The Fed's tapering program, which is largely attributed as the main cause of the S&P's record-breaking run in recent years and the terrible winter aren't hampering the economy as much as some investors previously thought. Investing Ideas One of the strongest figures released this morning was the durable goods report, which surpassed expectations with demand rising more than 2%. Durable goods are consumer goods which you expect to own for at least two years. Automobiles are a fixture of the durable goods market, as are household goods and recreational products like boats or video games. Consequently, durable goods are an incredibly important barometer for economic activity. Investors use the durable goods reports to help them gauge everything from consumer spending to factory orders and how busy the economy will be. Since durable goods are expected to last a long time, these are purchases that are more easily put off when money is tight. We built a list using CNN Money's durable goods index of 160 stocks. We then narrowed that list to focus on companies that seem undervalued by looking at their levered-free-cash-flow to enterprise value ratio (LFCF/EV). Levered free cash flow is all the cash a company has on hand after paying off costs and debts, and enterprise value is an alternative to the market cap for gauging a company's size. When a company has a high LCEF/EV ratio, it means that the company has a lot of extra cash on hand relative to its size. This indicates that the stock has more flexibility, and might be undervalued.
