One concentrated frontier-tech portfolio, documented in public. Rocket Lab stopped being a launch proxy and started becoming a space platform — while the chip trade cracked and the grid quietly revealed the next bottleneck.
For three months my space thesis was a halo trade: own the public names, ride the SpaceX wave, collect the spillover. This week it became something bigger. Rocket Lab — the little launch company I bought at $57 — announced it's acquiring Iridium, a profitable satellite-communications business, for eight billion dollars. The stock jumped 16%. It's no longer just a rocket. It's a consolidator, using its own elevated stock to roll up the space economy while the sector is full of small, cash-strapped public companies ripe for the taking.
The deal lit the whole complex — Planet Labs, which I also own, jumped in sympathy. Alphabet debuted in the Dow, SpaceX picked up a fresh index catalyst, and the market closed a powerful quarter with frontier assets no longer moving as one crowded trade. My self-reported book crossed a new high during the week.
At the same time, the largest U.S. power grid prepared for record demand as heat and data centers hit together. That matters because the frontier story is widening: launch companies are becoming communications platforms, and AI is becoming an electricity, cooling, transmission, storage, and materials problem. The next winners may not look like the last ones.
And then the back half of the week reminded me the run isn't a straight line. A second straight semiconductor rout knocked Micron down 5.5% Thursday, and because I still haven't trimmed it, my biggest position dragged the whole book off its high. The thesis grew up this quarter. My discipline about position size did not. That's the story.
The map before the positions. ● firing ● mixed/watching ● next-wave seed ● headwind.
The split couldn't be cleaner: the Dow set a record while the Nasdaq fell, as money rotated out of the semiconductors that carried the best quarter since 2020 and into everything else. The soft jobs report is dovish — good for rates — but it landed the same day chips had their second ugly session. My book is caught in the middle: space and Dow-style names up, my oversized memory position down.
Rode: RKLB's 16% Iridium pop and PL's 16% sympathy move. Got bit: MU −5.5% in the chip rout, dragging the book off its high — the un-trimmed concentration, live. Standing order, now overdue: right-size MU first, then reassess RKLB after the Iridium deal’s financing and dilution are fully understood. Rebuild cash deliberately instead of trimming two different theses by reflex. The dovish jobs tape is a calm backdrop to finally do it.
"When a company you bought as a launch proxy starts making eight-billion-dollar acquisitions, the thesis didn't just work — it changed shape. Value the company in front of you, not the one you bought in April."
I bought Rocket Lab as a SpaceX proxy — a way to own the space catalyst without the IPO. It doubled. But Monday it stopped being a proxy. Acquiring Iridium for $8 billion turns RKLB into a vertically integrated space company: launch, manufacturing, and a profitable satellite-services business throwing off recurring revenue. That's a consolidation play in an industry about to have a lot of small, cash-strapped public companies for a well-capitalized acquirer to absorb.
The mistake would be anchoring to my old reason for owning it. The new question isn't "is RKLB a good SpaceX proxy" — it's "is RKLB the company that rolls up the public space economy." If yes, it's still cheap after doubling. If it overpays and integration drags, the thesis breaks. Either way I have to value the company in front of me. The same logic cuts the other way on Micron: I own it for a memory-scarcity thesis that's fully intact — but "the thesis is right" was never the same as "the position is the right size." This week proved it.
For four issues I've flagged that Micron is too big and promised to trim it. For four issues I haven't. And this week the market finally collected on that procrastination: a two-day chip rout knocked MU down 5.5% on Thursday alone, and because it's still ~21% of my book, that one name pulled my whole account off its all-time high. The risk I kept describing in the abstract showed up as an actual dollar amount. That's what unmanaged concentration does — it's invisible right up until the day it isn't.
Here's the honest read: I got lucky that it bit on a −5.5% day and not a −25% one. The thesis is intact — Micron guided to $50 billion a quarter, the memory scarcity is real, and I'm not selling the position. But "don't sell it" and "don't let it be a fifth of the account" are two completely different statements, and I've been hiding behind the first to avoid doing the second. A soft jobs report just handed me a calm, dovish tape to trim into. No more "next issue." The first move is still MU, because that is the single-name concentration I already identified. RKLB deserves a fresh valuation after the Iridium deal before I treat a strong move as an automatic sell signal.
Four issues of narrating discipline. Time to be able to say I did it.
Ninety-three days. $5,270 deployed, ~$8,672 on the board, +65% through the best market quarter since 2020 — and a week that delivered both the highlight (Rocket Lab's $8B space consolidation) and the warning (my oversized Micron dragging the book off its high in a chip rout).
Both halves of that sentence matter. The thesis is doing everything I hoped: space is maturing from halo to roll-up, memory is scarce and profitable, the frontier is real. But an extraordinary quarter is precisely when concentration is most dangerous, because a hot hand feels like a reason to stay lopsided. It isn't. The chip rotation this week was a small, cheap lesson — a −5.5% MU day, not a −25% one — and the smart response to a cheap lesson is to act on it before the expensive version arrives.
So quarter two starts with one job, and it isn't a new pick: right-size the known single-name risk, reassess the newly transformed Rocket Lab thesis, rebuild the powder, respect the rotation and the Iran headline risk, and stop confusing a great run with permission to skip the discipline. The frontier delivered. Now I protect it.
See you next Sunday, buddy. — Alex
