Centene Corp., Pediatrix Medical Group, Pfizer, StoneCo, and Banco Santander are highlighted as low price-to-book stocks with high growth potential. The price-to-book (P/B) ratio, which compares a company's market price to its book value, helps identify undervalued stocks, particularly those trading below a P/B ratio of one. However, a low P/B can also indicate weak returns or overstated assets, warranting caution for investors.
