Sluymer's view: Holding 50–62% retr.; resistance 957, then 1145: “STX’s consolidation above key support at its 50-62% retracement continues with 957 followed by 1145 next resistance.” (Chartbook, Sep 29, 2026).
Watch this week: Fri Nov 6: breakout entry on a close above $702.89 (+15.9%); a Friday close below $111.91 (-81.5%) invalidates.

Notes & caveats

Duquesne Family Office (13F) holding, entry card (treated like the US Watchlist). Holdings: SEC 13F-HR for the quarter ended Tue, Jun 30, 2026, filed Fri, Aug 14, 2026 (SEC EDGAR 13F-HR 0001536411-26-000006 (period 2026-06-30, filed 2026-08-14); https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=1536411&type=13F); weight 2.26% of the reported 13F portfolio value (incl. option lines). Benchmarks: S&P 500 (20 pts) and XLK (10 pts). Trading items and bands use the Tue, Nov 3, 2026 close; trend uses the Fri, Oct 30 week. Entry levels: Buy Zone = breakout retest zone (BUY names only: from the broken level down to the floor of the resistance band it came from, or level −2%, whichever is tighter; a weekly close below = failed breakout); Breakout Buy Level = top of R1; Trend Breakdown (invalidation) = S2 floor on a Friday close; Profit-Taking = next resistance band above the breakout. Verdict: AVOID = Trend Down (confirmed on two Fridays) or Friday close below a falling 40-wk SMA; BUY = a weekly close above a Breakout Buy Level fixed from the prior week's data with ≥2 tools within 3% (most recent such breakout in the last 4 weeks), every Friday close since and the latest close still at or above it, and Trend not Down; WAIT = otherwise. Buy Zone is reference only. Coppock = 10-bar WMA of ROC(14)+ROC(11), standard settings used as a placeholder because his are unpublished; DAS is omitted. Zone = sign + 3-yr percentile; direction = 2 bars. SMAs are simple; swings are 5-bar extremes; the channel is a 2-yr log regression ±2σ. The breadth proxy is the % of 500 current S&P 500 members with a rising weekly Coppock; it has survivorship bias, is a regime input only, and no other stock was scored. Weights are our choices (playbook §10); the state rule matched 86% / 83% of his sector states in-sample. Data: Yahoo Finance (unadjusted); weight from the Portfolio Dashboard (PIM 11/2 EOD, read-only).
