Personal TLDR research. Western supply chain bottlenecks like $LPTH and $AXTI: $MTRN - Beryllium (Spor Mountain) $HALEU - Uranium | SMRs $ESE - Space fuel tanks (through Vacco) $GHM - Vacuum Ejectors & Surface Condensers | U.S. Navy $FEIM - Atomic Clocks $OPXS - Light Laser Periscopes $TAYD - Vibration $PKE - Heat $VNP.TO - Western gallium $TDY - Rad-Hard Image Sensors $RDW - Roll-Out Solar Arrays $PDFS - Exensio Yield for Intel 18A $WOLF - Silicon Carbide $RELL - Ultracapacitors & Magnetrons $CPSH - Thermal / Aluminum Silicon Carbide $VREX - X-Ray Tubes $GSM - Western Silicon Metal $INTT - Extreme Thermal Cycling $CODA - Turbidity (Murkiness) $NTI - Corrosion $PLAB - Photomask $MKSI - Plasma Control $KULR - Explosive Heat $PESI - Radioactive mixed waste. $CVV - Gas-to-Solid Deposition. $LPKFF - Laser Induced Deep Etching/ Glass Substrates These are just more of the "under the radar" small caps I was researching -> ended up choosing $AXTI and $LPTH if people were interested. Lot of them have terrible fundamentals despite being vital eg: $IQE (already pretty known), so it's not a good idea to just blindly buy a bottleneck. There were a lot more out there I haven't finished researching (so didn't include), and it's a lot harder to pinpoint ones that haven't been priced in. But wouldn't be surprised if a lot of these went up 5x over the next year.

$AAOI is another photonics name that has just doubled in the last two months! Feels like every photonics company from $AXTI and $AAOI has been doubling or tripling recently? I’ve dubbed this the “Elite Four” for photonics exposure: 1. $LITE (High BOM of the TPU) 2. $AXTI (Materials for Eveything) 3. $COHR (huge part of supply chain) 4. $AAOI (made in America) Others like $IQE I’ve personally added recently slightly more for risk-on portfolios (epiwafer foundry for $LITE and others), but don’t have a great financial profile. That being said glad 2 months later, a lot of these names are taking off

Feels bad, -49.4% drawdown this month after the recent crash. My portfolio is mainly AI chokepoints and bottlenecks. In the memory, photonics, robotics, and upstream semis, (on margin) which all tend to be higher beta than others. But reduced leverage recently from the crash. t.co/fVpe36QHJC t.co/S8sCF8BrpF
