Reason: MRVL and ARM both reversed last read's "drawdown easing" into fresh new lows - each posting a single-day drop over -7.7% and a 30-day print worse than -37%/-28%; NVDA's reversal-higher gave itself back (RSI 51.0 to 43.0); AMZN and TSM resumed their declines too; PLTR's collapse regime holds even as its 30-day print flipped positive.

Tape Read

$MRVL is the flag this cycle: last read's "improving pace" call — a 30-day drawdown that had eased to -29.79% — reversed hard into a fresh -37.17% 30D print, with a -7.77% single day sitting inside a -16.1% weekly decline, RSI down to 34.3. $ARM moved the same way: RSI 35.9, a -15.53% week, an -8.11% single-day drop, and a 30-day print that widened to -28.77% (was -27.59%) — last cycle's "not a floor, a slower bleed" read just confirmed itself with a sharper leg down. $NVDA's stabilization reversed too: RSI 43.0 (down from 51.0), 7D back to -4.96% (was +1.99%) — the first genuinely positive week in this file's recent run gave itself right back within a cycle. $AMZN's RSI held roughly flat at 36.3 (was 37.2) but the 7D print worsened to -6.74% (was -6.12%) and it's now -17.12% off its 52-week high (was -16.12%) — the "steadiest name broke" call from last read hasn't recovered. $TSM resumed its slide as well: RSI 39.0 (down from 42.3), 7D -7.61% (was +1.27%) — last read's pause reversed back into decline, 30D now -13.8% (was -8.49%). $PLTR is the outlier: RSI 44.5 (up from 41.9), still collapse regime and death-crossed, but its 30-day print flipped positive to +6.77% even as the 7-day stays negative at -6.88% — the thesis flag stays intact despite the regime read.

• $MRVL / $ARM — PASS (further downgraded): 30-day drawdowns worsened to -37.17%/-28.77% (were -29.79%/-27.59%), each posting a single-day drop over -7.7% — last read's "improving pace" fully reversed into a fresh new low.
• $NVDA — WATCH (downgraded from upgrade): RSI 43.0 (down from 51.0), 7D back to -4.96% (was +1.99%) — the reversal-higher that had just turned positive last cycle gave itself back.
• $AMZN — WATCH: RSI 36.3 (roughly flat from 37.2), -17.12% off 52wk high (was -16.12%) — no recovery from last read's break, the decline just continues at a similar pace.
• $TSM — PASS (downgraded from WATCH): RSI 39.0 (down from 42.3), 7D -7.61% (was +1.27%) — last read's pause reversed back into decline.
• $PLTR — PASS: RSI 44.5 (up from 41.9), still collapse regime and death-crossed, though 30D turned positive at +6.77% — the metric wiggle doesn't change the pass call.

Lead pick: No clean promote in this basket this cycle — every name that had shown a stabilizing sign last read (NVDA's reversal, MRVL/ARM's easing drawdowns, TSM's pause) gave it back. $MRVL is the clearest flag: a -7.77% single day inside a -16.1% week just turned an "improving pace" call into a fresh 30-day low.
