Quick verdict
VSH is net bullish (1 bull · 0 bear)
US-listed companies like VSH are worth considering due to their domestic listing, despite having less market share than Asian counterparts.

- @wannabepanacea Yeah as the other comment said $VSH and $KN are the two to look at. They have a lot less market share than their Asian counterparts, but... they're listed in the US
- Some updates on bottleneck timelines: - ABF substrates: 1 year / eg. Ajinomoto (2802) for ABF film, Ibiden, Unimicron, Nan Ya PCB, etc make the substrates - HDI Boards: Over 6 months / Victory Giant (300476), Zhen Ding (4958), Unimicron, Compeq (2313), Meiko (6787) - Multilayer boards: ~6 months / Victory Giant, WUS (002463), $TTMI, Gold Circuit Electronics (2368), - CCL: Over 6 months (severe shortages of materials) / Elite Material (2383), Shengyi (600183), TUC (6274), ITEQ (6213), Nan Ya Plastics (1303), Resonac (4004) Mitsui Kinzoku (5706) / HVLP copper foil. Nittobo / glass fiber/cloth - MLCCs, chip resistors, tantalum capacitors, aluminum electrolytic capacitors: 15-20 weeks to 1 year+ MLCC: Murata (6981), Samsung Electro-Mechanics, TDK (6762), Taiyo Yuden (6976), Yageo (2327), Walsin (2492) Chip Resistors: Yageo, Walsin, KOA (6999), Rohm (6963) and $VSH Tantalum capacitors: Kyocera/AVX, Yageo/KEMET, $VSH again Aluminum electrolytic capacitors: Nippon Chemi-Con (6997) Nichicon (6996) | Timelines sourced from Digitimes, did the honors of adding in related companies. But it's slightly more nuanced since MLCCs and others mix. in commodity types vs. AI DCs. Regardless, just some helpful mapping.
- Okay chat, here's your compiled list chat of your favorite 800V DC related ideas. 1. $IFNNY - $115.8B 2. $ON - $46.2B 3. Lite-On (2301) - $16.03B 4. 6504.T - $14.1B 5. $VICR - $12.8B 6. $LFUS - $11.57B 7. https://t.co/1unM4FPf65 - $8.34B 8. $VSH - $7.86B 9. $ENPH - $7.36B 10. $NVTS - $5.77B 11. $POWI - $4.30B 12. $BDC - $4.18B 13. $EOSE - $3.86B 14. $SEDG - $3.82B 15. $AEHR - $3.1B 16. 6890.T - $2.66B 17. $WOLF - $2.16B 18. $CWR.L - $1.75B 19. $AMSC - $1.68B 20. https://t.co/43OXU9tx65 - $1.68B 21. $XFAB - $1.54B 22. $AOSL - $1.25B 23. $HYLN - $1.23B 24. $FCEL - $835M 25. $IQE.L - $780M 26. $ASYS - $276M 27. $RELL - $239M 28. 6844.T - $222M 29. 4973.T - $207M 30. $PAY.BR - $189M 31. 6616.T - $186M 32. 6882.T - $124M 33. $IPWR - $96m Also included some adjacent ones you all mentioned like $FCEL or $EOSE anyway, tho idk it's great exposure. Ignored the clearer irrelevant stuff like $POET that people mentioned tho. There's like 500 comments, but I guess X limits everything I can see. We'll see how your highest conviction ideas do.
