| 2026-07-17T21:19:06 | Thanks, love reading the comments! Goldman Sachs raised Innolight PT to 2581 RMB. Roughly 163.6% upside from current valuations. But the largest thing is its 2026–2028 earnings est revision raised by a whopping 65%/108%/119%, based on: - Much higher silicon photonics module volumes - scale out, … → · 1108 likes · 768,418 views |

Kospi is down -8.18% (Sk hynix/Samsung) Nikkei is down -4.8% TWSE Index is down -3.82% As you've seen with $SOI or $RKLB dropping 30-40%.

| 2026-06-26 | FYI, I posted ideas about $AXTI at $15, $AAOI at $30, $TSEM at $115, $LITE $300, $MU $300, $SNDK $400, $EWY $110, $SIVE $4. $IQE $13, $SOI $44 and so on. So when they finally have a massive correction due to macro drop the ideas are wrong? And most are still up a few hundred percent. TW CPO names… → · 205 likes · 28,846 views |

| 2026-06-23T03:16:44 | IMO photonics theme + CW laser chokepoint is goated. It's legit like markets have short term memory loss and forgot how $LITE went from $3B -> $65B+ from 2024 to now. Because $NVDA caused EML bottlenecks, and forced architectural changes. We're literally seeing the same thing today with CW lase… → · 1616 likes · 984,535 views |
| 2026-06-20T11:52:49 | I think u must be new here.

| 2026-05-25 | $RPI, close to ~3x returns. Off the media branded "Meme Stock". I think after retail saw institutions bear post my thesis posts.

| 2026-05-24 | Photonics is nuanced and using ChatGPT/Gemini makes you miss all of it: 1. $SIVE is actually a chokepoint and partially a bottleneck.

| 2026-05-23 | @ncs1912 Because I care more about novel ideas and if they get validated in markets. If someone with $4000 had a great idea about $SOI before anyone else found it.
