Reason: The whole complex reversed the stabilization call from last read - SIMO, the one name that had stayed in an uptrend, fell hardest of all four (RSI 57.9 to 41.5, -19% on the week); MU, STX and WDC all resumed sharp weekly declines after briefly flattening.

Tape Read

Last read's "digestion stabilizing" call has fully reversed. SIMO is the sharpest single-name move in the group: RSI collapsed to 41.5 from 57.9 on a -19% weekly decline — it was the one name still trending up two reads ago, and it just joined the rest of the basket in pullback. MU resumed a sharp decline too: RSI 41.1 (was 49.2), -13.31% 7D, -25.12% 30D — the supercycle thesis stays flagged intact-but-priced, but this week's move is a real re-acceleration of the drawdown, not more digestion. STX and WDC both reversed their prior improvement: STX's RSI fell to 42.3 (was 50.8) on a -13.48% week (vs +3.98% last read), and WDC's fell to 39.8 (was 50.0) on a -18.09% week (vs -1.72% last read) — both erasing the stabilization flagged one read ago.

• SIMO — PASS (downgraded from PROMOTE): RSI 41.5 (down sharply from 57.9), now pullback (was the lone uptrend), -19% 7D — the one name still trending just joined the group-wide reversal.
• MU — WATCH (downgraded): RSI 41.1 (down from 49.2), pullback, thesisState: intact-but-priced, -13.31% 7D — the supercycle thesis read is unchanged, but the decline re-accelerated this week.
• STX — PASS (downgraded from WATCH): RSI 42.3 (down from 50.8), -13.48% 7D (was +3.98%) — last read's stabilization fully reversed.
• WDC — PASS (downgraded from WATCH): RSI 39.8 (down from 50.0), -18.09% 7D (was -1.72%) — same reversal as STX, the sharpest weekly print in the group.

Lead pick: No clean add left in this basket this week. SIMO's reversal is the headline: the only name that had avoided the group-wide cooldown just posted the sharpest single-week decline of the four, ending its run as the outlier.
