List of 30 US stocks with brief bullish theses covering semis, AI, space, rare earths, etc.

Evidence & details
Evidence
  • +Photonics stocks (LITE, AAOI) are dropping 10%+
  • +Sandisk dropped 10%+ signaling sector weakness
  • +Japanese export controls on InP will limit supply for western optical buildout
  • +COHR is already capacity strained and will worsen with Sumitomo, JX affected
  • +AXTI becomes a monopolistic bottleneck for InP substrates
Catalysts
  • ⚑If Japan removes export control ban on InP (unlikely)
  • ⚑If AXTI delivers substrates at scale after $100m funding to double capacity
  • ⚑If pricing premium downstream like HBM offsets product supply shortage
Risks
  • βˆ’Supply chain vulnerability due to Japanese export controls
  • βˆ’Monopolistic bottleneck by AXTI
  • βˆ’Continued sell-off in photonics sector

@RonDeSantis Hi Ron, so there's two different parts to it: 1. Hyperscalers ( $ORCL, $META, $AMZN): They're spending more than they have with profit ( $GOOGL is the rare exception, and $AAPL isn't really spending much relatively). So markets are worried less worried it's transl…

Thesis: General discussion of hyperscaler AI spending, supply chain vulnerabilities, rare earth dependency, and geopolitical risks without specific actionable thesis on any ticker.

@Bonek2801 Risk management purposes. I’d rather hold 50% in Bitcoin around $70K than sit on cash to lower volatility. Also the downside risk of $VPG is $TSLA creating their own sensors and vertically integrating it away. Similar bear case with $GOOGL and OCS with $LITE though.

Thesis: Downside risk for VPG from TSLA vertical integration; similar bear case for LITE with GOOGL.

We’re seeing third order effects in markets with $LITE, $AAOI, and photonics having a bloodbath, dropping 10%+. It’s multifaceted, with sector drop from Sandisk -10%+ and others selling off as well. But my nuance take is that the entire Japanese supply chain will likely run out…

Thesis: Japanese export controls on InP will cause supply chain constraints for western photonics players, affecting LITE, AAOI, COHR, and potentially exacerbated by AXTI's monopoly, leading to continued sell…

@RyanMDorsey23 This is a research note on point failure of the entire AI buildout in $AXTI/China from both substrate production and laser-grade Indium Phosphide. I’m not doing valuation analysis on individual companies But if this flow stops, $LITE, $COHR, $AVGO to $GOOGL, $MSF…

@LoganMacGregor9 Good question about risk, I enjoy talking about the downsides too. 1. Hyperscalers completely their own datacenter buildout with GPUs (TPUs with $GOOGL, Tranium with $AWS), energy, locations in 5+ years. This is the analogy of Qualcomm with Apple. Apple just u…

Waymo (GOOGL) dominates robotaxi with Level 4, while Tesla's FSD is Level 2 and requires human monitoring, making it snake oil; competition with Avride+Uber is key.

Nvidia is a strong buy on the dip despite competitive threats from hyperscaler custom chips like Google TPU, due to blowout earnings and $500B backlog ensuring dominance for at least two years.

Own both GOOGL and NVDA for AI exposure; GOOGL is less risky due to diversified catalysts, while NVDA offers higher upside if AI accelerates with robotics/agents.

The post compares Level 4 readiness of NBIS (Avride) and GOOGL (Waymo) vs TSLA's Level 2 FSD, highlighting that TSLA's claims are marketing while competitors already have working systems. It acknowledges TSLA's scalability advantages but notes current operational shortcomings.

InP substrate supply is a critical bottleneck for AI photonics, with a duopoly of $AXTI and $SMTOY controlling majority supply. Hyperscalers' AI programs (TPU v7, Maia, MTIA) are tethered to these companies, leading to price spikes and potential delays.

Personal stock ratings with detailed commentary: Strong Buy on 14 stocks (SNAP, META, MU, TSM, etc.) citing catalysts like memory supercycle, bottlenecks, and AI tailwinds. Buy on 32 stocks including COIN, SMCI, GOOGL, and several crypto and drone plays. Questionable on VELO and SKYT due to weak fundamentals. Avoid on 11 stocks (UAVS, BKKT, PLTR, etc.) due to dilution, high debt, or overvaluation. Overall bullish on AI, memory, bottlenecks, made-in-America supply chains, and defense, with a long-term view until after midterms.
