Model notes

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.
