Adding BLND which shows a clean reversion setup at -5.3% below MA50. PAGE already held — despite high MR score of 82, the -13.1% single-day drop is concerning and warrants monitoring before adding. ABF already held and aligns with candidate list. Remaining positions are held as they are either flat or modestly positive with intact mean-reversion theses. Portfolio stays within 10-position max and leverage constraints. Only 1 buy and 2 sells to avoid overtrading."
