Philadelphia Semiconductor Index rebound

Highlights

Philadelphia Semiconductor Index (SOX) closed Friday at 11,137 after eight consecutive losses, marking its longest losing streak since 2008.
The index's 9-day Relative Strength Index dropped to 21.5—its lowest since April 2025—indicating oversold conditions that historically precede rebounds.
Key technical resistance is at the 50-day moving average near 12,064, with layered support at 11,110–11,056 and further down at 10,815 and 10,601.

Technical markers point to a possible turn

As reported by Reuters, the Philadelphia Semiconductor Index, or SOX, ended Friday at 11,137 after falling for eight straight sessions, its longest losing streak since October 2008 during the global financial crisis.

Data cited from LSEG show the index has posted a nine-day losing streak only twice since mid-1994, in July 1996 and May 2006. That makes the latest stretch unusually severe by historical standards and raises the likelihood that traders begin positioning for a rebound.

One momentum gauge supporting that view is the 9-day Relative Strength Index, which ended Friday at 21.5. That is its lowest reading since April 8, 2025, when the index closed at the tail end of a tariff-driven selloff, and it indicates oversold conditions that can precede a recovery.

Resistance and support levels in focus

If buyers return, the first resistance level stands near the 50-day moving average around 12,064. Beyond that, the SOX would need to clear the downtrend line from its June peak and move above the October 6 high of 13,350 to bring record highs back into view.

On the downside, support is building in several layers. September lows sit in the 11,110 to 11,056 range, followed by trendline support from the April 2025 low near 10,815 and the rising 200-day moving average near 10,601. The July 2026 low of 10,445 is another level market participants are likely to monitor.

The broader backdrop remains shaped by concerns over elevated borrowing costs and questions about future AI infrastructure spending. Even so, the combination of a prolonged losing streak and deeply oversold momentum readings suggests the sector may be approaching a point where technical buyers step back in.

In our earlier article on Micron Technology’s weakening chart setup, we noted that the stock broke below a rising wedge on the weekly timeframe, a pattern that often signals a rally is losing strength. We also highlighted fading momentum in RSI and MACD, with downside targets mapped to key support zones unless Micron can reclaim the $1,010–$1,030 resistance area on a weekly close.
