technical Picture

The ETF is trading at $326.83 after pulling back from September highs above $333. Key support sits around $320, where the ETF traded in early September. A break below that level could open the door to a move toward $315. Resistance has formed in the $330–333 zone, where sellers have been active.
