Reason: Last read's group-wide bounce fully reversed - all four names' RSI fell 4-10 points on negative weekly prints (MU -15.48%, SIMO -20.4%, STX -16.21%, WDC -15.48%), each also posting a single-day drop of -6.9% to -9.4%, and every 30-day print widened deeper into double-digit negative territory.

Tape Read

Last cycle's group-wide bounce — itself framed as a reversal of a prior reversal-lower — has now reversed again, and harder. $MU's RSI fell to 40.5 (was 47.3) on a -15.48% week (was +8.48%), a -8.85% single day inside it, and the 30-day print widened to -28.34% (was -12.15%). $SIMO posted the sharpest reversal of the four: RSI 35.2 (was 45.1), a -20.4% week (was +2.49%), -9.42% single day (the largest in the group), 30D now -33.3% (was -15.78%). $STX and $WDC moved together: $STX's RSI fell to 39.8 (was 48.0, -16.21% 7D, was +8.13%, -8.53% single day, 30D -22.84%) and $WDC's fell to 39.6 (was 45.7, -15.48% 7D, was +8.92%, -6.91% single day, 30D -28.9%, still the deepest 30-day damage of the four). Every name in the group posted a single-day drop between -6.91% and -9.42% within an otherwise negative week, and every 30-day print is now double-digit negative and deeper than last cycle's read.

• $MU — PASS (downgraded from WATCH): RSI 40.5 (down from 47.3), -15.48% 7D — last cycle's bounce off the reversal-lower fully gave back, 30D now -28.34%, the supercycle thesis still flagged intact-but-priced.
• $SIMO — PASS (downgraded): RSI 35.2 (down from 45.1), -20.4% 7D — the sharpest reversal of the four, still hasn't recovered the uptrend regime lost three reads ago.
• $STX — PASS (downgraded): RSI 39.8 (down from 48.0), -16.21% 7D — group-wide reversal, 30D now -22.84%.
• $WDC — PASS (downgraded): RSI 39.6 (down from 45.7), -15.48% 7D — still the deepest 30-day damage in the group at -28.9%.

Lead pick: No add in this complex — the whole group's bounce reversed together and each name posted its worst single-day print of this file's recent run. $MU remains the one to watch given the supercycle thesis stays flagged intact, but nothing here confirms a floor this cycle.
