Profitable Stocks to Watch: IBP, FBIN, and MKL

Fortune Brands (FBIN) and Markel Group (MKL) are two companies with declining profitability and constrained growth potential, while Installed Building Products (IBP) is a company to watch due to its strong operating margin and potential for future growth. FBIN's core business is underperforming, and expenses have increased as a percentage of revenue over the last five years. MKL's large revenue base constrains its growth potential, and projected sales decline for the next 12 months point to a tough demand environment ahead. IBP, on the other hand, has a strong operating margin and potential for future growth.
