ADTRAN Holdings Inc

ADTN remains in a Stage 4 decline after a post-parabola collapse, with a bearish medium-term bias reinforced by sustained forced selling and price trading below declining EMAs and near the 200-day MA. Short-term conditions are extended below EMAs without clear exhaustion, making immediate selling suboptimal; instead, trimming on rallies into the 9- and 20-day EMA zone is preferred, with rejection there as confirmation.
