Executives of consumer-products giant Procter & Gamble Co (PG.N), the maker of Tide detergent and other household goods, should consider breaking up the company to improve its beleaguered performance, Barron’s financial newspaper said. The “radical action” would give the Cincinnati-based company a chance to contend with more “agile competitors,” according to Barron’s report this weekend. Procter & Gamble has been struggling with weak performance, with its shares down 17 percent this year.
