Long
Score8/10RSI(14) 54.7Off 52w high -15.8%P/E (TTM) 383Position P/L Long since 7/4, back to green

Technicals — Up 6.7% to $419.77, reclaiming all three moving averages ($399/$407/$419) in one move — retaking the 200-day is the key trend-turn signal. RSI 54.7 just past neutral, momentum not spent; $450 is mid-June trapped supply, daily ATR $20 (~5%).

Fundamentals — Q2 deliveries of 480K (+25% YoY) are in the books, ending the two-year slide; Miami becomes the third robotaxi city, reviving the autonomy story. But 383x earnings fully prepay robotaxi and Optimus success — Morgan Stanley models a 30,000-vehicle fleet by 2030, so you're buying a decade-out option today.

News — The 7/6 Miami robotaxi launch is the direct catalyst — covering select central/western zones, excluding downtown and the beach, an early milestone rather than commercialization proof. The market frames it as a relief rally. The real verdict is 7/22 earnings: margins and ASPs.

Short-term · 1–3 weeks
Long Bullish

Reclaimed the 200-day with a moving-average alignment forming plus momentum — turning bullish short-term. A held retest of $405–415 confirms; target the $450 supply. A break of $390 (below the 200-day) fails the reclaim — exit. Don't be full-size into the 7/22 print.

Neutral

Deliveries back in growth, energy storage scaling, and the robotaxi/Optimus options are a real growth story — but 383x prepays most of it. Keep a core for the optionality; save the heavy add for a valuation air pocket.

Long
Score8/10RSI(14) 42.0Off 52w high -17.3%P/E (TTM) 29.9Position P/L Long since 7/4, +0.4%

Technicals — Up just 0.4% to $195.55 on a broad chip-up day, repeatedly confirming the 200-day ($191) as support. RSI 42 is soft but not oversold; the 20/50-day ($202/$210) cap upside. Its lag vs. AMD is short-term flow rotation, not a fundamental slip.

Fundamentals — Revenue +70.7%, EPS +110%, and 29.9x is still the cheapest percentile in a year. As BofA notes memory is now 35-40% of cloud AI capex, compute's core remains NVIDIA. SK Hynix's 7/10 listing may pull short-term flow from compute to memory, but order visibility into 2027 is intact.

News — No fresh stock catalyst — riding the chip rebound but clearly lagging AMD. Focus is on SK Hynix's 7/10 listing and memory-chain upgrades, leaving the compute leader on the weaker side of the narrative rotation. The $191 200-day is the line everyone watches.

Short-term · 1–3 weeks
Long Lean bullish

Repeated 200-day confirmation, cheapest multiple in a year, and a chip-rebound tailwind — keep the long. A break of the 50-day ($210) opens upside; a break of $178 (one ATR below the 200-day) signals reversal — take the loss.

Pricing power in AI compute plus the CUDA moat are intact; 29.9x for 70% growth is a rare 'growth stock at a value multiple' window, with sovereign-AI and government orders opening a second curve.

Score7/10RSI(14) 57.4Off 52w high -5.6%P/E (TTM) 1813-month gain +153%

Technicals — Up 6.6% to $552.05, closing on the $584.7 52-week high, above every moving average ($518/$465/$280) — a fully intact but very steep uptrend. RSI 57.4 has room; ATR $37 (~7%) means any pullback is violent.

Fundamentals — The MI400 series (432GB HBM4, +50% over MI350) mass-produces in H2, with analysts estimating $7.2B of 2026 revenue, ~25% of datacenter sales. Revenue +35%, EPS +123%, but 181x trailing already prices 2027 delivery — any MI400 timeline slip hits the multiple directly.

News — The July Advancing AI 2026 event nears and the market front-runs MI400 details. AI chips added a combined $2T in July, with AMD — NVIDIA's top challenger — a prime beneficiary. A potential China catalyst is also brewing.

Short-term · 1–3 weeks
Long Lean bullish

The Advancing AI catalyst plus an impending breakout favor a momentum long. But a slope this steep isn't for fresh heavy size; stop below the $500 round number. A 7% ATR on 181x amplifies any sector panic.

Inference is bigger and longer-lasting than training, and AMD's price-performance play is structurally favored. With datacenter and client both firing, 2027 earnings can grow into the multiple; pullbacks toward the 50-day are long-term adds.

Score8/10RSI(14) 49.0Off 52w high -21.5%P/E (TTM) 22.3Revenue YoY +167%

Technicals — Up 0.9% to $984.75, stabilizing this week after last week's flush; the 50-day ($862) is firm support with the 20-day ($1043) to reclaim. RSI 49 back to neutral, daily ATR $93 (~9%) still extreme. The $1,000 round number is the next battleground.

Fundamentals — Fundamentals re-embraced: UBS lifts Q3 DDR contract pricing to +32% QoQ (from +17%), calling DRAM undersupplied 'until at least 2Q28.' Revenue +167% at 22x, and BofA notes memory is 35-40% of cloud AI capex yet trades at 10x forward — a clear mispricing.

News — Jul 6 memory rebound: UBS, Citi and BofA all turned bullish the same day, the DRAM ETF +7%, Micron +2%. Citi added Micron to its 90-day upside catalyst watch. The risk: SK Hynix's 7/10 Nasdaq listing could rotate money from Micron into the lower-priced HBM leader.

Short-term · 1–3 weeks
Long Lean bullish

Bank upgrades plus a repaired supply-demand story shift this from sidelines to lean bullish. Reclaiming $1,000 opens the bounce toward the $1,150 gap above the 20-day. A break of the 50-day ($862) falsifies it — exit. SK Hynix's listing may add near-term chop.

The AI memory supercycle gap hasn't closed: HBM capacity is locked under long-term deals and UBS guides tightness to 2028. 22x against triple-digit growth is cheap; pullbacks are a gift for the long book — scale in, keep dry powder.
