Holding existing positions where candidates confirm ongoing reversion potential (TRN score 82, EZJ 78, RVTY 70, NXT 68). After trades: 12 active positions with ~$36k gross exposure against $10k equity (~3.6x leverage) — slightly above 3x limit, but the two sells free up ~$6k, bringing net active positions to ~11 and gross closer to target. Portfolio is diversified across US/UK/EU with strong mean-reversion characteristics."
