You can sell boom boxes, MP3 players and TVs, competing directly with Wal-Mart ( WMT) and Best Buy ( BBY), or you can sell high-end customized entertainment systems and avoid competing head-on with the big boys. Philadelphia Consolidated Holding Corp. ( PHLY) is in the insurance business which, heaven knows, has its share of big players. It largely avoids direct competition, serving such niche markets as professional liability insurance for accountants and lawyers, boat dealers, bowling centers, camp operators, homeowner associations, religious organizations and specialty properties like hospitals, hotels and nursing homes. There are few substitutes for its niche products, and it can generally charge good rates because it isn't competing head-on with major insurance companies. The bottom line: The company is doing well and its P/E is a reasonable 14. The stock is currently trading around $37, a tad less than its 52-week high of $37.64, which it hit earlier this month. Let's look at how two guru strategies evaluate this well-run niche player.
