Anonymous deep-dive analyst mapping the AI photonics small-cap supply chain layer by layer
Builds bottom-up, primary-sourced theses on the AI optical/p
Grade = how their written analysis reads (A best). Trader score = how their last-20 timestamped calls performed vs SPY. · Analyst brief as of 2026-06-22.
Across their last 20 scored bets: 35% hit rate, -0.12% mean alpha, trader score -0.12. Their last-14d mentions, direction-adjusted, have moved -14.2% since posting (mean over 48 mentions with price data).
PhotonCap is centered on AI data-center optical infrastructure, especially coherent PICs, optical memory fabric, light-source suppliers, and test bottlenecks. The distinctive read is that Rubin SOCAMM cuts reflect supply, power, and heat limits rather than demand weakness, pushing the stack toward optical fabric. Position-level activity is sparse: he disclosed SPCX allocation and watched LPTH for add timing, while explicitly saying he does not hold CRDO.
The week is concentrated in AI data-center optical infrastructure, with repeated bullish framing around optical memory fabric, coherent PIC production, and light-source suppliers. Concrete trading disclosure is limited to SPCX allocation and LPTH add timing, while CRDO is explicitly not held. SPCX is the main concentration and pump-risk area, with allocation disclosures alongside valuation and bubble questions after the move above $200.

Grade is our human read-worthiness rating; trader score is a rolling 20-bet hit-rate/alpha composite — different things, often disagreeing. “Since then” is direction-unaware in the table; the summary line above adjusts for which way they leaned.
