Added WIZZ (score 88, oversold -18.9%) as top mean reversion pick. Portfolio maintains 9 positions (within 10 max), gross leverage ~2.1x (under 3.0x limit). Avoided overtrading by limiting to 2 sells and 1 buy. Held PROX and UKW (gains) as they haven't reached mean reversion targets yet."

Avoided overtrading by limiting to 2 sells and 1 buy. Held PROX and UKW (gains) as they haven't reached mean reversion targets yet."
