iShares PHLX SOX Semiconductor (SOXX)

Executive Summary

SOXX has declined 2.32% since the August 28 report, falling from $508.69 to $496.88, breaking below the $500 psychological level and the tentative support zone near $506 where Michael Burry had last increased his short position. The ETF remains up 64.99% year-to-date despite a 21% drawdown from its highs, with the latest price action signaling intensifying bearish momentum as the semiconductor complex continues to unwind prior overvaluation extremes.

Key Updates

Since the previous report dated August 28, SOXX has dropped an additional 2.32% to close at $496.88, extending the losing streak to four out of the last five reporting periods. The ETF has now fallen below the $506 level where Michael Burry added to his short position on July 30, invalidating the tentative support that had formed near his disclosed entry points. On a 1-month basis, the fund is down 1.59%, while the 5-day decline of 3.34% and 1-day drop of 2.77% indicate accelerating near-term selling pressure. The 6-month return remains elevated at +41.04%, reflecting the magnitude of the prior rally now being retraced.

Current Trend

The primary trend remains lower following the breakdown from the July peak. YTD performance of +64.99% confirms the long-term uptrend from the start of 2026 is intact in absolute terms, but the trajectory has shifted decisively negative since late July. The ETF has shed approximately 21% from the $643 area where Burry initiated his short, and the failure to hold $506 removes a near-term floor. Resistance is now expected at the prior support zone of $506–$508, with the next psychological barrier at $519.40 (the August 27 rebound high). Support is untested below $496.88, with Burry’s March 2027 put strike prices in the low-to-mid $400s indicating potential downside targets if bearish momentum persists.

Investment Thesis

The investment thesis is increasingly challenged. The prior thesis that SOXX could stabilize near Burry’s disclosed short entries ($536 and $506) has been invalidated by the break below $500. Market-wide factors—specifically extreme historical overvaluation in the Philadelphia Semiconductor Index (P/S ratio exceeding 16 and 200-day moving average premium at the highest level since 2000)—continue to dominate price action. Company-specific demand drivers within the SOXX constituents are not detailed in the current data set, leaving the macro de-rating narrative as the primary fundamental vector. The risk profile has tilted further toward downside continuation as systematic liquidations appear to outweigh dip-buying demand.

Thesis Status

The status has deteriorated from cautiously bearish/tentative support to actively bearish. The August 27–28 rebound to $519.40 has been fully reversed and exceeded to the downside. The inability to sustain prices above Burry’s July 30 short entry (~$506) suggests that either Burry has added further downside pressure or market participants are front-running his thesis. The prior expectation of a tradable base near $506 is no longer valid; the ETF is now in open territory with no defined support from the provided data until the low-to-mid $400s referenced by Burry’s put strikes.

Key Drivers

The dominant driver remains Michael Burry’s disclosed bearish positioning and the associated valuation reset in semiconductor equities. Per Business Insider, Burry shorted SOXX at approximately $643, increased his position near $536 and again near $506, and rolled put options to March 2027 with strikes in the low-to-mid $400s. His cited rationale—P/S ratio above 16 and 200-day moving average premium at the highest level since 2000—provides a fundamental anchor for the bear camp. The VanEck Semiconductor ETF (SMH) recorded its worst July performance in 30 years, underscoring broad-sector liquidation. No bullish fundamental catalysts were present in the provided news flow to counter this narrative.

Technical Analysis

Price action is bearish across all near-term time frames. The 1-day decline of 2.77% and 5-day decline of 3.34% confirm accelerating selling. The break below $500 and the prior $506 support level opens the door for a test of lower levels. Resistance now sits at $506–$508 and $519.40. The 6-month gain of 41.04% and YTD gain of 64.99% indicate that despite the recent drawdown, the ETF remains technically extended from its 2026 starting base, leaving room for further mean reversion. Volume characteristics are not provided, but the velocity of the decline suggests institutional distribution.

Bull Case

• SOXX has already declined approximately 21% from the $643 peak and trades below Burry’s most recent disclosed short entry near $506, implying a significant portion of the initial de-rating has already occurred. Source
• The ETF maintains a robust year-to-date return of +64.99%, indicating that underlying semiconductor demand fundamentals delivered strong earnings power in the first half of 2026 before the current correction. Source
• Burry’s rolled put options target the low-to-mid $400s by March 2027, establishing a defined downside threshold that may attract value-oriented capital if prices approach that zone over an extended horizon. Source
• The current price of $496.88 represents a fresh discount to the $519.40 rebound high registered on August 27, potentially improving risk-reward for long-term entrants relative to levels seen just one week prior. Source
• Previous analysis had identified tentative support near Burry’s disclosed levels; while $506 has broken, the velocity of the decline may set up a reflexive oversold bounce as short-term momentum becomes stretched. Source

Bear Case

• The Philadelphia Semiconductor Index’s price-to-sales ratio exceeded 16 and its premium to the 200-day moving average reached the highest level since 2000, supporting a prolonged valuation-driven bear market. Source
• Michael Burry has demonstrated conviction by scaling into his SOXX short at successively lower prices ($643, $536, and ~$506) and rolling puts to March 2027, signaling expectation of further downside rather than a quick reversal. Source
• The VanEck Semiconductor ETF (SMH) posted its worst July performance in 30 years, confirming broad-based institutional liquidation across the semiconductor complex beyond SOXX alone. Source
• SOXX has broken the tentative support zone near $506 where Burry added shorts, invalidating the August stabilization thesis and opening a path toward the low-to-mid $400s strike prices implied by his updated put positions. Source
• Near-term momentum is accelerating to the downside with a 5-day decline of 3.34% and 1-day decline of 2.77%, indicating that selling pressure is intensifying rather than abating as the ETF undercuts prior lows. Source
