Long
Score7/10RSI(14) 49.6Off 52w high -19.2%P/E (TTM) 368Position P/L Long since 7/4, +2.4%

Technicals — Down 4% to $402.9, surrendering the just-reclaimed 200-day ($418.5) and barely holding above the 20-day ($399.8). The robotaxi thrust gave back most of itself in a day, turning $399–418 back into a meat grinder. RSI 49.6 neutral; direction stays unresolved into the 7/22 print.

Fundamentals — The +25% Q2 deliveries and Miami robotaxi are priced; at 368x the market now interrogates 7/22 margins and robotaxi economics. Rivian's dilution rout soured the whole EV tape, and richly valued growth had nowhere to hide on a chip-selloff day.

News — No fresh stock-specific negative — the pullback is the EV sentiment hit from Rivian's raise compounding the broader tech selloff. Robotaxi remains 'an early milestone' in the market's framing; the 7/22 print is the valuation courtroom.

Short-term · 1–3 weeks
Long Lean bullish

Keep the long but downgrade to lean bullish: the failed 200-day reclaim weakens the trend signal, with the 20-day ($399.8) and the $390 stop as twin defenses. Hold them and there's room to repair into earnings; below $390, exit unconditionally — don't gamble the print.

Neutral

Deliveries back in growth plus storage plus the robotaxi/Optimus options are a real story; 368x is a real price. Keep a core for the optionality, save size for valuation craters — the market reteaches this lesson quarterly.

  • A margin miss on 7/22 puts the multiple on trial
  • Robotaxi expansion lags the narrative
  • EV sentiment whiplash (the Rivian-raise hangover)

Long
Score8/10RSI(14) 43.5Off 52w high -16.7%P/E (TTM) 30.2Position P/L Long since 7/4, +1.1%

Technicals — Up 0.7% to $196.93 on a chip-bloodbath day, holding the 200-day ($191.3) a fourth straight session — the rumor targeted its share and it was the most resilient name anyway. That relative strength is the chip tape's most important signal this week. The 20/50-day ($202/$210) still cap.

Fundamentals — The DeepSeek own-chip report was the selloff's bullseye, but this script ran in early 2025: cheaper inference ultimately expands total compute demand. 30x against +70% revenue growth is still the cheapest percentile in a year, with order visibility into 2027.

News — Reuters reported DeepSeek is building its own AI chip to compete with NVIDIA — another entry in the China-inference-localization story. Yet the day's selling hit AMD, Broadcom and Marvell while NVIDIA ticked up: the market voted with its feet on whose moat is deeper. WSB mentions doubled to 219.

Short-term · 1–3 weeks
Long Lean bullish

Keep the long: the bullseye name was the most resilient, with a four-day 200-day hold, bottom-percentile valuation, and doubled mention flow. Clearing the 20-day ($202) opens the repair; below $182, take the loss.

Pricing power plus the CUDA ecosystem remain unshaken, and the cheaper-inference script has historically expanded total demand. 30x for 70% growth, with sovereign-AI and government orders as the second curve.

Long
Score7/10RSI(14) 51.2Off 52w high -11.7%P/E (TTM) 169Position P/L Long since 7/4, -0.3%

Technicals — Down 6.5% to $516.11, giving back yesterday's gain almost exactly and slipping just under the 20-day ($520.8). The uptrend structure holds (the 50-day at $469.6 is far below), but a slope this steep costs you 7%-ATR elevator rides. The $500 round number is the bulls' floor.

Fundamentals — Samsung's print and the DeepSeek chip report double-teamed richly valued AI silicon, and AMD's sector-high beta took the first hit. The MI400 H2 ramp and the 7/23 Advancing AI narrative are unchanged — 169x prices flawless execution, and volatility is simply a property of that multiple.

News — Briefly -7% to $508 on sector profit-taking and 'sky-high expectations vs. straining fundamentals' angst — no stock-specific negative. Into the event, any noise on Helios rack systems or customer commitments gets amplified; the event-driven sword cuts both ways.

Short-term · 1–3 weeks
Long Lean bullish

Keep the long: structure intact, the 7/23 event is a clear catalyst. But tighten the stop to $495 (one buffer below the round number), and don't add — volatility only grows into the event.

Inference is bigger and longer than training, and the MI400 (432GB HBM4) is the next card in the price-performance play. 2027 earnings can grow into the multiple; deep squats near the 50-day are long-term adds.

  • An underwhelming 7/23 event means a -20%-class de-rate
  • DeepSeek-style in-house chips erode China inference demand

Score8/10RSI(14) 46.3Off 52w high -25.2%P/E (TTM) 21.2Position P/L Long since 7/7, -4.7%

Technicals — Down 4.7% to $938.38 as Samsung's print interrupted yesterday's stabilization, but it still trades above the 50-day ($871). RSI 46 neutral; the $880 stop (a buffer above the 50-day) is intact. At a 9% daily ATR this drawdown is within noise — the 50-day at $871 holds the verdict.

Fundamentals — Samsung grew profit 19-fold and still missed the loftiest bar — memory expectations are stretched to the limit, and that, not demand weakness, drove the pullback. UBS's 'undersupplied to 2Q28' and BofA's $1,550 target didn't change in a day. 21x against +167% revenue — a deeper dip just improves the odds.

News — Samsung's print plus the DeepSeek report double-hit memory: Micron -4.7%, SanDisk -7.3%. SK Hynix's 7/10 Nasdaq listing countdown keeps the reallocation question alive. Still #1 on WSB at 681 mentions and warming — retail attention hasn't left.

Short-term · 1–3 weeks
Long Lean bullish

Keep the long: the dip came from stretched expectations, not weakening fundamentals, and the upgrade thesis stands. $880 (a buffer above the 50-day) is the iron stop; the Hynix-listing rotation on 7/10 is a known variable, not a new risk.

HBM locked under long-term deals in a cycle tight to 2028, at 21x against triple-digit growth. Memory is 35-40% of cloud AI capex yet trades at 10x forward — the mispricing case gets better as it falls.
