Inside the BLDR Numbers

	BLDR Price (Builders FirstSource stock price per share)	$75.37
× PE Ratio Versus Sector The PE ratio measures the reported earnings of a company to its current stock price. While earnings are easy to manipulate on the balance sheet, this ratio gives you a sense of what buyers are willing to pay for the stock—what they believe it will do in the future. Comparing a stock's PE to the average PE of companies in its industry gives you a sense of market sentiment about the stock and how well it fares financially. It's not the only number, nor the most important, but comparing similar companies is valuable. A ratio far above or below that of its peers is significant. Industries are more specific than sectors, so companies within most industries are more similar than are companies within an industry. Be aware that the size and customers of companies are important to their prospects. Close ^[?]	PE Ratio versus Sector	14% higher than other Consumer Cyclical stocks

× Cash Yield The cash yield of a stock is the ratio of free cash per share—real dollars available after bringing in revenue and paying bills—to the current price of the stock. It's similar to the PE ratio, but it's less prone to manipulation through accounting practices. In general, the less you have to pay to make more money, the better. Close ^[?]	Cash Yield	2.59%
× Free Cash Flow Jitter The free cash flow jitter of a stock measures how much the company's free cash flow varies from its historical trend, on average. While it's always nice to make more money than you expected, a company with predictable free cash flow is stable and good. A company with wild swings in its free cash flow warrants further research. In general, the lower this number, the better. Close ^[?]	Free Cash Flow Jitter	284%
