$JAKK vs $MAT: JAKKS Pacific Gains Ground as Mattel Slips -35% JAKK has outperformed in recent months, with shares up sharply year-to-date, while MAT has declined roughly 35% over the same period. Both companies face similar tariff and input-cost pressures, but their recent trajectories have diverged sharply on execution and sentiment. JAKKS Pacific returned to year-over-year sales growth and narrowed losses in its most recent quarter, aided by a rebound in Action Play & Collectibles. Mattel is growing net sales in the double digits but has swung to a net loss as margins compress and leadership transitions add uncertainty.
