Reduce the position in HAE · Buy EWTX

From the published explanation

Read full published explanation

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.
