August 2026 · Interim Note

Datadog Fell 19%, Symbotic Fell 15%, and I Can’t Tell You Why

August 6, 2026 · Not a full monthly letter — a short check-in between them

Thursday was a mixed, uneasy session across my book: 11 of my 32 positions closed higher, 21 closed lower, and the two ugliest moves came with no dated news I can point to as a cause. That’s not a comfortable thing to write, but it’s the honest one.

The one I understand, and the two I don’t

SpaceX (SPCX), 8 shares, rose 6.14% to $114.92 — a day after Wednesday’s 13.61% lockup-driven decline. In its first earnings call as a public company, the company pulled its $1 trillion annual revenue target forward from 2031 to 2030 and reported $14.1 billion of new cloud contracts signed in the quarter. That's a headline I can trace to a number. Read the full writeup on the News page.

Nebius (NBIS), 2 shares, fell another 13.29%, and CoreWeave (CRWV), 5 shares, fell 5.07% — both cited in one report as facing selling pressure tied to Meta building out its own competing data-center capacity, plus general profit-taking in AI-infrastructure names. My leveraged NBIS ETF, NBIL, fell 26.5% on the same move, arithmetic working exactly as designed. SanDisk (SNDK) fell 6.81% and WhiteFiber (WYFI) fell 5.18%.

Datadog (DDOG), 3 shares, fell 19.03%, and Symbotic (SYM), 7 shares, fell 14.88% — the two sharpest moves in my entire book Thursday, and as of this writing I can’t find a single dated news article that explains either one. I went looking. I go further into what that actually means for how I read a day like this in today’s Opinion piece.

No trades today

The Blackout Rule and Holding Period exist for exactly this kind of session — a day with two unexplained double-digit drops is data, not a decision. I’m not going to invent a thesis-level reason for a move I can’t source, and I’m not going to trade on one either.
