Who benefits from a Chinese optical transceiver ban?

In this post we discuss an emerging Malaysian photonics manufacturing partner that stands to benefit from the need to diversify away from optical transceiver manufacturing in China.

As we’ve pointed out a few times before, Malaysian semiconductor stocks have been remarkably resilient, and many did not pull back in July at all. It appears that capital is longer duration and semis / DCs/ manufacturing probably has little competition with other sectors as a destination for investment.

ViTrox is a notable example:

Earlier this year, we also flagged a small cleanroom contractor that has doubled since July, which speaks to the amount of investment happening in Malaysia.

By popular request, we’re presenting a bull/bear case for a company that is working with US photonics players like Lumentum and Coherent. If you’ve been following photonics, you’ll understand that demand is not in question - this company will get as many orders as it can reliably deliver, and so its ability to multibag arguably turns only on execution.

I think I should also caveat this by saying that I have not personally met the company or checked the numbers shared with me below, but I did think it was worth publishing because of the identity of the people who shared the idea - there is pretty serious attention on this stock.
