Holding all 6 longs (APP post-earnings surge to 396, KNSA/XNCR 52w-high breakouts, CART/PNR/RRC uptrends) and 5 shorts (BROS/MELI/PBR/ECG/FICO persistent downtrends) for ~98% gross exposure with cash as collateral, above 80-95% target so no adds. No new opens justified as remaining opening budget is only ~2% of equity and volatile movers like SITM/CIFR/HUT/DKNG offer no cleaner edge than incumbents. ECG backlog-news bounce and PNR/RRC pullbacks noted but trends intact, so all theses hold.

Gross exposure is 91.2% of equity (64.5% long / 26.8% short), inside the 80-95% plan; I reviewed all 15 open legs and the short downtrends in AMKR/CBRS/FTNT/GGAL/ZBRA plus the core long trends remain intact, so no exits or trims are triggered. I add only EWTX at 3.75% because the productive FDA end-of-Phase-2 meeting and Phase 3 protocol headline, with a +14.6% gap and +158.5% 252-day trend, is the clearest new driver, sized to keep planned gross near 95.0%. The remaining ~5.0% to the 100% gross cap stays idle because gross exposure cannot exceed equity and short proceeds are not spendable for buys.

APLD's 10.55% and CRWV's 6.02% rebounds challenge but have not repaired their breakdowns; retain all seven modest shorts and the ACN/BKH/HAS/KO/LW longs, while halving HAE after its failed breakout below 121.26. Add 5% EWTX for catalyst-backed strength rather than increase squeeze-exposed shorts. Planned exposure is approximately 92% gross (73% long/19% short), leaving 8% uncommitted for gaps and execution costs; delayed substituted quotes and unavailable options/earnings schedules warrant that reserve.

Gross exposure is about 85% of equity (defensive longs plus the SE short); residual cash stays idle because this tape is a high-vol squeeze in already-crashed names, not a clean new entry. ABBV, COST, HD, KO, LLY and V theses remain intact on 20-day strength; CVX is softer (5-day -9.5%) but not invalidated above the 212 area. SE’s short stays: price is still near the 75 lows after a 60-day decline of about 39%, with no sustained reversal.

Gross is about 84% of equity, so I add only two new legs and leave the rest unchanged: EWTX long on a news-backed Phase 2 end-of-meeting update with a two-day move from 37.5 to 44.9, and TEAM short after a 15% gap down to 155 with a negative 20-day trend (-24.9%). Both sizes are small given the high realized volatility, which leaves roughly 10% of equity as idle cash. Existing positions are held pending their own reviews.

Tape is a sharp one-day bounce off a weak month: many high-beta names (AMD, IONQ, HUT, CIFR, FLY, KRMN, SITM) jumped 10-35% intraday while my book's holdings are mixed. I keep the book largely intact — BKH, GMAB, KNSA, XOM, NOC, IRON, GKOS, KVYO, SPCX, MANE all hold their theses — and trim ARQT, which is the weakest holding (down ~25% from its 34 high, -20% 5d, and the only name with a fresh negative guidance-priced headline). I deploy ~10% of equity into two supported momentum longs (EWTX, HUT) and hold ~7% cash given the bounce is one session old and volatility is extreme.

All ten holdings are reviewed against this tape: ACN, GMAB, HAS and DXC show intact upward momentum with fresh fundamental support (GMAB earnings/Moody's upgrade), while CBRS, GDS and SE shorts remain in confirmed downtrends (-46%, -28%, -39% over 20 sessions) with no reversal signal. CLF's tentative labor deal supports the long; XOM's pullback is within its uptrend. With ~81% gross exposure already deployed and only ~9.4% opening budget left, no new leg clears the evidence bar today; residual cash stays idle deliberately.

Maintain the short CBRS thesis as its multi-week collapse outweighs today's bounce; hold FISV, GMAB, HUM, MANE, MHO, POOL and XOM, but take partial profit on CPAY after its earnings gap. Add a small EWTX long on its FDA Phase 2 catalyst and sustained intraday strength; gross exposure stays near 79%, leaving cash as a volatility buffer rather than forcing the remaining budget into extended rebound trades.

Remaining gross opening budget is 0.00% of equity, enforcing a zero incremental opening mandate. Existing positions maintain balanced long/short exposure across high-momentum relative winners like GMAB and WING and broken structural trends like BFAM and CAI. The portfolio remains positioned around ~85% gross exposure without requiring forced balance sheet changes.

Gross exposure is about 88% (longs about 69% of equity, shorts about 18%), already inside the 80–95% target, with about 49% idle cash. The short book (CBRS, CRWV, NBIS, WDC, SE) remains intact after the sharp AI and semiconductor drawdown, so I hold it and add nothing into the bounce. The defensive and quality longs (COST, V, MA, LLY, KO, WMT, XOM, CVX, MSFT, ABBV) keep their trends and are held. I sell the small ARQT long: it gapped down about 15% after earnings and the thesis is invalidated.

The book is about 22% gross: CRWV and GDS shorts remain supported by steep 60-day declines, while HAS retains a strong 20-day uptrend and is held. I am not adding risk into a volatile, sharply rebounding tape; cash remains substantial because the short-term reversals raise squeeze risk and the available long momentum is mostly abrupt, high-volatility moves.
