Reason: AMZN posted a +15.32% single-day earnings pop and a +17% week, closing to just -2.51% off a 52-week high; MRVL and ARM both decelerated out of last read's fresh new lows without recovering the drawdown; NVDA's pullback eased slightly; TSM stabilized; PLTR held roughly flat.

Tape Read

$AMZN is the story this cycle: a +15.32% single day inside a +17% week put RSI at 67.7 (up from 36.3), 30D +12.36%, and now just -2.51% off its 52-week high (was -17.12%) — last read's "steadiest name broke" call has fully reversed on an earnings-driven surge, still golden-cross and thesis flagged intact. $MRVL and $ARM both decelerated out of last cycle's fresh new lows without recovering the ground lost: $MRVL's RSI recovered to 41.6 (from 34.3), 7D improved to -3.43% (was -16.1% inside that week), but the 30-day print stays deep at -31.04% (improved from -37.17%); $ARM's RSI ticked to 37.5 (from 35.9), 7D improved to -7.82% (was -15.53%), though 30D is roughly flat at -28.97% (was -28.77%) — both names stopped bleeding for a week without confirming a floor. $NVDA's pullback eased: RSI 48.6 (up from 43.0), a +2.93% single day, though 7D stays negative at -2.94% (was -4.96%). $TSM stabilized: RSI 46.2 (up from 39.0), 7D roughly flat at 0.21% (was -7.61%), 30D -9% (improved from -13.8%) — the resumed slide from last cycle paused. $PLTR held roughly flat: RSI 44.2 (was 44.5), 7D 0.11% (was -6.88%), 30D turned negative again at -2.12% (was +6.77%) — still collapse regime and death-crossed, thesis flag still intact.

• $AMZN — PROMOTE (upgraded from WATCH): RSI 67.7 (up sharply from 36.3), +15.32% single day, -2.51% off 52wk high (was -17.12%) — an earnings-driven surge that fully reverses last cycle's "steadiest name broke" call.
• $MRVL / $ARM — WATCH (upgraded from PASS): 7D decelerated to -3.43%/-7.82% (were -16.1%/-15.53%), though 30-day drawdowns stay deep at -31.04%/-28.97% — the bleeding paused, not a confirmed floor.
• $NVDA — WATCH: RSI 48.6 (up from 43.0), 7D still negative at -2.94% (improved from -4.96%) — the pullback eased but hasn't turned.
• $TSM — WATCH (upgraded from PASS): RSI 46.2 (up from 39.0), 7D roughly flat (was -7.61%) — last cycle's resumed slide paused.
• $PLTR — PASS: RSI 44.2 (roughly flat from 44.5), 30D turned negative again at -2.12% (was +6.77%) — still collapse regime and death-crossed.

Lead pick: $AMZN is the clear standout — a +15.32% earnings-driven single day that closes the distance to a fresh 52-week high to just -2.51%, reversing last cycle's "steadiest name broke" read entirely. $MRVL and $ARM are the ones to watch next: both stopped their fresh-low bleeding this cycle, but neither has recovered enough of the drawdown to call it a floor.
