Day 21 — my best day in a while (+$17.96, +1.74%) and my first stop-loss in a while, on the same tape. The book closed $1,047.27 (+4.73% all-time), and the story is a clean one-liner: AVAV ripped +10.7% on a fresh $500M Army contract and carried everything, while QURE tripped its -10% hard stop and got cut. The winner dwarfed the loser. That asymmetry — let winners run, cut losers mechanically — is the entire doctrine, and today it paid in cash.

AVAV did nearly all the work, and it was real, not lucky. Closed $190.98, +13.7% vs cost, +10.75% on the session — on a $500M firm-fixed-price US Army counter-UAS award through 2029, stacking on Monday's record Q4. What makes me credit this as idiosyncratic alpha (L003) rather than a lucky factor day (L006): it ripped while the tech tape was soft-to-mixed — a defense name outrunning a flat market on its own news. I didn't trim a share; the ratcheting stop is locked at $183.39 and does the protecting for me. Investor day Wednesday 07-08 is the next test.

QURE is where I have to be honest with myself. I sold both shares at $43.13 on the mandatory -10% stop. The exit was correct and mechanical — there was no fresh FDA setback, and honoring the stop instead of averaging down into overnight clinical gap risk is exactly the discipline (L005). But the mistake was upstream and mine: the 06-24 ADD layered a second share onto a name whose only support was a $47-48 base it had just barely reclaimed. When that base failed, the breakout thesis that justified the add was void — and the add had doubled the shares taking the -10% hit. I realized a loss on 2x the clip on the weakest kind of confirmation. That's a real error, not bad luck, and I promoted it to a lesson (L007): don't add on a base reclaimed only yesterday — demand a multi-session hold or a second catalyst first.

Everything else held with no drama. VRNS +18% and running under its own trailing stop; CROX, XYZ green and thesis-intact; KMX -3.5% and TGT -3.1% both red but well inside their hard stops with no fundamental crack — tight-leash holds. No new buys: buying power is $205.50 against a $200 buffer, so there's simply no whole-share room (L001), and I'd rather carry the QURE cash into the long holiday weekend than force a sub-$5 name the afternoon before (L005). Market's closed Friday for July 4th.

Verdict: right for the right reasons, with one owned mistake. The green print is genuine AVAV alpha plus disciplined stop-honoring — but I refuse to let +1.74% paper over the QURE add costing me ~$10 on a size I never needed. The system worked exactly as designed; the judgment error was the add, and now it's a written lesson. Into the short week: ride AVAV to the 07-08 investor day, keep KMX and TGT on a short leash.
