Before we get into my new picks a quick position update.

I am quite chuffed with JCU Corporation, up 47% since my post in December. It hasn’t blasted off like other bottleneck plays- but it was always the most compelling Risk to Reward play for me, and I had this sitting at a 40% position initially.

I have reduced exposure because my portfolio suddenly became a one-trick pony, and I’d rather not have all my eggs in one basket.

I found the Chosen (one) Stock.

JCU Corporation (4975.T) Update

  • Increased operating profit by +16.4% YoY with the chemicals segment up +9.5% YoY.

  • One question I have been trying to answer relentlessy is the bottleneck potential for names like JCU Corporation and C. Uyemura.

  • JCU Corporation has more optionality towards hybrid bonding in HBM with its TIPHARES brands - so it might see more upside late 2027, 2028.

  • C. Uyemura has more direct exposure to the current AI buildout in its chemicals segment “Wafers & PKG”.

But could the chemicals used hit a bottleneck?

The graph below is for C. Uyemura specifically, BUT, and huge BUT, this information relies heavily on my understanding of their processes.

A bottleneck would occur for chemicals because qualification takes long, there could be a point at which engineers are waiting for new capacity to be qualified but chemicals production capacity hit a bottleneck. But- huge disclaimer- I need to confirm this. If I can, JCU and C. Uyemura could be an early bottleneck play.

I am looking for any expert in this field to please reach out to me regarding the bottleneck potential here.

The other AI adjacent plays I profiled: Wasion Holdings and ChongQing Machinery & Electric Co LTD have both done even better. - Sometimes just recognizing the value others are putting out on Substack and X is all you need to beat the benchmark twice over.

Ever grateful to Maius Partners for ChongQing Unpacking Uncertainty for Wasion Holdings. If you want some alpha- follow these guys. Unpacking Uncertainty with only 456 subs on Substack? Undervalued.

Wasion Holdings (3393.HK) Update

Wasion Holdings doubling in share price since the mention. And I took some profits yesterday. But I am also still holding a position as Wayon Energy gets spun-off.

Wayon Energy has three business segments:

1- Smart Distribution Network: Smart Switchgear, high-efficiency transformers, and “Smart Distribution” solutions.

2- Data Center: Power infrastructure projects for power distribution modules, IT containers, HVDC power supply systems. There will be massive growth for this many years out.

3- Energy storage. Energy storage systems and PV + storage microgrids.

  • The big story is value-unlocking. Wasion is proposing to spin-off Wayon Energy.

  • I believe the share price has increased in part due to the value-unlock and most-part due to the fact that the market realizes its an AI buildout beneficiary.

ChongQing Machinery & Electric Co LTD (2722.HK)

2722.HK doing a solid 40% but still looking fairly priced and still largerly exposed to the AI buildout in China, which seems to lag behind the U.S.

So what’s next? What do I do with my big bag of profits?

Well I have two new picks. One is quite under-followed, the other has very recently started making the rounds on X.com

I believe both are worthy investments.
