Polypore International, Inc. (PPO, Financial), a high-tech filtration company, jumped 31.5% in the quarter, making up for losses early in the year. Auto sales remain strong and electric vehicle capacity is being restarted, so there is hope that sales of separators to electric vehicle manufacturers will start to grow rapidly again. The stock is inexpensive in light of the earnings growth we foresee.
