I'm long $TSEM, the $TSM of photonics. My top two picks for CPO are $SOI and Tower Semi. Given the $NVDA GTC catalyst on new photonic related architecture next week: I expect Tower Semi to get a huge catalyst. Nvidia laready directly collaborated with Tower to scale 1.6T silicon photonics last month (hint hint for GTC), likely pushing the downstream players to use it. And now, Tower is the leading supplier of 1.6T SiPh PICs and the primary foundry for scale-up CPO architectures. (the other being global foundries) From my forward est: 2028 Forward P/E: ~16.8x to ~18.1x (Tower set a target $2.84B revenue by 2028, with ~31.7% operating margin, ~$750M in net profit) The thing to note is over 70% of their planned SiPh capacity is already reserved through 2028. And photonics haven't even ramped up yet. So, I expect them to strongly beat earning projections due to extreme photonics scaling + allocations price hikes that's not modeled into projections. Also, $TSEM is heavily de-risked by 70% of capacity already being reserved. MC is likely due to $TSEM being a very obscure upstream player in the photonics supply chain. But I expect the $NVDA GTC conference to be that catalyst that brings it to premium valuations. I'm long $TSEM as an asymmetrical upside for upstream photonics foundry layer.

Trade idea that I published to my shower thoughts channel: Korean Index volatility arbitrage and taking advantage of Black-Scholes models. $EWY long options seem mispriced. This is Blackrock's Korea Index, which is majority memory (Samsung Electronics, Sk Hynix). The stock swings 2-5+% a day, and is up 136.25% 1Y, despite priced like a normal index IV. Samsung is volatile. SK Hynix is volatile (eg. 65% - 80% est). But the combination of the two through the index is priced way less than both low beta $GOOGL (37.33%) and $AMZN (39.12%) at ~32% IV. I've been watching $EWY for a bit and it does look volatile. As for pricing my guess is MMs priced in IV based on historical averages (5-10 years), where the Korean index was completely flat. And were expecting calls 2 years out to revert to the mean. But this volatility should be the new norm as markets price in the new memory supercycle (eg. $TSM went from 30% IV to 46.2% IV). Long calls should benefit from both Samsung + Sk Hynix carrying the index. And the main benefit is vega expansion that you won't get from $KORU. You also can't get this option MM pinning like individual US stocks since this is Korea's national index and long term. TLDR: Individual components SK Hynix + Samsung are highly volatile. They're basically half of the index, but options in index are priced with low volatility, perhaps due to historical 5-10 year data. Long calls benefit from vega expansion that weren't priced in correctly as MM forward vol estimates are anchored too heavily on historical realized vol, which was low for $EWY over the past 5-10 years
